Implementing an ISO 9001 Quality Management System

Implementing a quality management such as ISO 9001:2008 requires transforming the culture. It will affect the entire company, not just the quality department. More people in the organization are affected by it than just the management representative, or the person spearheading the effort. Implementing a quality system to the point of certification and registration is a daunting task but is achievable with your current resources. Implementation times can vary but it can be accomplished.

When considering implementation of a quality system such as ISO 9001:2008 you should consider "why are you doing it?" Companies pursue quality system implementation for various reasons, to become better, their customer's are requesting it, they are having quality problems or they would like the recognition of being certified. In either scenario, the circumstances are different as will be the driving force to implement the quality management system. An organization should consider the benefits of having an ISO 9001:2008 quality system and are not concerned about flying the flag. The following steps best describe the implementation process:

1. Why do you want to implement an ISO quality system?

3. Commitment from Top Management

4. Select a Management Representative

5. Select Implementation Team

8. Gap Analysis

9. Create an Implementation Plan

10. Employee Training

13. Internal Audits

14. Select Registrar

15. Management Reviews

16. Continual Improvement

17. Pre-Assessment Audit

18. Registration Audit

Why implement a quality management system such as ISO 9001:2008 To understand why you would consider implementing a quality management system, let us understand the various quality management systems. There is the ISO 9001:2008 standard along with the industry specific standards such as ISO/TS 16949 (Automotive), TL 9000 (Telecommunications) and AS9100 (Aerospace). In addition to these standards is the Malcolm Baldrige Award.

The ISO 9000 standards cover all areas of control which has a potential to impact the degree of compliance of a product or service. The standard is not a cookie cutter quality system that means you will have the same quality system as your competitor, or customer. It means you will have quality systems that meet the minimum requirements but the details of how the requirements are met can vary dramatically.

There are several misconceptions surrounding the standard, one is it creates a great deal of non value added paperwork, another misconception is it does not provide any value because all I have to do is "say what I do and do what I say" and they third misconception is it restricts creativity by burdening employees with structured approaches.

Addressing the first concern of generating non value added paperwork. The belief is you must document, document, document everything you do. Actually, the standard requires one quality manual, six procedures, instructions where necessary and 26 records. This may sound like a lot but it really is not. The need for extensive documentation can be mitigated with a thorough training program that reinforces what is to be done and how it should occur. It is common for companies to utilize more documentation than the standard requires, simply because they find it valuable. When you are in an environment of continuous change and improvement, processes, duties and tasks are continually changing to keep pace with improvement. It could be extremely hard to know what the agreed upon method was without a formal documentation and change process. The end process would drift because the tasks within the process drift. It would be analogous to not having maximum speeds posted; they would be verbally communicated from area to area.

The second misconception is that the standard does not really benefit a company because it simply means you documented what you do (even if it is wrong) and you can show you do it. I recall an example when I was touring a manufacturer and I could see they were lacking in quality systems. I asked the Vice President of Quality if they considered adopting an ISO quality system. He replied, "ISO is nothing more than doing what you say you'll do. We could make cement life jackets and we could get certified. Our customers wouldn't buy cement life jackets". I listened to what he said (laughing inside) and suggested he get some training on the standard, because that is not the intent. The current standard focuses on ensuring you provide a product or service that continually meets the requirements of the customer with the aim of improving customer satisfaction. To make a long story short you could have a system that is extremely well documented and everyone follows the procedures and instructions. If this system is not producing an output that is meeting the requirements of your customer you will not get certified, end of story. Understand, the documentation portion of the standard is a tool or method, the end game is customer satisfaction and meeting you business goals.

The third misconception perceives the standard as restrictive in that it binds employees into a specific, structured way to do their job. It removes creativity and replaces it with a mundane repetitive approach. This is to some degree true and dependent upon the organization. The level of control is at the discretion of the company. My experience supports having a level of structure that is consistent with achieving the desired output of the process. For example, if the process is purchasing, the desired output is to have quality product delivered on time in the correct quantities.

The ISO 9001:2008 quality system standard provides an organization with a solid quality management system to build upon and improve. The objective of the ISO 9001:2008 standard is to provide a guideline which enables an organization to deliver a consistent product or service that meets the customer's requirements and strive to enhance customer satisfaction. The requirements within the standard are developed for a company to maintain a predictable output from their key business processes and continually improve those processes.

ISO 9000 is a combination of three quality system standards, ISO 9000, ISO 9001 and ISO 9004. The ISO 9000 standard covers the concepts and vocabulary. The ISO 9004 standard is guideline for improvement. The ISO 9001 standard is for quality system requirements and is the only standard with requirements. ISO 9001:2008 means the ISO 9001 standard with the revision year of 2008. From this point forward when I reference the standard I am referring to the ISO 9001:2008 requirements standard.

Is an ISO 9001 quality system right for you? To answer that you must first answer why are you going to implement and possibly get certified to the standard? Let me give you a few scenarios that may help.

Scenario 1 Your company is doing well. Your sales are increasing, you have little or no competitive pressure to reduce costs and upper management is happy with the current state of the company and the business climate. Your customers are not requesting you to become certified and do not perceive a competitive advantage with having an ISO 9001:2008 certification. Implementing and becoming certified to the standard is probably not right for you at this time. Chances are you will not get the support you need or convince anyone in upper management there is a need. Could implementing an ISO 9001 quality system improve your current situation? Absolutely, you could see cost savings and improvements in all types of areas. Implementation is more of timing thing and right now sounds like the wrong timing.

