Training Matrix
A training matrix maps each person to the training their role requires and records, per requirement, whether it has been completed, the date it was completed, and when it expires, so that coverage and currency can be read for a team, a site, or an audit.
What It Is
A training matrix tracks obligations rather than abilities. Each role carries a set of required training items: procedures, certifications, refreshers, revision-specific briefings. Each person in the role is mapped to those items, and every cell holds a status derived from a trained date and, where the item is perishable, an expiry. The matrix answers a compliance question, "is everyone who must be trained on this trained, on the current revision, within the validity window?", and a scheduling question, "who is about to lapse?" It does not say how well anyone performs; that is the skills matrix's job. In regulated operations the two grids are kept deliberately separate and cross-referenced, because an auditor asks for both: proof that training occurred and proof that competence was verified. A matrix that stores only checkmarks, without dates and revisions, cannot answer either question once the procedure changes.
Key Facts
- Cells hold a status computed from a trained date and an expiry, not a manual tick: complete and current, complete but expiring, overdue, or not started.
- Requirements attach to the role; people inherit them when they take the role and shed them when they leave it.
- Perishable items carry a validity window; when a procedure revision is issued, the requirement can be re-opened for everyone assigned to it.
- The matrix reads from the same trained dates that a skill record carries, so one date serves training, currency, and the skills matrix.
- Coverage is judged per shift and site, not per organization: ten trained people on one shift and none on the other is a gap.
- Spreadsheet matrices fail on revision control and expiry math first; those two features are the usual reason to move to software.
The Three Matrices Compared
| Training matrix | Skills matrix | Competency matrix | |
|---|---|---|---|
| Unit tracked | A required training item per person | A skill at a proficiency level per person | A competency against its required level per role |
| Updated when | A completion is recorded or an expiry passes | An assessment is recorded | The framework or an assessment changes |
| Who reads it | Training, compliance, and shift supervisors | Team leads and resource planners | HR, L&D, and succession owners |
| The audit it satisfies | "Were they trained on the current revision, and is it in date?" | "Can they do the work, and who verified that?" | "Does the role's required standard exist, and who meets it?" |
How SkillsDB Models It
In SkillsDB training requirements attach to roles and certifications attach to skills, each person-to-skill record carrying a trained date and an expiry where the skill is perishable. The training matrix is generated from those records, flags upcoming expiries, and can re-open a requirement when a linked document or procedure is revised. See Certifications.
