Buyer guide
The predictive-maintenance pilot trap
A pilot can produce accurate alerts and still fail commercially. The real test is whether a trusted signal becomes completed work, verified risk reduction, and a repeatable operating process.
Why promising pilots stall
Teams often measure the easiest visible output, such as alerts or sensor coverage. Those measures do not prove that the organization changed a decision or avoided an economic consequence.
- The pilot monitors assets that are easy to instrument rather than assets with important failure consequences.
- Alerts arrive without a failure mode, confidence level, urgency, or clear next action.
- Maintenance planners cannot convert the recommendation into approved work at the right time.
- The CMMS, production schedule, parts process, and technician workflow remain disconnected.
- The team records avoided cost without a counterfactual, evidence trail, or finance-approved method.
The operating scorecard
The scorecard should follow the signal through the workflow. A high alert count can indicate poor tuning. A low alert count can be correct if the system is focused on rare, costly failure modes.
- Eligible asset coverage: critical assets and failure modes that the method can actually detect.
- Actionable alert rate: alerts that contain enough information to support a decision.
- Useful lead time: time between a trusted warning and the last practical intervention window.
- Work conversion: accepted recommendations that become scheduled and completed work.
- Verification rate: completed interventions checked against inspection, component, or operating evidence.
- Program economics: verified gross value minus software, hardware, labor, integration, and change costs.
A defensible ROI method
Begin with the affected event, not the vendor's general calculator. Separate hard savings, capacity value, risk reduction, and learning value because finance will not treat them equally.
- Gross event value equals avoided downtime, avoided damage, avoided emergency labor, and avoided expedited parts, with overlap removed.
- Realization equals gross event value multiplied by technical confidence, intervention completion, and the share of value the plant can actually capture.
- Net value equals realized value minus recurring program cost and one-time implementation cost.
- Use a range and show the baseline, evidence, assumptions, owner, and review date for every input.
Use in diligence
Five questions to ask next
- Which failures are technically detectable before the last intervention window?
- Who accepts or rejects an alert, and on what evidence?
- How does an accepted recommendation enter the work-management process?
- How will the plant verify that the intervention addressed the predicted condition?
- What must be true for the program to scale beyond the pilot site?
