This section describes the application of the system implemented in this research using a case study of IT system of the retail chain stores with three subsystems, that is, 1) Point of Sale (POS) system, 2) Inventory system, and 3) Financial Accounting system. Each subsystem is responsible by each separate development team. The Inventory system contains the warehouse, procurement and delivery modules. The retail chain stores software product is used by two customers. Therefore, the configuration management system with integrated teaming is required to be able to release the patches or new development versions to individual customer.
