How to Score OEE Software Vendors: 10 Evaluation Criteria with Weighting Guide

Generic OEE evaluation criteria like "ease of use" and "customer support" produce generic outcomes — every vendor scores well on these in demos. The criteria that reveal real differentiation:

1. Machine connectivity quality — assessed by turning off WiFi during the demo and testing what still works
2. PM compliance in practice — verified by calling reference customers and asking their actual PM compliance rate before and after implementation
3. Real-time latency — confirmed by watching OEE update with a stopwatch in the demo
4. Integration depth — confirmed by requesting API documentation and having your IT team assess completeness
5. Implementation timeline — validated against three reference customers of comparable size
6. Data quality tools — assessed by asking how the system handles duplicate assets and inconsistent naming
7. Training approach — live vs recorded, availability in your timezone
8. Support response time — guaranteed in the SLA and tested by calling the support line during the demo
9. Price escalation cap — confirmed in the contract, not just quoted verbally
10. Data portability — confirmed by requesting a sample data export during evaluation

Create a weighted decision matrix with these columns: Criterion | Weight | Vendor A Score (1-5) | Vendor B Score (1-5) | Weighted Score.

Suggested Weights for Manufacturing OEE Selection

• Machine connectivity (your PLC brands): 20%
• Real-time OEE accuracy: 15%
• CMMS/maintenance integration: 15%
• Implementation quality (references): 12%
• Mobile and operator UX: 10%
• Multi-site reporting: 8%
• Support quality: 8%
• Pricing transparency: 7%
• Data portability: 3%
• Vendor stability: 2%

Complete the matrix independently per evaluation committee member before group discussion — independent scoring followed by calibration discussion produces better outcomes than group scoring, which tends toward consensus around the loudest voice.

Ask these questions in every OEE software demo:

• Turn off the demo WiFi — what still works? This reveals the offline capability vendors describe but rarely demonstrate.
• Show me OEE for 6 machines side by side for the last 30 days — multi-machine comparison is frequently limited to single-machine views in weaker platforms.
• Create a CMMS work order from a current OEE downtime event right now — how many clicks, and what maintenance context does the work order include?
• Show me what happens when the machine controller sends an error code we haven't categorized — how does the system handle unknown signals?
• Show me a reference customer in our industry who went live in the last 18 months — recency matters because products change significantly.

These five questions take 20 minutes in the demo and surface more useful differentiation than two hours of vendor-led feature walkthroughs.
