Performance Measure Definition: Fleet Maintenance per Month

Description: This indicator tracks the percentage of vehicles that receive preventative maintenance when due each month.
Desired Outcome: Vehicles receive required maintenance on time.
Relevance: Fleet reliability is a key component of the department’s ability to provide timely care to the community. Preventative maintenance minimizes unit failures or unanticipated repairs, thereby ensuring dependable fleet operation, which leads in turn to consistent department response and transport capabilities.
Measure Domain: Support Services
Type of Measure: Process
