Business Logic Buried in .cfm Files: How to Document It Before Your Developers Leave

Decades of ColdFusion applications have business rules — pricing formulas, eligibility checks, approval workflows, tax calculations — embedded directly in .cfm and .cfc files, often with no documentation outside the developer's head. When that developer leaves, the knowledge leaves with them, and you're left reverse-engineering critical logic under pressure. The fix is a deliberate, layered documentation effort before they go: (1) auto-generate API documentation from your codebase using ColdFusion-native tools like DocBox (the maintained successor to Mark Mandel's ColdDoc) by adding CFCDoc / JavaDoc-style @hint comments to your components and functions; (2) capture the business logic that code can't explain — the "why," the edge cases, the tribal rules — in a structured knowledge base through targeted interviews and decision-table documentation; and (3) make it durable with a developer-exit knowledge-transfer process. This guide gives you the practical playbook and the exact CFML tooling.
