Maintenance teams | Inzonex | 28 August 2026

A training list does not tell you which tasks have current assessment records when someone is away. Compare six maintenance task families across four team aliases, with evidence references, review dates and a separate coverage target.

Record coverage, not a competence score. No qualification, work authorization, safe staffing level or hiring decision is inferred. Use aliases and non-sensitive evidence IDs; keep actual personnel and assessment documents in your approved system.

Assessment record

No default review interval is prescribed. Use the dates set by your assessment process.

One absence can change the record picture

Fictional example: assessed records, current records and current available records differ across six maintenance tasks. Not observed workforce data.
Original fictional example, 28 August 2026. One alias is unavailable, and selected records have missing evidence or past review dates. These counts do not measure real people or establish competence.

Six task families, with a traceable starting point

The task families below adapt six selected tasks from the US O*NET occupation Maintenance and Repair Workers, General (49-9071.00). They are not a complete job description or a list of qualification requirements. Evidence examples and the four-alias layout are Inzonex editorial additions. Equipment, procedure revision, jurisdiction and assessment standard still need to be specified in the source record.

The counting rule

For each task, count an alias only when status is Assessment recorded, the evidence reference is non-empty, the assessment date is no later than the as-of date, the review-due date is no earlier than the as-of date, the dates are in order, and the alias is marked available. The review-due date itself counts as current. Missing dates are not treated as unlimited validity. A future assessment does not count.

Coverage gap = max(0, chosen target - counted aliases). A target of zero means no coverage target has been set for that row. The same person may appear under several tasks; this worksheet does not model simultaneous assignments, shifts, workload or supervision capacity. A missing or excluded record does not prove inability.

Training, competence and authorization are different records

The UK HSE competence guidance describes competence in terms of training, skills, experience, knowledge and their application, with requirements proportionate to the work. That is contextual guidance, not a US qualification rule. A course-completion entry alone cannot establish that a particular person can safely perform every task in this matrix. Site-specific risk assessments and work permissions remain separate.

Downloads and data handling

The matrix code performs calculations in this browser tab and does not send the entered records to an application API or save them in browser storage. Closing or reloading the page discards unsaved entries. Downloaded files contain what you entered and should be handled under your own information policy. The page retains the site's ordinary analytics; this is not a confidential personnel system. CSV formula-leading text is prefixed with an apostrophe for spreadsheet safety. JSON files retain the original text.

Skills matrix questions

Is a completed skills matrix proof of competence?

No. A populated cell is a record entered by a user, not an independent assessment. Competence depends on the task, workplace, training, experience, knowledge and ability to apply them. This worksheet does not verify qualifications, certify a person or authorize work.

Why can an assessed record still be excluded from coverage?

The counting rule also requires an evidence reference, an assessment date on or before the selected date, a review-due date on or after it, and availability of the person. A missing or past-due record is a documentation gap, not proof that a person lacks the skill.

Can I use this as an Excel skills matrix template?

Yes. The blank CSV contains six task families for four aliases, plus fields for status, evidence reference and review dates. The calculated CSV includes the entered records and exclusion reasons. CSV files contain values, not live formulas; changes made in a spreadsheet will not recalculate the exported coverage.

Does the coverage target set a safe staffing minimum?

No. The target is a user-selected planning value from zero to four. It is not a legal staffing requirement, a risk assessment or a recommendation about how many people can safely perform a task. Equipment-specific authorization and local requirements must be managed separately.
