Communication as an essential factor for effort estimation in GSD

Global Software Development, also known as Distributed Software Development, is originally an outsourcing technique in which the development teams hailing from diverse cultural backgrounds and located at distant remote locations participate in the software development efforts and provide their services through a tightly coupled computer networks like Internet. Accurate software cost and effort estimate are critical to both developers and customers. Communication difficulties of the Global Software Development projects adversely influence project cost which affects the cost and effort estimation of the software development. This paper is a survey on the effort estimation methods and the communication problems in the GSD projects. As a result suggests that the communication factor also consider for the effort estimation in the Global Software Development project, which results in the effective estimation.
