Although some companies try to do business in series, it is not desirable. The processes overlap almost totally.

For example, the product specification should be created and released very early in the product lifecycle. The product specification should be put under a simplistic form of change control, then, long-lead parts should be released in lead time. This may well be done long before a BOM is structured. Some documents may be obsolete before they are released, thus the processes should not be considered serial, but very parallel.
In fact, trying to do these processes in series creates a problem. Shall we hold up the project until all the items are documented before releasing the long-lead items? Shall we wait for their assemblies to be released? Grouping any of the documents for release creates an artificial batching of the work. It is much better to design the processes to encourage an item-by-item release in lead time to produce, since that is the way they are needed and used.
The real beginning of CM occurred when Eli Whitney designed and built his cotton gin with interchangeable parts. That concept of interchangeability has come to be expected in all product manufacturing. Items that are replaceable service items and the end product are expected to interchange, or reasonable notice be given. Many companies use CM standards and practices that date back to the early years of their conception.
Industry standardization of certain CM practices began with the government during the space program in the late s. This was a necessary and natural occurrence, since the assurance of interchangeability between the many contributors in a space program was very important. In the late s, the Department of Defense DOD recognized that each agency and branch was developing its own set of standards. In the s and in the twenty-first century, software solutions have been sought to solve every problem.
The following quote from the first edition of this book is no longer true: Industry by and large, however, has been satisfied to let the DOD take the initiative. The result is an IRS like, bureaucratic maze of forms and regulations. It is time for the commercial CM world to stand up and be counted. Several organizations have helped the discipline. However, a lack of understanding of the basics still exists.
This book will answer the challenge and keep it simple — that is the goal! Let us examine the CM organization starting with the names it is called — the organizational names that is. The terminology varies depending upon the company.

Some common names are:. Documentation Control may be a proper term, if that is all the function does. There may be several documentation control functions in the company or division — engineering, manufacturing, service, etc. One of these functions normally engineering should be designated as the CM function — it will control the total processes by which all do business as well as other functions.
The CM title is preferred when the responsibilities are generally as outlined in this book. Presuming that your company or division organization is slim few total levels of management , the CM function should answer to the VP of engineering. In larger organizations there may be an engineering services function between CM and the VP of engineering. If the function reports to any lower in the organization, it will not have the necessary clout; communication of needs will suffer, and the result will be more of the symptoms described earlier.
Some companies have the CM function answer to quality assurance QA , manufacturing, operations, or even rarely to the president.
If the results are very good, do not change the reporting relationship. It can and does work well or poorly in any organization. Most companies have the function answer to engineering. The question is often asked, Isn't that like having the fox watch the chicken coop? The answer is, Of course, but they're engineering's chickens!

We are talking primarily about design documentation! If engineering has the function and the described symptoms exist, reorganization may or may not solve the problems. The design engineering management, however, runs the risk of losing the function if they eat too many chickens. Location of the function in QA tends to produce rigid over control.

No matter which organization has CM, there is always a risk that they will grind their own axe. Large multi-plant companies should have a CM organization in each business unit or division. They should also have a slim corporate function to ensure that minimum standards are met.

This minimum level of standardization should be based upon three criteria:. The greatest difficulties arise when engineering is in one location and manufacturing is in another or several different locations. A different building, across town, across the country, across an ocean … the bridge gets longer. When one of the manufacturing locations is offshore, this adds another level of complication. The ideal results are more likely obtained when the engineering or at least the continuing or sustaining engineering function , CM, and the manufacturing functions are in the same location small business unit.
This is desirable, regardless of the company size.
Within a business unit, placing CM responsibilities within multiple project offices is inviting chaos. This action might not be possible to undo. Are you sure you want to continue? Upload Sign In Join. Home Books Science.

Summary In this new edition of his widely-used Handbook, Frank Watts, widely recognized for his significant contributions to engineering change control processes, provides a thoroughly practical guide to the implementation and improvement of Engineering Documentation Control EDC , Product Lifecycle Management and Product Configuration Management CM.
Solid, pragmatic ideas for real product and process cost reduction. This may be good for quickly learning, but it will only take the reader so far. Watts imparts the same information, but invites the reader to think and to consider strengths and weaknesses of processes and procedures. The copious examples, illustrations and breadth of topics covered make this book "the" reference on EDC and CM.
