Interpretation

The results of the SIPOC analysis will assist in proper definition of the project.
The process team should have representatives from each of the key customer
and supplier groups (collectively, the stakeholders). The inputs and outputs to
the process provide a check on the process map, and they can assist in project
scope definition, as well as general problem solving of sources of variation.

• To identify unnecessary movement of material or personnel

Methodology

Begin with a floor plan, layout, or map of the physical area used by the process.
Write a number 1 at the physical location where the process begins and then a
number 2 at the next physical location to which the material or personnel will
move. Draw a line from number 1 to number 2. Repeat for all subsequent
movements of the material or personnel.
