In this book I considered communication and coordination in Offshore Software Development Outsourcing (OSDO) from vendors' perspective, in order to identify what are the challenges that hamper the success of communication and coordination in OSDO, as well as to find out what are the mitigation strategies that can be practiced to overcome these challenges. The main objective of this project is to develop Communication and Coordination Challenges Mitigation Model (CCCMM) for OSDO vendors. The model will assist OSDO vendors in identifying, analyzing and mitigating the communication and coordination challenges by providing solutions. CCCMM, will assist OSDO vendors in gauging their level in order to efficiently manage communication and coordination activities in OSDO relationship with their clients. The model will assist vendors in improving their current level by suggesting various practices. The model will contribute to the body of knowledge in the field of Global Software Engineering. The model will assist industry practitioners in managing communication and coordination activities in OSDO relationship.
