AAATA focused on five KPIs that measured maintenance performance against service reliability and efficiency. These KPIs are set on a dashboard and provide alerts for the fleet manager to find out what is actually happening.
To help increase pullout availability, Percentage of Work Orders (WO) Opened by time and location or shop, measured the amount of time work orders remained in open status. By looking into factors that contribute to vehicle downtime, maintenance teams can explore more ways to improve efficiency and increase cost-effectiveness of repairs. Perhaps maintainers are waiting for parts, or the WO simply needed to be closed? Looking at this metric enables maintenance to dig deeper into the problem and look for possible solutions.
Percentage of Work Orders Opened by Class tracks scheduled work against unscheduled work, as well as road calls, and can be a lagging indicator of preventative maintenance performance. An increased percentage of unscheduled work (i.e., reactive maintenance) means breakdowns occurred more frequently, and underlying issues should be investigated. Conversely, proactive repairs reduced costs, mitigated downtime and negative impacts on operations. AAATA’s goal was to increase scheduled work versus unscheduled work and almost eliminate road calls. That would indicate that AAATA has a good preventative maintenance program which increases the safety and reliability of the fleet.
Direct vs Indirect labor is an efficiency metric that measures the amount of time employees are jobbed on working on an asset against time spent performing work activities not related to assets (e.g., attending shop meetings, cleaning the shop, or assisting inventory with counting). Agencies normally maintain a ratio of 80% direct labor to 20 % indirect labor for optimal technology utilization and staffing. Imbalances could indicate problems with workload and staffing levels. For example, a high percentage of indirect labor by service technicians might suggest overstaffing as most mechanics are typically focused on working directly on an asset.
Backlog by equipment type shows how much how much work is there waiting to be done and helps to identify staffing needs. Unaddressed backlogs – deferred work piling up – could lead to breakdowns that compromise safety and service reliability. Tracking the amount of work needed on asset groups also can help identify which assets are close to being retired or needed to be rehabilitated. Tracking this KPI helped AAATA identify additional staffing in the body shop to get ahead of the backlog and keep vehicles in good, working order.
Tracking PM Compliance not only facilitates the reporting required to regulatory bodies but identifies workload and forecast projected work. For AAATA, it provides acceptable timeframes for work and what should be done to accomplish the work needed, including scheduled repairs and addressing every single discrepancy found to preempt vehicle failures.
Finally, AAATA tracked Standard Repair Time, which is the number of labor hours to do a specific task; used to manage schedules; real-time labor capture; identify potential areas of improvement – skills training, gap in workforce, shop tooling needs. Improve production efficiency by providing an accurate estimate of time needed for scheduled work.