Scenario 2 Your company is doing well. Your sales are increasing, you have competitive pressure but your current business practices are able to keep you competitive. Upper management is happy with the current state of the company, but your customers are requesting it of you. You are pursuing ISO 9001:2008 certification because your customers require it. I have experienced this difficult situation many times. The major obstacle is that nobody in the organization wants it or realizes a need for it. The driving force is external. An ISO 9001 quality system will probably be implemented and certified. The big question lies in the long term effectiveness and sustainability of the system or is it only needed to "fly the flag". You can approach this by learning as much as you can about the standard so you can speak intelligently about it. You will continually "sell" this program to upper management to obtain their buy in. Once the benefits of the program begin to surface, your selling efforts will diminish.

Scenario 3 Your company is doing marginal to bad. Sales are level to decreasing; you have quality problems that are adding a lot of cost. You are experiencing pressures from global competitors. Upper management is not content with the current state of the business, but they are unsure what to do. The climate is good for implementing an ISO 9001 quality system. If you can convince top management of the benefits and expected results of having a quality system this can be very good environment for implementation. You can choose to not become certified, you will gain benefits by simply having a quality system modeled after ISO 9001:2008. The benefits of having a structured quality system will provide the incentive and reward. Having implemented ISO 9001 quality systems in all three scenarios, experience has proven scenario 3 is the best. It is much easier to achieve buy in and commitment from the top.

The overwhelming question for top management to answer is "why are we doing this and what do we want from it?" Understand why you are doing it and be fair regarding what you want from it. Don't go in with expectations of an elite quality system generating a great deal of benefits if you're going to seek the path of less resistance toward implementation and registration.

Educate Top Management The education process for top management is a two-part approach. One part is to educate them on what ISO 9001:2000 is, the benefits, how it fits into your current business and what it will take to implement the system and be certified. The second part is to educate them and ensure they understand why they are doing it and what the challenges are.

What are the ISO 9000 standards? We discussed this previously; ISO 9000 is a combination of three quality system standards, ISO 9000, ISO 9001 and ISO 9004. The ISO 9000 standard covers the concepts and vocabulary. The ISO 9004 standard is guideline for improvement. The ISO 9001 standard is for quality system requirements and is the only auditable standard.

The ISO 9000 standards are internationally recognized. They are developed, maintained and revised by the International Organization for Standardization or ISO. ISO maintains thousands of standards. The ISO 9000 standards deal with quality management. You may have heard of ISO 14000 which deals with environmental management.

The ISO 9001:2000 standard is adopted as a national quality system in more than 100 countries throughout the world. There are over 700,000 ISO 9001:2000 certificates issues in more than 140 countries worldwide. The number of certificates in Europe exceeds 200,000; the number in the US is over 60,000 with an estimated 30,000 organizations currently pursuing ISO 9001:2000 certification.

The benefits of an ISO 9001:2008 quality system The soft benefits of an ISO 9001:2008 quality system are improved quality and customer satisfaction. The hard savings come in the form of a tangible reduction in the cost of quality. Appraisal costs will decrease significantly as will failure costs. A slight increase in prevention costs should be observed, which is desired, but the savings in the other two areas will overshadow the slight increase you see in prevention costs. For a quick review, appraisal costs are those costs associated with inspecting, evaluating and testing. Failure costs are costs associated with scrap, both internal and external along with warranty. Prevention costs are associated with quality planning, fmea's, control plan development and quality engineering. Depending upon your company's current situation including market, size, business practices and culture, it should be safe to estimate a savings in the area of 1% of sales. There is no reason why you can't realize savings of up 2 - 5% of sales. This amounts to approximately ,250,000 annually for a ,000,000 company. On average for a ,000,000 company you could expect savings in the 0,000 range. Where do the savings come from? They are in the form of reduced inspection, rework, scrap, warranty and handling customer complaints. How does the implementation of an ISO 9001:2008 quality system realize cost savings? It is estimated that approximately 75% of the total quality costs are the result of internal and external failures. For a manufacturing company, failure costs are associated with sorting or reworking product. For a service company, examples of failure costs would be working with a customer to resolve a problem or revising documents because they were not done correctly. Having a quality system in place will reduce significantly the amount of failure costs incurred. You will also be able to reduce the amount of appraisal costs or how much you test, inspect or validate the product or process. Below is an example of the savings realized by a company after implementing an ISO 9001:2008 quality system.

A study was completed that showed a company reduced it's total cost of quality from ,323,302 to 8,567.  These are staggering improvements. Keep in mind that sales remained level but direct labor hours did not. A reduction in direct labor hours was observed due to process improvements. The cost of quality breakdown does not include financial gains in productivity, inventory reduction and reduction in changeover time. An important feature to recognize in the chart above is the shift in costs from appraisal and failure category to prevention.

The important thing to remember is the savings are only visible if the accounting systems are in place to accurately report them. The process to capture, report and analyze the cost of quality is very detailed and beyond the scope of this article. There is a financial reward for implementing an ISO 9001:2008 quality system.

How ISO 9001:2008 fits into your current business model The thought of a quality management system similar to ISO 9001:2008 brings fear to people because they believe they have to adopt someone else's program, or force a system or method to work for them. The intent of the standard is to adopt a system that works for you. You could benchmark a company and observe how they determine customer satisfaction and your first thought is, "that would never work at our place". That is alright, there is more than one way to "skin a cat".

