Global software development (GSD) is originally an outsourcing technique the development take place globally the offshore and on-site software teams participates their development effort with different time zone and language and culture. The main aim of this paper is to study the impact of offshore and onsite teams knowledge sharing and trust behavior in the overall outcome of GSD project. The objective of this paper is to measure the various factors that contribute to the knowledge sharing and trust among offshore/on-site development teams towards the outcome of GSD. In this paper, we are trying to evaluate the impact of offshore/on-site teams knowledge sharing and trust behavior on the overall process of GSD via ontology retrieval system by creating knowledge sharing and trust ontology. We have been formulated set of hypothesis to test the behavior of knowledge sharing and trust among offshore and onsite teams in GSD based on the data from literature studies [15,16,17,18]. In the result, we found out offshore/on-site teams trust, and knowledge sharing is positive impact in overall process of GSD.
