Availability changes by time
A tool can be physically in the store at 09:00 and still be a poor choice for a job beginning tomorrow if calibration expires during the expected use window.
Tool readiness needs a timeline: current custody, expected return, scheduled calibration, equivalent capacity, and upcoming work demand.
Equivalent tools create resilience
Many maintenance tasks require a valid tool of a type, not a specific serial number. A readiness layer should show whether an equivalent valid tool can cover the job.
This helps managers avoid duplicate purchases while still seeing shortages early enough to act.
The pilot metric is simple
For a first implementation, readiness success is not an advanced forecast. It is fewer searches, known holders, valid calibration, and fewer surprise shortages.
That narrow proof is more valuable than a broad planning system that never reaches the tool counter.