Here is the best piece of advice I can offer, there is no best way to implement a process or create a system. There is no single best method or the right way to do it. That is where continual improvement becomes important. Don't become overwhelmed with trying to find the one correct method, get something implemented and continually improve it. The power and value with the standard is that you start somewhere and improve. Not everyone starts at the same place or ends at the same place. This endeavor to implement an ISO 9001:2008 quality system does not end with certification. Not all ISO 9001:2000 registered companies quality systems are the same. Just like not all doctors, lawyers, teachers or car mechanics are the same. They all have certifications and credentials but differentiation lies in their approaches to the job.

The implementation and maintenance of a quality management system can be tailored to a specific company. Don't confuse this with allowance to not meet the requirements. It means there are many ways to meet the requirements. You can choose to meet the requirements or you can choose to exceed the requirements. It is dependent upon the organization. My hope is that should you adopt the ISO 9001:2008 standard and implement it, your decision is to do more than just simply meet the requirements of the standard. This is where so many companies fall short in realizing gains from a quality management system. They do just enough to meet the requirements but never push themselves to exceed. The implementation of a quality management system is like anything else in life, you get out of it what you put in.

What it will take to implement ISO 9001:2000 This is dependent upon how fast you want to go, status of your current business practices and what type of resources you have. A typical timeline would be a year. I see no reason why you can't go from where you are now to certification in one year. Can you do it quicker, say six months, three months, yes. It just takes time and money. Time and money can cure just about anything. I wish it could cure everything, but unfortunately it can't.   From a human resources standpoint, for a single location company of about 500 people it will take about 4500 man-hours to implement on your own. Keep in mind a portion of that time will be consumed because it's new to you. It wouldn't take a consultant or someone with experience that long because they've done it before. If you hire a consultant you can reduce the amount of time it takes, but you will spend it in consulting fees. A good estimate would be about 8 man-hours per employee to complete it in a year by yourself. At an estimated cost of per man-hour, you may look at it as ,000 for a 100 person operation (8 x 100 x 25) = 20,000. One thing to keep in mind is the people working on the project are there anyway, you are not hiring extra people. You are going to temporarily reassign resources to accomplish the goal.

Now let's look at the cost to get certified. Depending on the registrar you select and we'll talk about that later, the costs can vary slightly. A good baseline for costs to become certified and maintain certification, are as follows:

Document Review 0 onetime cost, pre Assessment Audit ,500 Registration Audit ,500 one time cost Surveillance Audits ,500 ongoing annual cost

Training costs should be in the ,400 - ,000 range for internal auditor training. You can cut some costs of training by having one person in your facility trained and then have them train your internal auditors (,400) or you can have all of your internal auditors trained by an outside source (,000).

Commitment from top management I can't teach you how to get commitment from top management, I'm not that good, and nobody is. What I can teach you is how important it is, what it means and how to tell if top management is really supporting the implementation of a quality system. Can you implement an ISO 9001:2008 quality system without top management support and commitment? Yes, but the resultant quality system will not be as effective as it could be and you will probably find yourself asking where the benefits are. You will question the validity of the standard and the quality system because you won't see a dramatic change in your complaints, quality levels, quality costs and warranty. You can implement a system, pass a registration audit and get your company ISO 9001:2008 certified. I have seen a large number of companies that are certified but are not reaping the benefits of the standard or the quality system. The root cause of this is most often top management support.

In an attempt to avoid this scenario, it is important to educate top management of the commitment requirement and the ramifications of falling short. Educating top management does not guarantee the commitment. When the results are not there and people begin to question the initiative, you can point to this as a possible way to right the ship.

Top management commitment does not mean they verbalize it. When it comes to an endeavor such as implementing an ISO 9001:2008 quality management system, people will not care what you say; they want to see what you do. It will be extremely difficult to get momentum when top management talks the talk but will not walk the walk. Employees at all levels of the organization will be watching to see if this is real, or is it another "flavor of the month". They won't look at the management representative singularly; they will be watching the members of top management and particularly the highest ranking individual at that site.

That individual must provide continual support for the implementation process. They achieve that with actions that are consistent with what is spoken. For example, a situation exists where an area is having problems with a specific supplier. This has been occurring for six months and no activity is taking place. People will not believe top management is serious or supports the implementation of a quality system if this occurs. Take the same scenario but now the top ranking individual communicates to the employees what is being done and when. This is a big step. The biggest step is doing something to correct the problem.

The key for top management is to be visible and active in the effort and have their actions consistent. If this hasn't been a characteristic of top management at your facility then they need to change. Can it be implemented without this, yes but as we stated above it will be much more difficult and the results you get will be significantly reduced. This effort can't be viewed as something the quality manager, improvement manager or any other anointed person does. This must be an effort spearheaded, guided and monitored by top management. If it is not, everyone associated will know and the progress will be slow, the results will be substandard and your frustration level will be high.

Select Management Representative and Implementation Team The management representative is the person who has the responsibility to report on the status of the quality system and is most often the person who will spearhead the efforts. This person oversees the implementation process and is responsible to ensure management is aware of the condition of the quality system in order to facilitate continual improvement. It is not imperative this person is part of top management, but it does help. If the management representative is not a member of top management make certain they have direct report to someone in top management. The management representative is to the ISO 9001:2008 implementation what a black belt is to a six sigma project. They are the catalyst that makes the reaction move. Important characteristics of a management representative are forward thinking, change agent, and embody continual improvement, positive thinking and not content with just getting by.

