Process Model Spec

Purpose

Specify a process model clearly enough that a UML activity diagram or BPMN model can be drawn consistently.

Use when

• a process must be visualised
• as-is or to-be work needs explicit flow definition
• actors, decisions, and outcomes must be clarified

Inputs

• problem context
• available evidence and constraints
• known stakeholders or actors
• desired output format

Procedure

1. Clarify the decision or deliverable.
2. State assumptions before analysis.
3. Apply the technique explicitly rather than implicitly.
4. Capture findings in a structured table or list.
5. Separate facts, inferences, and unknowns.
6. End with implications for next actions.

Outputs

• process narrative
• tasks/actors/decisions/outcome breakdown
• as-is or to-be model spec
• modelling assumptions

Guardrails

• Do not present the technique as the answer; use it to inform a decision.
• Flag missing evidence and weak assumptions.
• Keep terminology consistent with the project glossary.
• Where tradeoffs exist, rank them explicitly.

Completion criteria

• technique applied correctly
• assumptions visible
• findings actionable
• next step clear
