Signal 1: critical knowledge lives in people’s heads, not in your planning system
When planners know exactly who has which skills, which certificates are about to expire, and which combinations work best, it can seem efficient. In reality, it’s a risk.
As long as that knowledge isn’t explicitly captured in the system, the organization becomes dependent on individuals. Absences, turnover, or growth make that painfully clear. Smart planning embeds that knowledge into the system itself — not to replace people, but to make expertise scalable and transferable.
