What Is a Skill?
A skill is a specific, observable ability to perform a task to a defined standard, expressed with a proficiency level so it can be compared across people and over time.
What It Is
A skill is the smallest unit of capability an organization can name, measure, and develop. It describes something a person can do, not something they know about or a trait they have, and it is written narrowly enough that two assessors watching the same work would reach the same rating. "Configure a managed switch to site standard" is a skill. "Networking" is a category. "Detail-oriented" is a trait. The distinction matters because everything downstream depends on it: a skills matrix is a grid of skills, a gap is the distance between a required and an assessed skill level, and a development plan is a sequence of skills to raise. A skill without a proficiency level is only a label. Attached to a level and a date, it becomes a data point that can support staffing, succession, and compliance decisions.
Key Facts
- A skill is defined by three parts: the action, the object it acts on, and the standard it meets.
- The four working types are hard, soft, transferable, and perishable; a single skill can belong to more than one.
- Skills are measured on a proficiency scale, most often 0 to 5 or a four-step scale from awareness to expert.
- A skill set is the group of skills a role requires or a person holds, typically 6 to 12 per role.
- A skills library is the controlled list of skills an organization uses; free-text skills cannot be compared or aggregated.
- Every skill a person holds can carry a trained date: when they were trained, assessed, or last performed it. Trained dates are what a training matrix runs on.
- Perishable skills need a reassessment interval measured from the trained date; durable skills do not decay without practice in the same way.
The Four Types of Skills
| Type | Definition | Example | Decays without practice? |
|---|---|---|---|
| Hard or technical | Procedural or tool-specific ability with a testable outcome | Isolating a fault on a power distribution unit | Yes, moderately |
| Soft or behavioral | Observable interpersonal or judgment behavior | Running a handover so nothing is lost between shifts | Slowly |
| Transferable | Ability that holds its value across roles and industries | Scoping a project and controlling changes to it | Slowly |
| Perishable | Ability tied to a certification, revision, or currency window | Operating a specific chiller model under alarm | Yes, on a fixed clock from the trained date |
How SkillsDB Models It
SkillsDB treats skills as the base primitive: each skill lives in the organization's own library, carries a proficiency scale with anchored levels, and links to the roles that require it and the people who hold it. Each person-to-skill link also records a trained date and, where the skill is perishable, an expiry, so currency is a property of the record rather than a spreadsheet column someone remembers to update. Gaps, learning plans, the skills matrix, and the training matrix are all derived from those links rather than maintained separately. See the Skills Library.
