The question is, what actually happens in your organization? In what order do the practical steps in your operations occur? What depends on what? There is probably a formal or theoretical understanding of the way the operations are supposed to function or were planned to function.
These steps may be documented via procedures or the business plan. However, many times the original theoretical workflow gets eroded with actual practice and the real steps and dependencies go on working with little or no supporting documentation. A map of your workflows can be an invaluable tool to help prevent and solve business process issues and time consuming inefficiencies.
