Skills Inventory
A skills inventory is the dated, per-person record of which skills each employee holds, at what proficiency level, on what evidence.

What It Is
A skills inventory is a structured record, one entry per employee, listing the skills that person holds, the assessed proficiency level for each, the method and date of assessment, and any supporting evidence such as a certification or a supervised sign-off. It is organized around the person, which distinguishes it from a skills matrix (organized around a team) and a skills database (organized around the organization). The inventory is the source the other two are built from: a matrix is a view of several inventories against a role's requirements, and a database is the queryable store of all of them over time. An inventory is only as useful as it is current. Because skills decay and roles change, each entry needs a reassessment date, and the inventory needs an owner responsible for keeping it accurate.
Key Facts
- Unit of record: one person, one skill, one assessed level, one date, one method.
- Minimum fields: skill (from the library), level, method, assessor, date assessed, reassess-by date, evidence.
- Three sources of ratings are standard: self, manager, and a verifying method such as a test or evidence.
- Spreadsheet inventories typically break past roughly 50 people, a second site, or the first audit.
- Currency is the main failure mode: an inventory with no reassessment dates is a snapshot, not a record.
- The inventory feeds the skills matrix, gap analysis, staffing searches, and succession slates.
Inventory, Matrix, and Database Compared
| Term | Unit of record | Owner | Update cadence | Breaks when |
|---|---|---|---|---|
| Skills inventory | Person × skill | Employee and manager | On assessment or evidence change | Nobody owns reassessment dates |
| Skills matrix | Team × required skills | Team lead or trainer | Per planning cycle | Teams exceed one sheet or one site |
| Skills database | Organization × all skills, over time | HR, L&D, or operations | Continuous | It is a spreadsheet pretending to be a system |
How SkillsDB Models It
In SkillsDB the inventory is the set of person-to-skill records, one per person per skill, whether the skill arrived through a Career or was added as an Additional Skill from the Skills Library. Each record holds three grades on the organization's 0 (N/A) to 5 scale, Employee, Manager, and Benchmark, and, where the career tracks training dates, a training date with its expiration status. A Payroll Specialist's record for Multi-State Tax Filing might read Employee 3, Manager 4, Benchmark 3, trained March 2026, Valid; the specialist sees exactly that row on their Skills page, and the manager sees it again on the team view and, for the whole population, on the skill detail page's Proficiency tab. Search reads the same records, so a resource planner can filter People by a skill, a minimum grade, an Expert flag, or a certification, within whatever scope their Search Permissions allow. Nothing is maintained as a separate list. See the Skills Library and Resume Search.
