The skills matrix: the one chart a plant head should read every week.
A line can be at full headcount and still have one person standing between a critical tool and a stopped night shift.
In brief
- Count certified people per tool per shift, not heads.
- One or none on a shift is a single point of failure.
- The matrix is also the training plan.
- Review it weekly; attrition changes it without warning.

How to read it
Look across a row for a tool that is strong on day shift and thin at night. Look down a column for a shift that depends on one person for several tools. Both are where a single resignation turns into lost output.
Build one in five steps
- List tools and tasks. Run, assist, maintain, qualify.
- Define certification. What someone must show before signing off alone.
- Record who holds what, by shift, with dates.
- Set a minimum per cell, higher for bottleneck tools.
- Turn the gaps into the training and hiring plan.
