A shared model before a software decision
Process mapping turns an informal sequence of tasks into a reviewable description of work. Start with a trigger, define the accepted outcome, and identify the person or system responsible for each transition. The most useful map explains waiting, rejection, correction, and cancellation as clearly as the successful path.
Keep the first map small enough to review with the people doing the work. A supplier approval, document intake, or image publishing flow is a better starting point than an entire department. Separate the current process from the intended future process so assumptions do not quietly become requirements.
What to capture for each step
Record the required input, accountable role, decision rule, output evidence, and exception owner. A box labeled “approve” is incomplete until the team agrees who can approve which version of the input. A box labeled “send” needs a definition of what happens when the destination accepts the request but its response is lost.
Use ordinary flowcharts for simple discussions and a formal notation when the audience or tooling requires it. Notation should help the team explain its decisions, not hide uncertainty behind more symbols. Version the map alongside the requirements that it informs.
Turn a map into an implementation brief
Describe the states that matter to the business separately from worker activity. A document can be awaiting approval while a notification worker retries. Those are different kinds of waiting and should not be represented as the same failure.
Attach representative examples to the map. Include a normal submission, missing information, a duplicate event, a late approval, and a changed input. Write the expected outcome for each before choosing endpoints or queue technology. These examples become useful acceptance tests.
A practical first deliverable
Produce one reviewed diagram, a short data dictionary, a transition table, and an unresolved-questions register. Identify the process owner and the evidence needed to declare a pilot successful. Then automate one narrow transition while preserving a documented manual fallback.
The process automation guide picks up where the map ends. For an interface-oriented view, explore the business process API guide. The goal is a system whose behavior follows an agreed process, rather than a process that has to bend around an unexplained script.
