Competency evidence is documented information showing that a person has the required knowledge, skill, training, qualification, or authorization to perform a defined task or role. In manufacturing, it commonly supports decisions about who may perform, inspect, approve, or supervise specific work.
Competency evidence may include training records, qualification sign-offs, skills matrix entries, practical demonstrations, assessment results, supervisor approvals, or records tied to controlled work instructions. In regulated or quality-sensitive environments, it is often linked to job roles, process requirements, product requirements, or customer-specific qualifications.
Competency evidence should not be confused with competence itself. Competence is the actual ability to perform the work; competency evidence is the record used to show how that ability was established, reviewed, or authorized. A general training record is one form of competency evidence, but it may not be sufficient by itself when a task requires process-specific qualification, certification, or documented authorization.
In audit and quality contexts, competency evidence helps demonstrate that work was performed by personnel whose qualifications were defined and recorded at the time of execution. For example, cross-training on an aerospace operation may require evidence that the operator was trained to the approved work instruction and authorized for that operation before performing production work.
