I wrote this well over a decade ago while working in a few mining organizations in Australia. It has stood up pretty well over time so I thought I would post it here.
As a result of recent audits and reviews of various medium to large-scale industry. I have found the following to be a general observation regarding systems of work.
As technology for maintenance has moved forward there has been an increasing demand on the time of the maintenance-planning department.
Areas such as:
- Equipment profiling (Plant Index information)
- Parts listings (APL’s)
- Equipment strategy philosophies, investigation of proactive methods
- Analysis of system data
- Spares criticality assessments, ANSI management
- Advanced shutdown systems
- Equipment overhaul / replacement / repair procedures
- Backlog Management
- Weekly Scheduling
- Execution systems
- Introduction of work order vetting or a work requesting system can more accurately focus backlog lists to corporate rules.
- Agreed priorities and work order classifications.
- 24 hourly review systems and reports provide the trigger for future backlog control with valuable information also being available for daily review. Requires attention to work order-raising rules.
- Weekly capacity scheduling for maintenance purposes to be introduced. This will drive the worker availability to higher levels. Initial results generally are a surprise.
- Introduction of weekly KPI style reports highlighting areas of low compliance.
- Stores interfaces on holding, reserving, ordering and repairing equipment.
- Review reports for RCA and further analysis.
- Backlog
- Planned Work Orders (Minimum 1 Crew week)
- Unresourced
- Unestimated
- Waiting for parts
- Age of work orders by priority
- Backlog forward resources (Crew weeks equivalent 4 – 5 weeks)
- Average work order life
- Scheduling
- Planned / Scheduled Ratios (Inclusive of standing work orders)
- Maintenance type ratios
- Overtime as a percentage of total man hrs
- Contractor hrs
- Report of Unplanned / Unscheduled work orders per week
- Work order criteria
- Planning criteria
- Work package development
- Execution methods
- Inclusion of repairs
- Worker flexibility
- Areas of investigation
- Either RCA / or other optimization technique
- Crew sizes