The next step is to identify the implementation team. This can vary depending upon the size of the organization. A 500 person facility could have an implementation team of perhaps 10 - 15 people. A 50 person facility could manage with an implementation team of 1 to 2 people. For the implementation team you're looking for some resources that could carve 1 - 2 hours per day out of their schedule and work on the ISO implementation. You are also looking for change agents within the company. You do not want to fill your implementation team with individuals who are antagonistic, negative thinking and happy with simply doing what it takes to meet the requirements.

Top 10 Greatest Love Songs of All Time

9. You're Still the One - Shania Twain

Perfect for the First Dance at a wedding with the lyrics saying "looks like we made it". The song talks about how her love still survives and goes on even though the odds were against them. Chorus: "You're still the one I run to, the one that I belong to, You're still the one I want for life."

8. You're the Inspiration - Chicago

Written by Peter Cetera in 1984, it is a little bit more on the cheesy side, but nonetheless a great song classic love song. Chorus: "You're the meaning in my life, you're the inspiration."

3. I Could Not Ask For More - Edwin McCain

A somewhat newer song released in January of 2000, this is a great slower love song with nothing but a positive message to offer. Chorus: "I could not ask for more than this time together. I could not ask for more than this time with you."

Top Ten House Alarm and Home Security Devices

A man's home is his castle, as the saying goes. But homes today don't normally feature ramparts, drawbridges, moats and six-foot thick stone walls to keep out unwanted visitors. Today, a house alarm, and preferably a managed home security system, is needed to ensure your home's security. Not only does installing a home security system improve the safety of your family and possessions, but it can also decrease your home insurance costs. The Top Ten House Alarm and Home Security Devices list highlights ten devices and features of home security systems that can make your house a safer place.

The Top Ten

Portable Speaker Review

10. Talking Devices help you to understand the status of your home and monitoring as well as program the system. Some security systems feature talking master control panels, key pads or remotes. The talking feature may not result in great conversation, but it will help you understand your system a little better.

Top Ten House Alarm and Home Security Devices

9. Some home alarm systems include extras like Key Fobs and Remotes to control the system at a distance. Somewhat similar to a car's key fob, home security key fobs include buttons to activate and deactivate the house alarm system. Some even include a "panic" button that activates the house alarm and alerts the proper authorities in the event of an emergency. Remote controls are similar and often larger. The features of remotes vary greatly and can include a full key pad, a talking feature and a panic button as well.

8. Yard Signs and House or Window Decals advertise your home's protection. The Greenwich Study of Residential Security found that homes without alarms were 2.7 to 3.5 times more likely to be burglarized, and that the most effective deterrent was the alarm monitoring company's yard sign (SIA Research Update, Security Industry Association, October 2001). Some choose to post the signs to deter possible break-ins without actually installing a home alarm system. While this effort will lower the odds of an attempted burglary, a yard sign alone cannot fully protect your home.

7. A Back-Up Power Supply is important in maintaining home security even during a power outage, when the risk of break-ins and looting is increased. Your home alarm should be effective even when your power is not. The easiest to maintain back-up power supplies use standard size batteries. Look for a model that uses rechargeable batteries to lower your maintenance costs.

6. Smoke Detectors add another layer of protection to your home, especially when they are integrated into the home alarm system. Not only do smoke detectors indicate a fire and give you time to escape safely, but when included in a home security package, they automatically notify the managing company and the fire department. Some systems even integrate the power supply to the smoke detectors. That means you don't have to change the batteries ever!

5. Wireless Systems protect your home without adding extra cords to trip over or extensive installation of in-wall cords. In wireless house alarm systems, each sensor or keypad communicates with the master control panel via radio frequencies or existing wiring in your home. A burglar will never be able to disarm the system by snipping the wires. This ensures the system is fully integrated and monitoring all parts of your home without using up your outlets or creating an obstacle course of wires for you.

4. Extra Key Pads are also important. Exterior mounted key pads can provide secure keyless entry to your family. Some systems also offer remote control key pads which are lightweight and portable. A home alarm system that features a security code with a key pad increases the security of your home. A monitored system can also lock down entry after several repeated, failed attempts at entry which indicate a possible break-in attempt.

3. Key pads may not always be enough to keep burglars out. Sensors on Windows and Doors reduce the risk of a burglar entering undetected and are a key part of a home alarm system. Motion Detectors within the home also increase the level of security. The most sophisticated motion detectors include a feature to ignore pets' movement to avoid constantly setting the alarm off inadvertently.

2. Installation, Monitoring, and Repair Services increase not only the level of safety but the convenience of keeping your home safe. A house alarm alone cannot notify the police or fire department in the event of an emergency. The most complete systems include buttons to notify police departments, fire departments and medical help instantly. Another advantage offered by the best monitoring companies is live customer support and full service installation and repair of the system by employees who have been background checked, licensed and drug tested to ensure your safety. Finally, some companies even offer relocation services to keep you secure even when you move.

1. The classic Master Control Panel is vital to any home alarm system. The central hub of the system, the control panel is usually wall-mounted in an easily accessible place. The panel receives information from all other sensors and key pads, computes it, and transmits relevant information to the monitoring company. If you choose to arm the system from the panel when you leave the house, the master control panel also receives the disarm code when you return home. Some can even be disarmed by telephone!

Of course, this list is not comprehensive, and the needs of every home and homeowner are different. For more tips on choosing the right home alarm system and features to protect your house, I recommend visiting alarmoneinc.com.

