Abstract

In the present day products are progressively more developed globally in alliance between subcontractors, third-party suppliers and in-house developers. GSD is an outsourcing method in which the development team hail from dissimilar cultural, background and situated at remote locations contribute in the software development efforts and offer their services through electronic media like Internet. Communication difficulty of the GSD projects badly persuades project cost which affects the cost and effort estimation of the software development. So it is required to consider communication and coordination factors also for the effort estimation in the GSD project which results in the valuable estimation. There are many studies performed by many people for effort estimation methods for Co-located projects. However, there are evidences that the co-located approaches are not readily applicable to Global Software Development. So, this paper focus on deriving the suitable metrics to overcome the impact of communication and coordination factors while computing effort for distributed Software Development. The successful effort estimation of GSD projects must also consider the communication as a chief factor as it adversely affects the success of the projects and deriving the core metrics to reduce the impact of these challenges.
