The trend towards Information Systems (IS) Outsourcing has become an important trend in recent years. With the prevalence of the Internet, international-based, as well as integration of, up-downstream outsourced IS is no longer independently contracted by single contractor units. This has seen relationships between contractor and customer - and between large contractors and small contractors - become increasingly complicated. This is further complicated by the dual pressures on the contractor of offering both a better customer service and controlling cost and quality issues while re-outsourcing to other end contractors. Conflicts can often occur between the members of any outsourcing project because acknowledgement diversities will result in different points of view. The purpose of this research is to identify the possible acknowledgement diversities that may occur between the three types of outsource (Customer, Contractor, End Contractor) during the four key stages of outsourcing (public bidding, contract signing, project development, checking before acceptance). The research basic of the dissertation will be structured by technology frame theories and interviewing will occur in several cases in order to obtain pointed theoretical and practical values for other researchers' reference.
