Another method to gauge work force activity, availability and productivity is analyzing much time spent driving, in a customer home, at lunch and so on. This can be done by looking at the time stamps in the billing system. Occasionally, this requires some process improvement in the tech/dispatch relationship.
Ensure that techs update instantly and a dispatcher inputs the correct time stamps. If a tech leaves a job at 9:15 a.m. and starts the next job at 9:30, it is logical to assume 15 minutes of drive time between those jobs. By looking at these numbers, an average drive time can be determined, per tech. It is fair to assume that the largest gap between jobs is lunch time.
