Execution model for outsourced corrective maintenance

We focus on corrective maintenance carried out in the outsourced mode under strict service level agreements and present the characteristics of the problem and the activities performed. We detail the information requirements for various maintenance services, such as, emergency maintenance, production support, and corrective maintenance. We present the concept of a system execution model with its constituent nodes and arcs and present the steps to build the same. We present a case study of a large commercial outsourcing project to demonstrate how the execution model can help in making quick decisions that reduces the turn around times of corrective maintenance requests.
