The same facts as the technician list, asked from the other end. The skills matrix ## Why it is a separate screen The technician list answers *"what is Raj able to do"*. The matrix answers *"who else can do this when Raj is on leave"* — which is the question that decides whether a plant can cover a shift. A per-person list can never answer it. The reader would have to hold five rows in their head to see the gap, and gaps found that way are found late. ## Reading it Skills down one axis, people across the other. A filled cell means that person holds that skill. What you are looking for is a **row with one mark in it**. That is a skill one person holds, and the day they are away is the day work needing it stops. ## What to do about a thin row * **Train somebody.** Training courses are configured under [workforce settings](/config/workforce). * **Cover it by contract.** A [vendor](/commercial/vendors) with that capability is cover, if a contract is in place before you need it. * **Know about it.** Sometimes one person is the honest answer — but it should be a decision, not a discovery. ## Certifications Certifications show alongside skills, with their expiry. A certification about to lapse is a row about to get thinner, which is why expiry warnings arrive early rather than on the day. ## Keeping it accurate The matrix is only as good as what is recorded on each person. Skills and certifications are set on the [technician](/workforce/technician-detail), and configured as a list under [workforce settings](/config/workforce). ## Related topics - [Workforce settings](/config/workforce.md) - [Inside a technician](/workforce/technician-detail.md) - [Statuses and transitions](/config/statuses.md) - [Inside a vendor](/commercial/vendor-detail.md) - [Maintenance plans](/maintenance/plans.md)
