Brown paper analysis seems to be a standard term for a working analysis of a set of interconnected procedures for a job or a project.

This example is useful:
An advisor from PCE Systems started working with the company in
January 2003 on a “Business Support Program” as pioneered by the
Institute for Independent Business. This involves spending typically two
days per month with the company on whatever issues the company faces.
One of the early actions taken was a “Brown Paper Analysis”, which looks
at the procedures in place within the organisation.
Copies of all the standard forms and documents were collected and stuck
on to a large roll of brown paper (as used by shopkeepers in earlier times
to wrap purchases). These forms were linked together to form a flow
diagram showing how enquiries were processed through the company
right up to post-sale customer care.