Thumping Sound in Ears - Pulsatile Tinnitus

What's The Difference Between Tinnitus and Pulsatile Tinnitus?

Pulsatile tinnitus may just be regarded as an ordinary form of tinnitus, save for the humming or ringing sound. This type of tinnitus is distinguished by a thumping sound in ears similar to that of a beating heart. It may be more bearable and less irritating compared to the usual ringing sound of having tinnitus, but mind you, pulsatile tinnitus is a bit more dangerous because it involves the flow of blood to and fro the head.

As previously mentioned, the thumping sound one may hear is in rhythm with the person's heartbeat. Don't be surprised because pulsatile tinnitus is associated with blood flow related disorders. Also, unlike the common tinnitus, the sound in the ears may possibly be noticed by another individual.

Thumping Sound in Ears - Pulsatile Tinnitus

In addition, do not regard the pulsating sound in your ears as something natural for it's not. Bear this in mind, such condition calls for medical attention. Out of 30 people with tinnitus, one of them is suffering from pulsatile tinnitus. And akin to the typical tinnitus, the pulsatile type has no direct cure yet. Medical professionals treat the underlying causes instead, along with prescribed drugs to alleviate the symptoms.

What Causes Tinnitus?

What are the causes of pulsatile tinnitus? Blood vessels constriction is never a good occurrence particularly in the head or neck area. Such narrowing is the primary cause of the thumping or beating sound in the ears. This is brought forth by the flow of blood through the compressed blood vessel. It is noticeable because the vessels are adjacent to the ears. Moreover, pulsatile tinnitus also takes place due to other serious medical conditions such as atherosclerosis, tumors, injuries, and high blood pressure.

What Are Some Treatments to Tinnitus?

Naturally, a series of tests have to be conducted for a medical practitioner to distinguish the cause of the problem. Often, an X-ray provides a visible answer. If an X-ray shows nothing, a magnetic resonance imaging or MRI is conducted. It is important for a patient to tell the doctor how and when the symptoms first took place. This is vital so that the attending physician can thoroughly order the crucial tests to be done, so as not to leave any stone unturned.

Like the ordinary kind, symptoms of the pulsatile tinnitus can be pacified by prescribed drugs. However, the fundamental cause has to be separately treated, like hypertension. In this case, medications are vital to normalize or regulate blood pressure. Lifestyle and diet must also be modified, coupled with regular work-outs to keep blood pressure at a normal level.

Again don't forget that pulsatile tinnitus requires medical attention. Due to the involvement of the circulatory system, always be mindful of the critical complications that can arise from a seemingly innocuous symptom. Don't wait for anything dreadful to happen. Seek medical help before it is too late. Early detection and immediate intervention will definitely save your life. Don't allow your tinnitus to cause more serious complications and put your life at risk. Act now!

Write Your Family History - 50 Questions You Must Ask Parents Or Grandparents Before They Die

No one expected it.

While climbing into his hot tub, my healthy 87- year-old father-in-law slipped, fell, and broke a rib. He began internal bleeding that the doctors couldn't stop. In two weeks, Gene was gone.

Fortunately, we had taken time a few months earlier to record Gene's life story, and discovered some amazing facts. He was a semi-pro baseball player, a fine watercolorist, and a US Marine. As a marketing executive for Kaiser and later Del Monte, he worked on national advertising campaigns with mega-stars of his day, including Joan Crawford, Debbie Reynolds, Stan Musial, Lloyd Bridges and others.

Write Your Family History - 50 Questions You Must Ask Parents Or Grandparents Before They Die

We recorded Gene's life story on two occasions: once at a small family dinner, then during a living-room interview a few months later.

We transcribed the audio files of the recordings, added pictures, and then uploaded the whole package to a new free web site that helps people write great personal and family stories. (See resource section,below). Gene's family and friends can view his story and add comments or photos if they wish. The profile that we co-created with Gene is a celebration of his life. It's also a direct, meaningful connection with his daughters and their grandchildren. Anyone can create a life story for themselves or a loved one. It's as simple as setting aside some time and doing some careful listening.

I've helped hundreds of people across the US, Canada, and Mexico capture their life stories. Based on hundreds of hours of interviews, I've boiled down my experience into three key tips, and the 50 most productive questions you can use for success.

Success Tip #1: Pre-Interview Preparation is Key

To get the most from your family history session, be as prepared as possible.

. Inform the subject of the purpose of the interview, who will see it, and how it will be used · Prepare your questions in advance · Set aside a quiet time and place free from interruptions

· It's a good idea to use a voice or video recorder; test all equipment thoroughly before starting

· It's often useful to use a tape or digital recorder and transcribe the dictation

· Photos, mementos, or other visual aids are great memory-joggers. Ask your subject to prepare some in advance

· Listen attentively and gently; ask questions of clarification

· Don't try to force the subject into something they are uncomfortable discussing

Success Tip #2: Be Flexible and Creative

When I first started doing life story interviews, it seemed as if people spent the majority of time talking about their early days. As I got more experience, I began to realize that most people have one, two or possibly three key defining times in their lives. For many, it's childhood. For a lot of men, it's WWII, Korea, or Vietnam. The defining moments emerge like finding a gold nugget in a streambed. Be sensitive to these defining moments and episodes. Listen extra-carefully, and ask questions. Often a deeper portrait of an individual emerges, laden with rich experiences, values, beliefs, and layers of complexity. If you don't complete the interview in one sitting, set a date to resume your conversation later

Success Tip #3: Organize Life Stories into Chapters

Most people (yes, even shy ones) love to be the center of attention and share stories from their lives. There are two challenges for a family historian. The first is to capture the stories in a structured, logical way. The second is to make sure that the stories are as complete as possible and contain facts (names, dates, places), fully-drawn characters, a story line, and perhaps even a finale. The GreatLifeStories web site divides the life experience into 12 "chapters" that follow the progression of many lives. On the web site, each chapter contains anywhere from 10 to 25 questions. (Below, I've selected the 50 questions that usually get the best results). Don't worry; you don't have to ask them all. In fact, after one or two questions, you may not have to ask anymore-the interview takes on a life of its own.

