From Code to Requirements: Agentic Reverse Engineering of Business Rules at Enterprise Scale

An AI workflow described in From Code to Requirements reconstructs business requirements from an enterprise system's code, tests, configuration and existing documentation. Seven specialized agents identify user journeys and business rules, with software-analysis tools and human review at designated escalation points. The authors report producing requirements documents in under nine minutes per service in one enterprise deployment, with extracted rules corroborated against production defect records. That result concerns recovering documentation from an existing system. The paper's much larger cost-reduction claim uses a modeled labor baseline, so it should not be read as a measured 98% saving on an otherwise identical completed migration.
