✦ Synopsis
It is clear that quality control and sampling inspection are alive and well. This workshop is a testimonial to its resurgence. I think that Gary McDonald has assembled an excellent program and the speakers were exceptional. Both Ed Wegman and Seymour Selig deserve a great deal of credit for supporting this endeavor.
I will now turn to the lessons some of us may have learned. Naturally, I cannot speak for you, but I can describe what I gleaned from this conference. The first lesson that I learned is that it is useful to be an editor of a series of professional books since several speakers have informed us of their involvement, and evidently this is a good forum from which to advertise. The next thing that I learned is that you never agree to summarize what was accomplished at a workshop because it keeps you up the night before your presentation. Besides, it made me so attentive during the meeting that I was afraid to sneeze in fear of missing a pearl of wisdom. Finally, after listening to the papers and the ensuing discussions, I want to reaffirm my faith in the principle of "KISS" for quality control and sampling inspection. You might ask what is KISS: It is the acronym for "Keep it simple stupid." If new procedures are to be used in the real world, they had better be relatively simple, or somehow they will be lost. All of the procedures discussed at this workshop that are being implemented exhibit this quality.
In order to summarize, with a broad brush, the contents of the workshop, I will show you the fruits of last night's work. I must emphasize that I used the term "broad brush" because there is no way of doing justice to each of the excellent papers presented in the time allotted for this presentation.
We discussed three military standards at this workshop: We talked about MIL-STD-414, MIL-STD-781, and MIL-STD-105D. I would like to comment quickly on MIL-STD-105D. This standard is a sampling inspection system, and all of its facets, e.g., tightened and reduced inspection, must be used collectively if it is to be a meaningful document. Talking about the operating characteristics of a single plan does not capture the use for which it was intended.
We now turn to MIL-STD-414. It is clear from the discussion that this standard is badly in need of revision. It has been at least 25 years since it was written and times have changed. MIL-STD-lO5D has been revised several times, but 414 has not been touched. A little of the history of 414 is in order. Many of the original decisions made were guided by the desire to have 414 conform to 105B, the then current version of 105. Several definitions and procedures in MIL-STD-414 that matched 105B, such as
