First-Time Fix is one of the most frequently measured key performance indicators (KPI) used by Field Service Organizations (FSOs). It is a very powerful metric to track. This KPI measures the percentage of times field service engineers (FSEs) are dispatched to a customer site and have the skills and parts with them to resolve the issue on the first visit. It is a powerful metric because it provides an indication of the FSO’s financial and operational health. In this sense, it is like the DNA of field service.
