Maintenance Approval Workflows: When You Need Them and When You Don't

The approval problem

Every maintenance manager has been on both sides of this. You've had a tech buy a $2,000 part without checking with anyone — and you've had a machine sit idle for three days while a $50 work order waited for someone to click “approve.” Both situations are frustrating. Both are preventable. The trick is knowing which work orders need oversight and which ones just need to get done.

The root question is simple: does requiring approval on this work order prevent a bigger problem than the delay it creates? If the answer is yes, add the approval. If not, let your team work.

When approvals add real value

There are legitimate reasons to require approval on certain maintenance work. Here are the situations where it genuinely protects your operation:

High-cost repairs. Any work order that exceeds a dollar threshold — say $500 or $1,000 depending on your budget — should require manager approval. This isn't about trust. It's about visibility. You need to know when significant money is being spent so you can evaluate whether the repair makes sense versus replacing the asset.

Outside contractor work. When a work order involves bringing in a third-party contractor, approval ensures someone has vetted the scope, gotten a quote, and confirmed the contractor is qualified. Without this gate, you end up with surprise invoices.

Safety-critical equipment modifications. Anything that changes how a machine operates — rewiring, guard modifications, control system changes — needs engineering or management sign-off. This isn't bureaucracy. It's liability protection.

Compliance-driven work. In regulated industries (food production, pharmaceuticals, aviation), certain maintenance activities require documented authorization before work begins. This is a regulatory requirement, not a management preference.

When approvals are just friction

Here's where most teams go wrong: they require approval on everything because it “feels responsible.” In practice, blanket approval requirements create these problems:

• Routine PMs get delayed. If a tech needs approval to change a filter they change every 30 days, you've added friction to a task that should be automatic. The PM was already approved when you set up the schedule.
• Emergency repairs wait. A machine is down, production is stopped, and the work order is sitting in someone's inbox. The approver is in a meeting. The cost of waiting dwarfs whatever the approval was supposed to prevent.
• Techs work around the system. When approval is required for everything, techs stop submitting work orders and just do the work. Now you've lost visibility into what's happening — the opposite of what approval was supposed to provide.
• Managers become rubber stamps. When you approve 50 work orders a week and 48 of them are routine, you stop reading them. The two that actually needed review get the same 2-second glance as the rest.

A practical approval framework

Here's a framework that works for most small maintenance teams:

No approval needed: Routine PMs, low-cost corrective work (under your threshold), and emergency repairs on critical equipment. These are pre-authorized by the PM schedule or by the nature of the emergency.

Approval required: Work orders above your cost threshold, outside contractor engagements, equipment modifications, and any work in regulated areas that requires documented authorization.

Post-completion review: Instead of approving before work starts, review completed work orders weekly. This gives you visibility without creating delays. If you spot a problem — an expensive repair that should have been a replacement, a recurring fix that indicates a bigger issue — you address it in context rather than holding up the work.

How to set up a simple approval process

If you're implementing approval workflows for the first time, keep it simple. Complexity kills adoption.

1. Set a cost threshold. Pick a dollar amount that represents a meaningful expense for your operation. For most small shops, $500–$1,000 is reasonable. Anything below that threshold flows without approval.
2. Designate one approver. Not a committee. Not “the maintenance manager or the plant manager or the owner.” One person who is responsible for reviewing and approving work orders that hit the threshold. Add a backup for when that person is unavailable.
3. Set a response time expectation. Approval means nothing if it takes 48 hours. Establish a 4-hour SLA for approval decisions. If the approver doesn't respond within that window, the work order auto-escalates or auto-approves.
4. Make it mobile. If the approver has to log into a desktop application to approve work orders, it won't happen fast enough. Push notifications and one-tap approval from a phone eliminate the bottleneck.
5. Review and adjust quarterly. After 90 days, look at how many work orders required approval and how many were actually declined. If you're approving 98% of them, your threshold might be too low. Raise it until you're only seeing work orders that genuinely need a decision.

The approval anti-patterns

Watch out for these signs that your approval process has gone off the rails:

• Approval queue backlog. If you regularly have 10+ work orders waiting for approval, the process is broken. Either too many things require approval or the approver isn't keeping up.
• Techs delaying work order creation. If techs batch their work orders at the end of the week instead of creating them in real time, they're avoiding the approval process. That means it's too cumbersome.
• Emergency overrides are common. If people regularly bypass the approval process for “emergencies,” the process doesn't match reality. Redefine what actually needs approval.

Bottom line

Approval workflows exist to prevent bad decisions, not to slow down good ones. Build your process around the specific risks you're managing — budget control, contractor oversight, compliance documentation — and leave everything else alone. Your techs will use the system because it doesn't get in their way, and you'll have real visibility into the decisions that actually matter.
