The Two Types of Maintenance SOPs

Type 1: Preventive Maintenance SOPs

PM SOPs define the correct procedure for each scheduled maintenance task — the steps to follow, the standards to check against, the measurements to record, and the escalation criteria when findings are outside acceptable ranges. These SOPs are delivered as PM checklists in QuipAssist, executed at the equipment via mobile QR scan, and completed in real time rather than retrospectively.

Content sources for PM SOPs:

• Manufacturer maintenance manuals — the baseline procedure for each task
• Experienced technician knowledge — the equipment-specific refinements and local conditions that manufacturer manuals cannot anticipate
• Regulatory and industry standards — required steps for compliance-critical equipment (fire suppression, elevators, electrical systems)
• Post-incident learning — steps added after failures reveal PM gaps that the original procedure did not address

Type 2: Reactive Repair SOPs

Reactive repair SOPs define the diagnostic and repair procedure for common failure modes — what to check first, what tools and parts to bring, what the repair method is, and what to verify before returning the equipment to service. These SOPs are built iteratively from documented repair history rather than designed upfront, because the most valuable reactive repair SOPs address the failure modes that actually occur most frequently in a specific operation.

Content source for reactive repair SOPs: Well-documented work order completions in QuipAssist — root causes, repair methods, parts used, and resolution approaches — become the institutional knowledge base from which repair SOPs are distilled. The AI Insights Chatbot surfaces which failure modes are most common: “What root causes have been identified most frequently for commercial refrigeration failures in the past 12 months?” — and those high-frequency failure modes are the first candidates for formal repair SOPs.

How to Build PM SOPs Systematically

1. 1

   Identify the Equipment Categories Needing SOPs

   Start with Tier 1 equipment (highest consequence) and the equipment categories with the highest reactive failure rates — these are the areas where standardized procedure provides the most value. Build SOPs for 3–5 equipment categories initially rather than attempting to cover the entire portfolio before launching.

2. 2

   Gather Manufacturer Documentation

   Collect manufacturer PM manuals for each target equipment category. These provide the baseline procedure content. For equipment without available manuals, request documentation from the manufacturer or an authorized service provider. Manufacturer documentation is the starting point — it gets refined by Steps 3 and 4.

3. 3

   Interview the Most Experienced Technician for Each Category

   A structured interview with the technician who best knows each equipment category surfaces the institutional knowledge that manufacturer manuals miss: this unit runs differently from others in this category, this connection point always needs extra attention, this vendor should be called for any problem with the controls system. This step is particularly urgent for technicians approaching retirement or known transition.

4. 4

   Build the Checklist in QuipAssist

   Convert the combined manufacturer + technician knowledge into a QuipAssist PM checklist: each step as a separate checklist item with the action, the standard or acceptable range, and the escalation criterion. Add reference photos for visual inspection items — taken at actual equipment in your facility, not generic manufacturer images. Configure required fields for any measurement that should be recorded rather than just checked.

5. 5

   Validate with a Field Trial

   Have a technician with moderate (not maximum) experience execute the new PM checklist on actual equipment while the experienced technician observes. Gaps — steps that are unclear, measurements that are difficult to take as specified, escalation criteria that are ambiguous in practice — surface immediately in field validation and should be corrected before the SOP is deployed broadly.

6. 6

   Deploy and Maintain

   Once validated, apply the PM checklist to all assets in the equipment category. Set a calendar reminder to review each SOP annually — and immediately when: a new failure mode is identified that the SOP did not address, a manufacturer issues updated maintenance guidance, or a regulatory requirement changes. SOPs that are not actively maintained become outdated and eventually harmful when they direct technicians to outdated procedures.
