Utilities coordinate field work, suppliers, and internal reviewers across large operations. Signed records help establish the source and version of the evidence each team receives.

## Electricity & water utilities: Record the evidence behind maintenance sign-off

A completed work order may lack a clear connection to its inspection documents.

### What to record

Link the asset and work-order references, evidence fingerprints, contractor source, and authorized review outcome in signed records.

### What to review

Compare the reported work with its approved scope and verify condition through the utility’s established inspection process.

### The outcome

A maintenance history that preserves the basis of a recorded sign-off.

## Renewable energy: Keep project reports tied to source evidence

Project reports summarize measurements and contractor statements from several sources.

### What to record

Record the report fingerprint, measurement references, method version, submitting team, and review event.

### What to review

Check the published version and assess the underlying measurements through qualified technical review.

### The outcome

A traceable report package for the project team and authorized stakeholders.

## Utility supply networks: Review a supplier’s approved document package

Technical and procurement teams can receive different revisions of supplier submissions.

### What to record

Create a signed manifest of supplier document fingerprints, specification references, and the recorded assessment outcome.

### What to review

Compare later submissions with the reviewed package and route changed specifications back to the responsible team.

### The outcome

A shared reference for the documents used in a supplier review.

## Before you begin

Begin with administrative evidence and approved maintenance records. Operational control, safety decisions, and measurement validation remain in qualified systems and teams.
