How to build a skills matrix for your team

A skills matrix is one page that shows what a team can actually do. It is useful for the same reason it is uncomfortable: once the gaps are on a grid, they stop being a feeling and become a decision about hiring, training or waiting.

Choosing the skills

Between fifteen and twenty-five skills is the working range. Fewer and the matrix says nothing; more and nobody fills it in. Mix the technical skills with the ones people call soft and with the business knowledge that is usually assumed, and choose them against what the team will need next year rather than what it did last year.

Then a scale from zero to four, with a described behaviour at each level: none, beginner, intermediate, advanced, expert. The descriptions are the whole exercise. Without them, advanced means whatever the person filling in the form thinks it means, and two teams cannot be compared.

Filling it in without turning it into an exam

The hybrid approach works best: the person rates themselves, the manager reviews and adjusts, then there is a calibration conversation before anything is recorded. The order matters, because starting from self-assessment surfaces the skills a manager did not know someone had.

Expect the first version to be wrong in visible ways: everyone rating themselves a three, or one team scoring systematically higher than another. That is information too.

Using it

The gaps come in three shapes. Skills the team needs and nobody has. Skills one person has, which is a single point of failure with a name. And skills that a project starting next quarter is about to require.

Each gap closes in one of four ways: hire, train, contract, or partner with another team. Deciding which one is the actual value of the matrix; the grid itself is just the input.

Update it quarterly. A skills matrix that is refreshed once a year describes a team that no longer exists.
