The problem

An established system had grown for years without an up-to-date design. Leadership needed to know what it actually did before deciding what to build next.

How I approached it

  1. Started from real usage data, not the old documentation
  2. Parallel agents wrote sections, then a consistency editor and a gap auditor checked the whole

What was built

  • 44 business processes mapped in BPMN
  • 644 endpoints assessed
  • A 16-context target design with 76 open decisions listed for leadership

Stack

  • Enterprise architecture
  • BPMN
  • Domain-driven design

Outcomes

  • A shared, accurate picture of the system
  • Decisions made explicit instead of assumed
