Service chain optimization
Service chain optimization is the application of processes and tools that embrace all functions for improving the efficiency, productivity and, eventually, the profitability of service organizations. In this regard, profitability of a service organization is measured by the revenue generated from service demand (in the form of service work orders being carried out), and by the costs due to activity of the enterprise's human resources (who provide the service).
