The Engineering Change Control system
tracks all the information about a part as it changes over
time and through versions. If you get a part returned from a customer
that was built three years ago and has now failed, then you can
answer the vital question "How did we make this then ?". What was the
current drawing, the bill of materials, routing, what version was it
at ? What was the Control plan ? What was the FMEA and what
Quality Plan and APQP were in effect and how can we be seeing
what we are seeing ?
You can build up your 'next' version with a complete set of new
drawings, plans and documentation recorded and waiting until you are
ready to switch the part to the new version. Engineering control
is fully integrated with Production Control so you can build 'back'
versions if you need to.
All documents, drawing, plans etc are stored using the
