The lead time for overhaul of Heavy vehicles is to be minimized. To meet this requirement, all the subsystems which are undergoing overhaul are to be closely monitored for the servicing, testing and delivery to the final assembly line. In addition, some of the assemblies can be carried out in parallel to minimize the lead time. This has resulted in improving lead time from 60 days to 45 days i. e. lead time reduction is 25%.
