Nobody Knows What Dave Built
TL;DR: If your business depends on software that only one employee understands, you have a business continuity problem disguised as an app.
Dave built something useful. Maybe it automates quotes, moves customer data between systems, generates reports, or replaces the spreadsheet everyone hated. Great. The problem starts when Dave becomes the documentation, support desk, security model, and disaster recovery plan. AI-assisted coding makes it easier than ever for one capable person to build surprisingly important software without much oversight. Once other people depend on it, that little side project has become infrastructure. You don't necessarily need to rebuild it. You do need to know what it does, where the data goes, what it depends on, who can maintain it, and what happens if Dave wins the lottery tomorrow.
