Engineering change approval workflow

This engineering change approval workflow gives plant teams a visible route from a change request through impact assessment, safety review, operating approval, implementation, and closeout. It distinguishes work that has a safety impact from routine changes and also separates outage work from changes that can be completed while equipment remains available.

CASE ANALYSIS

Scenario

A plant needs a controlled route for equipment or process changes that may affect safety, production, or documentation.

Key decisions

  • Incomplete packages return to the requestor.
  • Only changes with safety impact route to EHS.
  • The asset owner accepts the operational change.
  • Outage work requires a schedule and permit.
  • Commissioning includes updating controlled drawings.

When to reuse this

Use this pattern for management-of-change workflows in industrial facilities. Hazard review and permit requirements should reflect the site’s safety management system.

FAQ

Why route safety changes to EHS?02
EHS can assess hazards and confirm required controls before authorization.
When is an outage plan needed?03
It is needed whenever implementation requires equipment isolation or interruption of service.