The most important objective is to make sure you cover as many of the chapter headings as possible. The chapter headings are logical and somewhat chronological in order: Beginnings, School Days, Off to Work, Romance and Marriage, and so forth. Feel free to add your own chapters, as well. The 12-chapter system is a great way to organize both the interview, as well as the life story write up, video, or audio recording.

CHAPTER 1: In the Beginning

1. What were your parents and grandparents full names, dates of birth, places of birth.

3. What lifelong lessons did you learn from these tough times? Joyous times?

4. Were there any moments you recall as true breakthroughs in any area of your life?

5. If you could do one thing differently in your life, what would that be?

CHAPTER 10 Words of Wisdom

1. What have you learned over your lifetime that you'd like to share with the younger generation?

2. People will sometimes repeat aphorisms such as "honesty is the best policy." If they do, be sure to ask how they learned that life lesson.

CHAPTER 11: Funnybones

2. How have you taught your children to be grateful?

3. Are there items or places that mark special gratitude for the ones you love? What are they? What are their stories?

In closing, it is always a good idea to ask an open-ended question such as:" Is there anything I haven't asked about that you would care to comment on?" You'll often be surprised and delighted at the answers!

Small Telephone Systems Verses Multi-line Business Phones

Choosing the right telephone system from start is always the best path, but not always the most economical. Before you head down to your local electronic store and pick up the cheapest multi-line business phone you can find, here are few pointers you should keep in mind.

Many multi-line business phones have a pretty decent feature set such as voicemail, caller ID, call waiting ID, 3 way calling and intercom (in multi phone setups). These phones integrate the Key System Unit (or KSU) into the phone itself, which means each individual telephone functions as its own "mini phone system." The term KSU, (Key System Unit, Key Signaling Unit or Key Service Unit) dates back to the early day's phone systems, it's basically "the Brain" of the phone system. All call processing data and telephone line interfacing is carried out by the KSU. For many small offices with less than 4 phones (extensions) and 4 telephone lines, these multi-line phones are adequate and economical. However, as a business grows, the many disadvantages of these phones begin to show their merits.

By comparison, multi-line business phones are sold with the marketing term, "KSU-less design," which translates (in buyers minds) to lower overall costs. Small telephone systems on the other hand include a separate KSU unit or "Brain" in addition to each telephone. A major disadvantage comes to play when you are interfacing your phones with the telephone company lines. The KSU acts as the "line interface," for a phone system, all major system connections terminate at the KSU. Now with each multi-line phone acting as its own "mini phone system," each phone now needs direct connections to each telephone line.

Small Telephone Systems Verses Multi-line Business Phones

A single telephone line consists of 1 pair of wires. Almost all multi-line phones support up to 4 lines, meaning each multi-line phone needs up to 4 pairs of wires or the equivalent of a standard Cat5e cable. As you begin to add more KSU-less phones to your office you must factor in the cost to install another drop of cat5e (or cat5) cable. You must also account for the additional termination blocks in your telephone closet where all these phones must be "Bridged" (or shared) to the 4 phone lines. As you can imagine, for installations with more than say 4 or 5 phones the wiring aspect can get pretty complex. Anything over 6 or 7 phones will be a wiring mess, if done unprofessionally, which adds to the cost of these low budget systems. However, this bridged connection is how multi-line phones "intercom" one another. By sending a signal over each bridged line, each extension can communicate without actually tying up any of the 4 phone lines. As long as every multi-line phone is connected to all 4 lines (or matching number of lines if less than 4), each phone can intercom each other internally while keeping the phone lines free for external calls.

Small Telephones Systems on the other hand, which come equipped with a separate, dedicated KSU unit, are at a distinct advantage in both areas. Having a single KSU unit means a single interface point for the telephone line connections. Many small telephone systems need only a single pair of wire to connect each extension telephone. What this means is if you are deploying a number of phones in one particular area, you can save dramatically on cabling costs by having your contractor "split" the single Cat5e cable into, at most, 4 single telephone jacks! - This becomes very cost effective as you deploy additional phones. (However, many pros will only split single Cat5 cable once for 2 telephone jacks leaving the remaining wires as spare pairs). Cable management becomes much easier (and neater) as you need not worry about bridging 10 phones to 4 telephone lines. One single pair of wires (to connect to a telephone) of the 3 or 4 pairs in a standard telephone cable is enough for as many lines as the small telephone system can handle since the actual line connections are at the dedicated KSU unit and not at the individual telephone.

Another plus for the small telephone system is the ease of transitioning to a larger phone system. The wiring scheme for the most part will remain the same albeit installing more cable drops to new areas. Not so much the same for the multi-line business phones. Depending on how each phone was "bridged" to interface to those 4 telephone lines, this entire wiring scheme may need to be undone as most small (and large) telephone systems require individual (not bridged or shared) connections to the KSU.

