How to Plan IT Support for a Business System With No Documentation

An undocumented system can become a support risk when its original developer or administrator is unavailable. Teams may not know where it runs, how to restore it, or which business processes depend on it.

What to check

Map users, business purpose, hosting, dependencies, credentials ownership, backup coverage, vendor contacts, and recent changes. Observe routine operations and interview users without making unreviewed production changes.

Recommended next step

Create a practical runbook for common support and recovery tasks, assign owners, and validate backups. Prioritize documentation by business impact and capture decisions as the system changes.
