Hi Dave;
I have no quibble with your quibble. Jobs or roles should be derived from and serve the wider process(es). Still, not all companies have truly embraced process (flow) or they have adopted it in it's most bureaucratic form (think ISO). "Understanding the Job" actually means "Understand the System" (functional or dysfunctional) Rummler and Brache have some great tools for doing just that as you have eloquently posted on in the past.
