Thanks Michael, really appreciate you taking the time to share these practical insights. Tracking days late, pastβdue work, and planned vs. actual time are great ways to keep execution honest and continuously improve scheduling accuracy and crew effectiveness. Your points add valuable, realβworld perspective to the discussion.

My biggest concern would be getting the maintenance done on time. I would keep track of average days late for getting maintenance done to gauge how well maintenance is getting done on time. I would also flag what maintenance is past due.
If you schedule how much time the maintenance should take and track how much time it actually takes, you could track planned time verses actual time for all maintenance tasks. Then you could see how much time it typically takes and can adjust scheduling to suit actual needs, talk to the maintenance crew if the actual time seems excessive, and/or pay close attention to the job the next time if the time seems excessive to see what is making it take longer than expected. If you post these metrics, you may encourage crews to get the work done in a timely manner.

Subject: Top 10 Maintenance Execution Efficiency Metrics (Open Pit β Surface Mining)
Hi everyone π,
I'm looking to tap into the group's collective experience to help identify a strong, practical set of Maintenance Execution Efficiency metrics, specifically for open pit surface mining operations.
π What I'm not looking for
To keep this focused, let's please exclude:
- Availability
- Reliability
- Utilization
- Production metrics
(these are well-covered elsewhere and not the intent here)
β
What I am looking for
Metrics that directly reflect how efficiently maintenance work is executed, such as:
- Planning & scheduling effectiveness
- Craft productivity / wrench time
- Schedule compliance & stability
- Work execution quality, flow, and discipline
- Material / tool readiness impacting execution
- Rework, delays, and execution waste
π Scope
- Open pit surface mining fleets & infrastructure (e.g., haul trucks, shovels, drills, dozers, support equipment)
- Day-to-day and shutdown execution perspectives welcome
π‘ What would be most helpful
- Your Top 5β10 execution efficiency metrics
- If possible, Brief context on:
- Why you use it
- What behavior it drives
- Any lessons learned (gaming risks, maturity level required, etc.)
I'm aiming to compare and converge on a short, high-impact execution efficiency scorecard that actually drives better maintenance outcomes in the mine, not just more reporting.
Appreciate any insights, examples, or hard-earned lessons. Looking forward to the discussion π
