Thanks for the input. I read that several times before I posted. Am I on track by saying CM is nothing more than document and record control, redeveloping the control plan or heat treat processes, notifying proper parties, proper first article inspection, and then monitoring the change for proper validation. I think I am trying to overthink this a bit too much.
Close, but not quite. The folks in aerospace and electrical engineering (somewhat in software) make a big deal out of compatibility with ALL Associated Dociuments (read Processes, such as interchangeability; inspection tools, instruments, tolerances; etc.)
For example, if you heat treat widgets for customer A and also heat treat gizmos to the same spec for Customer B, do they both fit in same pan or rack? Same dwell time? Does either customer have a requirement to keep Rockwell points away from certain area of the part?
The customer -specific instructions and requirements are part of the so-called Associated Documents. Depending whether you use gas or electric furnace, is there any fluctuation in energy supply which might affect your process? (I recall an instance in the 60's when the local gas company in Long Island City suddenly began delivering gas with a lower BTU per cubic foot than previously, without notice, causing a lot of fouled up heat treating for at least one company.)
My consistent thesis is good
CM requires the input of a person knowledgeable about all the possible "What ifs" which can affect the organization's product or service and makes provision to check the interactions if any one of the factors fluctuates or changes. I do not think it is a "clerk job."
