Field service technicians play a pivotal role in ensuring smooth operations for businesses that rely on on-site equipment maintenance and repair. In today’s fast-paced business environment, monitoring and optimizing the performance of field service technicians is crucial. Key Performance Indicators (KPIs) serve as valuable metrics to assess and enhance the efficiency of field service operations. In this blog post, we will delve into the main KPIs that businesses need to consider for their field service technicians.

First-Time Fix Rate (FTFR):

  • The First-Time Fix Rate measures the percentage of service calls resolved on the first visit. A high FTFR indicates efficient problem diagnosis and resolution, reducing downtime for clients and cutting operational costs for the service provider. Tracking FTFR helps identify areas for improvement, such as technician training or access to necessary equipment and spare parts. New technologies such as remote visual assistance can assist with FTFR.

Response Time:

  • The time it takes for a field service technician to respond to a service call is a critical KPI. Swift response times enhance customer satisfaction and demonstrate a commitment to timely issue resolution. Analyzing response times allows businesses to optimize technician schedules, allocate resources effectively, and meet or exceed service level agreements (SLAs).

Average Repair Time:

  • A key indicator of efficiency, Average Repair Time measures the time it takes to complete a repair once a technician is on-site. Minimizing this duration not only satisfies customers but also allows service providers to handle more service requests and increase overall productivity. Regularly evaluating and optimizing repair processes can contribute to a reduction in average repair time.

Utilization Rate:

  • The Utilization Rate indicates the percentage of time a field service technician spends on billable activities compared to their total available working time. Maximizing utilization rates ensures that businesses are getting the most value from their workforce. Factors such as effective scheduling, efficient dispatching, and streamlined administrative processes contribute to improved utilization rates.

Customer Satisfaction (CSAT) and Net Promoter Score (NPS):

  • While not directly operational, customer satisfaction metrics are integral to the success of field service operations. CSAT and NPS provide insights into how well technicians meet customer expectations and whether they leave a positive impression. Regularly collecting and analyzing customer feedback helps identify areas for improvement and reinforces the importance of customer-centric service.

Inventory Management:

  • Efficient inventory management is crucial for field service operations, impacting both cost control and service delivery. KPIs related to inventory, such as stockout rate and inventory turnover, help businesses ensure that technicians have the necessary tools and spare parts to resolve issues promptly. An optimized inventory system minimizes delays, improves first-time fix rates, and reduces carrying costs.

Travel Time and Mileage:

  • Field service technicians spend a significant portion of their workday traveling between locations. Monitoring travel time and mileage provides insights into the efficiency of route planning and helps identify opportunities for optimization. Utilizing location-based services can enhance route planning, minimize travel time, and reduce fuel costs.

Scheduled vs. Unscheduled Maintenance Ratio:

  • This KPI assesses the balance between planned maintenance activities and unscheduled repairs. A high ratio of scheduled to unscheduled maintenance indicates effective preventive maintenance programs, reducing unexpected breakdowns and minimizing disruptions for clients. This not only improves equipment reliability but also contributes to better resource planning.

Work Order Completion Rate:

  • Work Order Completion Rate measures the percentage of assigned tasks that field service technicians successfully complete within a specified time frame. This KPI reflects the efficiency and reliability of the workforce. Regularly tracking completion rates helps identify trends, spot potential issues, and adjust workflows to optimize overall performance.


In the dynamic world of field service, tracking and analyzing key performance indicators are essential for ensuring optimal efficiency and customer satisfaction. By focusing on metrics such as First-Time Fix Rate, Response Time, Average Repair Time, Utilization Rate, Customer Satisfaction, Inventory Management, Travel Time and Mileage, Scheduled vs. Unscheduled Maintenance Ratio, and Work Order Completion Rate, businesses can fine-tune their field service operations and stay ahead in a competitive landscape. Embracing data-driven decision-making empowers organizations to continuously improve their processes, meet customer expectations, and unlock new levels of success in the field service industry.
