TESTING COLLABORATIVE SOFTWARE ACQUISITION MODEL (COSA) FOR COTS PACKAGE ACQUISITION

摘要

The existing models meant to help in the ICT investments process are too heavy and technical to be used in SMEs. This paper reports the results of a case study in which the users carry out an ICT investment by applying the Collaborative Software Acquisition (COSA) model. The COSA model applies user participation and team-working in the acquisition of Commercial Off-The-Shelf (COTS) software products. The results show that the users are willing to commit to the COSA process. However, problems exist related to analysing system requirements and figuring out the system as a whole. The users should also investigate the existing COTS market before the requirement analysis and do the system requirements elicitation together with the evaluation of the existing COTS products.
