OMMD™
Operational & Maintenance Maturity Diagnostic
A structured approach to understanding your current state across six critical areas of engineering and operational performance.
Delivered as a full diagnostic or targeted modules, OMMD™ provides a structured, site-based assessment across six core areas of operational and maintenance performance.
Each area is assessed against defined criteria, with objective scoring to give a clear view of current state and where performance is being lost.
This is followed by a report and debrief — highlighting priorities, assessing impact vs effort, and creating a practical roadmap that can be delivered in-house or supported by FourSix.
