Production - This type of project or process is often referred to as "Short Run" or "Production" work. This type of work includes tooling, special machines, and lower volume machining and assembly work.

Assembly/Second Operation - Is either prototype or production for manufacturing with additional assembly process requirements. Reference the assembly/second operation work instructions.

1 General

All personnel who are involved in prototype, production and assembly process are subjected to this procedure.
Engineering and Quality are responsible for providing any work instructions necessary to the production and acceptance process.

  • Quality shall monitor conformance to any work instructions.

  • Quality shall monitor conformance to any inspection procedures.

2 Documentation

All required master documentation is contained in the file folder in the office.