Programming wise there is one disadvantage when comparing small business telephone systems to multi-line business phones, which can be viewed as multiple disadvantages. Since each individual telephone functions as its own KSU it also functions as its own Voicemail unit (if equipped). Which means if you want to enable an Auto Attendant feature (where your callers are greeted by a company recording instructing them to press 1 for Joe Boss, 2 for Sales Manager etc...) you will have to record this greeting for as many times as you have voicemail enabled phones (up to 4). Here's why, with most multi-line business phones, the voicemail feature includes a personal voicemail box for the extension and an optional auto attendant feature. The auto attendant feature can only handle one call at a time; ergo if you want the system to answer up to 4 incoming calls simultaneously you need at least 4 auto attendant enabled phones. So technically speaking you must record the same auto attendant greeting 4 times, 1 on each phone. You must also enable the system mailbox for each of the 4 phones to accept general messages. You now have 4 different phones/voicemail boxes in your office where you must check for general messages. This is known as a general mailbox, which is a default destination for callers who do not press a menu option or dial an extension. This scenario is not efficient for larger setups but may work for smaller ones.

With a small business telephone system, there is just one central voicemail unit which can handle multiple calls at once. Storage times are much greater and there is just one mailbox for general messages. You can also take advantage of advanced features (if equipped) such as voicemail to email (where the system sends the voicemail in a standard wav format to your email address), which in this fast paced world can be a BIG time saver and added convenience.

One last point on this topic to cover quickly; with the advent of the Voice over Internet Protocol (VoIP) continually proving its cost effective existence, many businesses find themselves wanting to take advantage of these savings. Many small business telephone systems on the market today are equipped to handle VoIP telephone lines through either a simple hardware or software upgrade. An upgrade may include adding an Ethernet (or media) port to the system or if already equipped, simply enabling this port through software activation. Simply plugging this unit into your company LAN and perhaps minor firewall configuration you can now start saving on land line costs by calling out over less expensive VoIP lines.

Multi-line business telephone can benefit as well but through a 3rd party VoIP gateway. This gateway converts a VoIP line (sometimes called a "Trunk") to a standard telephone port. You will need as many gateways as you want lines, (or opt for a multi-port unit). However you may have to plan on spending some time configuring and adjusting the settings of the unit to obtain the proper volume levels while minimizing echo and other artifacts that may be induced when converting the signal from a standard Analog telephone line to SIP or other VoIP protocol. Many high end units come with built in (hardware or software) echo cancellers and noise suppressors which minimize these adjustments (and work very well) but increase the cost of the gateway dramatically.

To conclude, although it may seem like great savings early in your start up phase, for needs of 4 or less external lines and extension phones, the multi-line business phone can actually prove to be a cost effective solution. In my humble opinion these multi-line phones are better suited for a home office (or SOHO) situation. If you have big plans to expand exponentially (and don't we all!) I recommend you at least consider a small business telephone system. Although a bit more initial investment is required, the benefits far out way the cost disadvantage if not cancel it out completely.

If you're looking for a great small telephone system to start out with that's not too advanced and bloated with "bells and whistles," I recommend the XBlue Networks X16 small office telephone system. This system is priced right smack in the middle of a decent multi-line business phone setup and an advanced small business telephone system. XBlue Networks hit the nail on the head with this model by stripping off only the advanced telephone features most small business may not have a need for, or are rarely used; allowing the X16 small office phone system to fill a niche in the market left primarily untouched. This compact, stylish phone system offers some nice designer phones to choose from (for those wishing to be unique) and a great feature set.

If you're local to the New York City metro area, PBX Interactive, LLC currently has a great promotion going on for these small telephone systems.

