At what point do you need to formalize process controls?

Work Instructions

Currently, I am in a business environment where a lot of proto typing is being conducted. My division is considered as a "spring board" to new technology. Often, new products are developed and then transitioned to production operation in another location. Currently, individuals in higher management positions feel that detailed process work instructions need to be in place prior to the first part being sold to a customer. At the same time I contend that these are "proto type" operations, subject to constant change. It would be very difficult to document every change in the proto typing operations.

My question is, at what point do you need to formalize process controls in the transition from prototyping to pre-production to production processes? At what point do you need to have all of your "I's" dotted and your "t's" crossed?

IMHO it is important to document every step and change in a proto-type process. The process, although it may change every day needs to reflect the changes and reasoning that went into every change. Once the process is ready for production, the procedure covering the process should go with it. Leaving the work instructions to be written in production is like turning your back on them. "Here, I made it now you figure out how to use it".

A fully documented proto-type process will save you countless time and money in development of future processes and will aid in continuous improvement projects on the processes you have already developed.

Any other opinions?

I agree with Dave. My work in engineering has always required a "book" relating to all of the activities that go on within the prototype process. A well documented protoype process will save time, dollars and a lot of headaches when the project goes to the floor. Been there, done that.

"Currently, individuals in higher management positions feel that detailed process work instructions need to be in place prior to the first part being sold to a customer."

I agree, in the automotive sector this method is called "PPAP", in the Government sector we called it "First article inspection/Test, Verification and Validation (V&V), among other things that I can't remember or is not printable.

Yup. Call it a project folder, whatever. It builds as you proceed. As pointed out above, the process should be well defined. The 'work instructions' point D.Scott made is a good one.

:) Look at the system as a way to track or make foot step. Factual information to keep things in line as well as keep things from reoccuring. Be able to the the story from beginning to end.
