Work Order vs Service Request: The Difference That Keeps Your CMMS Clean

Key takeaways

• A service request is an unscreened ask for help from anyone on the floor.
• A work order is approved, planned, resourced work.
• Keeping them separate lets you triage demand before it clogs the maintenance schedule.
• Collapsing the two floods the CMMS with noise and hides real planned work.

Short answer: A service request is anyone asking for help — unscreened demand. A work order is work that has been reviewed, approved, planned, and resourced. Keeping the two as distinct stages lets you triage and prioritise before anything hits the schedule. Treating every request as a work order buries planned work under noise.

What a service request is

• An unscreened ask from operators or other departments.
• May be duplicate, vague, or non-maintenance.
• The intake funnel, not the schedule.

What a work order is

• Reviewed and approved work.
• Planned, with parts and labour assigned.
• The unit maintenance actually executes and measures.

Why the gate matters

The screening step between request and work order is where duplicates merge, priorities get set, and non-maintenance asks get redirected. Without it, the schedule fills with noise and planners lose control.

What good intake looks like

• Easy request capture for the floor.
• A planner gate that converts valid requests to work orders.
• Clear status so requesters see progress.

How OEE relates

Fast, clean intake of breakdown requests shortens response time and protects Availability. A clogged, undifferentiated queue slows the fixes that matter most.

Frequently asked questions

Are they the same record?

No — a request becomes a work order only after approval.

Who converts a request?

A planner or supervisor at the screening gate.

Why not skip requests?

You lose triage and the schedule fills with noise.

Does this affect uptime?

Yes — clean intake speeds breakdown response.