The History of Video Conferencing - Moving Ahead at the Speed of Video

No new technology develops smoothly, and video conferencing had more than its share of bumps along the way before becoming the widely used communications staple it is today. The history of video conferencing in its earliest form goes back to the 1960's, when AT&T introduced the Picturephone at the World's Fair in New York. While viewed as a fascinating curiosity, it never became popular and was too expensive to be practical for most consumers when it was offered for 0 a month in 1970. Commercial use of real video conferencing was first realized with Ericsson's demonstration of the first trans-Atlantic LME video telephone call. Soon other companies began refining video conferencing technologies, including such advancements as network video protocol (NVP) in 1976 and packet video protocol (PVP) in 1981. None of these were put into commercial use, however, and stayed in the laboratory or private company use. In 1976, Nippon Telegraph and Telephone established video conferencing (VC) between Tokyo and Osaka for company use. IBM Japan followed suit in 1982 by establishing VC running at 48000bps to link up with already established internal IBM video conferencing links in the United States so that they could have weekly meetings. The 1980's introduce commercial video conferencing In 1982, Compression Labs introduces their VC system to the world for 0,000 with lines for ,000 an hour. The system was huge and used enormous resources capable of tripping 15 amp circuit breakers. It was, however, the only working VC system available until PictureTel's VC hit the market in 1986 with their substantially cheaper ,000 system with 0 per hour lines. In the time in between these two commercially offered systems, there were other video conferencing systems developed that were never offered commercially. The history of video conferencing isn't complete without mentioning these systems that were either prototypes or systems developed specifically for in-house use by a variety of corporations or organizations, including the military. Around 1984, Datapoint was using the Datapoint MINX system on their Texas campus, and had provided the system to the military. In the late 1980's, Mitsubishi began selling a still-picture phone that was basically a flop in the market place. They dropped the line two years after introducing it. In 1991, the first PC based video conferencing system was introduced by IBM - PicTel. It was a black and white system using what was at the time an incredibly inexpensive per hour for the lines, while the system itself was ,000. In June of the same year, DARTnet had successfully connected a transcontinental IP network of over a dozen research sites in the United States and Great Britain using T1 trunks. Today, DARTnet has evolved into the CAIRN system, which connects dozens of institutions. CU-SeeMe revolutionizes video conferencing One of the most famous systems in the history of video conferencing was the CU-SeeMe developed for the MacIntosh system in 1992. Although the first version didn't have audio, it was the best video system developed to that point. By 1993, the MAC program had multipoint capability, and in 1994, CU-SeeMe MAC was true video conferencing with audio. Recognizing the limitations of MAC compatibility in a Windows world, developers worked diligently to roll out the April 1994 CU-SeeME for Windows (no audio), followed closely by the audio version, CU-SeeMe v0.66b1 for Windows in August of 1995. In 1992, AT&T rolled out their own ,500 video phone for the home market. It was a borderline success. That same year, the world's first MBone audio/video broadcast took place and in July INRIA's video conferencing system was introduced. This is the year that saw the first real explosion in video conferencing for businesses around the globe and eventually led to the standards developed by the ITU. International Telecommunications Union develops coding standards The International Telecommunications Union (ITU) began developing standards for video conferencing coding in 1996, when they established Standard H.263 to reduce bandwidth for transmission for low bit rate communication. Other standards were developed, including H.323 for packet-based multi-media communications. These are a variety of other telecommunications standards were revised and updated in 1998. In 1999, Standard MPEG-4 was developed by the Moving Picture Experts Group as an ISO standard for multimedia content. In 1993, VocalChat Novell IPX networks introduced their video conferencing system, but it was doomed from the start and didn't last. Microsoft finally came on board the video conferencing bandwagon with NetMeeting, a descendent of PictureTel's Liveshare Plus, in August of 1996 (although it didn't have video in this release). By December of the same year, Microsoft NetMeeting v2.0b2 with video had been released. That same month, VocalTec's Internet Phone v4.0 for Windows was introduced. VRVS links global research centers The Virtual Room Videoconferencing System (VRVS) project at Caltech-CERN kicked off in July of 1997. They developed the VRVS specifically to provide video conferencing to researchers on the Large Hadron Collider Project and scientists in the High Energy and Nuclear Physics Community in the U.S. and Europe. It has been so successful that seed money has been allotted for phase two, CalREN-2, to improve and expand on the already in-place VRVS system in order to expand it to encompass geneticists, doctors, and a host of other scientists in the video conferencing network around the world. Cornell University's development team released CU-SeeMe v1.0 in 1998. This color video version was compatible with both Windows and MacIntosh, and huge step forward in pc video conferencing. By May of that year, the team has moved on to other projects. In February of 1999, Session Initiation Protocol (SIP) was launched by MMUSIC. The platform showed some advantages over H.323 that user appreciated and soon made it almost as popular. 1999 was a very busy year, with NetMeeting v3.0b coming out, followed quickly by version three of the ITU standard H.323. Then came the release of iVisit v2.3b5 for both Windows and Mac, followed by Media Gateway Control Protocol (MGCP), version 1. In December, Microsoft released a service pack for NetMeeting v3.01 (4.4.3388) and an ISO standard MPEG-4 version two was released. Finally, PSInet was the first company to launch H.323 automated multipoint services. Like we said, 1999 was a very busy year. SIP entered version 1.30 in November of 2000, the same year that standard H.323 hit version 4, and Samsung released their MPEG-4 streaming 3G video cell phone, the first of its kind. It was a hit, particularly in Japan. Rather predictably, Microsoft NetMeeting had to release another service pack for version 3.01. In 2001, Windows XP messenger announced that it would now support Session Initiation Protocol. This was the same year the world's first transatlantic tele-surgery took place utilizing video conferencing. In this instance, video conferencing was instrumental in allowing a surgeon in the U.S. to use a robot overseas to perform gall bladder surgery on a patient. It was one of the most compelling non-business uses in the history of video conferencing, and brought the technology to the attention of the medical profession and the general public. In October of 2001, television reporters began using a portable satellite and a videophone to broadcast live from Afghanistan during the war. It was the first use of video conferencing technology to converse live with video with someone in a war zone, again bringing video conferencing to the forefront of people's imaginations. Founded in December of 2001, the Joint Video Team completed basic research leading to ITU-T H.264 by December of 2002. This protocol standardized video compression technology for both MPEG-4 and ITU-T over a broad range of application areas, making it more versatile than its predecessors. In March of 2003, the new technology was ready for launch to the industry. New uses for video conferencing technologies 2003 also saw the rise in use of video conferencing for off-campus classrooms. Interactive classrooms became more popular as the quality of streaming video increased and the delay decreased. Companies such as VBrick provided various MPEG-4 systems to colleges across the country. Desktop video conferencing is also on the rise and gaining popularity. Companies newer to the market are now refining the details of performance in addition to the nuts and bolts of transmission. In April of 2004, Applied Global Technologies developed a voice-activated camera for use in video conferencing that tracks the voice of various speakers in order to focus on whoever is speaking during a conference call. In March 2004, Linux announced the release of GnomeMeeting, an H.323 compliant, free video conferencing platform that is NetMeeting compatible. With the constant advances in video conferencing systems, it seems obvious that the technology will continue to evolve and become an integral part of business and personal life.
