Reviving the Process Map

摘要

Perhaps this column has provided motivation and a call to action for the Six Sigma practitioner to revive the process map and use this simple qualitative tool to extract information and guidance not present in a basic flowchart. A set of starting categories useful for identifying input variables was presented, and an input variable classification scheme was suggested. The process map was reconnected to the fundamental equation of Six Sigma: Y = f(X). Additionally, input and output variables identified on a process map were analyzed in the context of a bounded process.
