Challenge
Management lacked clear visibility into OEE components and could not quickly identify causes behind performance drops.
Solution
Built a modern HMI with strong traceability, historical context, and visual OEE decomposition for rapid bottleneck analysis.
Outcome
Operations leaders moved from reactive firefighting to faster, data-backed decisions and measurable efficiency improvements.
The HMI redesign centered on readability and actionability. Instead of adding more metrics, the focus was on the few indicators that drive operational decisions.
The result was a clearer view of where performance losses occur and a shorter path from detection to intervention.
Key improvements
- Better visibility into OEE losses over time
- Clearer operational handoffs across teams
- Faster root-cause exploration using historical context
Further documentation planned
- Add the production setting, user roles, and screen hierarchy behind the interface.
- Add before-and-after examples of dense screens simplified into faster operator workflows.
- Add measurable outcomes around reaction speed, traceability, and operator confidence.
Early implementation notes
- The primary screen should answer what is wrong now before it explains everything that happened before.
- High information density only works when visual hierarchy is strict and repeatable.
- Historical context belongs one step away, ready for drill-down without overloading the first view.
