A Process-based auditing course being offred by ASQ refers to a "simple four-box" process model.
I would appreciate any light you could shed on what that is and how it is used.

Who knows? They're probably putting a new wrapper on an old product.

Save your money and obtain a copy of ISO 19011. 19K11 is based on the Plan-Do-Check-Act process. It has a couple of minor flaws like not specifically telling how to interview, but I'll guarantee you the "4-box" is based on what it suggests.

Essentially figure out what you need to know, how you can find it out, what you are to do with the resulting information, and if something doesn't happen correctly....fix it!

Any thoughts from others about --> "simple four-box" process model ?

Randy is probably right - "...Probably putting a new wrapper on an old product..." But which one?

Here's a guess:
XXXXXX XXXXXXXXXXXX XXXXXXXXXXXXX

Input X -----> X Process X X Output X

XXXXXX XXXXXXXXXXXX XXXXXXXXXXXXX

^

!

XXXXXXXXXXXX

X Method,
Manpower X
Machinery

XXXXXXXXXXXX


The point would be - in organizing your audit, analyze the process this
way to make sure that you've considered each of the ingredients.

The top 3 boxes I am almost certain of. The contents of the "4th" box
are subject to opinion. You could also include measurement criteria,
timing, efficiency...

Sorry about the half-a$*%ed diagram. These were supposed to be 4 boxes,
with the lower box in the center of the diagram.

:o

Not knowing what the ASQ 4 boxes include, I also use 4 boxes like Brad.

The fourth box however is the feedback from either output or process to improve the process and/or the inputs.

Best regards,
