Process Flow Chart vs. Process Flow Diagram? Pages 38-39 in the APQP Manual

AirAusquin · Aug 28, 2007

Hello again. While studying the Control Plan form at pages 38-39 in the APQP book, the question arose.

Description for field 15 (Part/Process Number) mentions the Process Flow Chart
Description for field 16 (Process Name/Operation Description) mentions the Process Flow Diagram

It is this just a lack of homogeneity by the writers of the APQP book or there are really subtle differences that make a Process Flow Chart different than a Process Flow Diagram?

I am aware that process flow chart/diagram/description/whatever can have many variations/forms/styles/etc. Additionally, my language is Spanish so we end up with all kinds of translations for technical names in our industries.

Thanks again for your brilliant site!

I use them interchangeably. I very seldom use the term "chart". It is called a Process Flow Diagram (PFD) in my documentation and both columns of the Control Plan are covered in the PFD.

The only difference I can think there might be is that the Process Flow Chart may not employ extra verbiage that might be included in a Process Flow Diagram (for instance: the Delphi format for the Process Flow Diagram includes columns that point out the product and process characteristics produced and monitored at each process step. However, it also includes the two columns you mention.)

Help any???

Thanks Bill!
The basic difference you point out is what I had in mind.

I was not familiar with the Delphi PFD format. I searched the attachements list and didn't find an example. A google search didn't help neither. (I finally found it at the suppliers site)

Thanks again
