Hi everyone 👋,

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.

🔍 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)

✅ 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

🛠 Scope

• Open pit surface mining fleets & infrastructure (e.g., haul trucks, shovels, drills, dozers, support equipment)
• Day-to-day and shutdown execution perspectives welcome

💡 What would be most helpful

• Your Top 5–10 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 👍
