Abstract
The evolution of outsourcing Information Technology (IT) Services has been accompanying the movement of technological innovations and the changes in IT governance. This development has motivated organizations to conduct decision-making integrating preferences from managers of different sectors in the Enterprise in order to improve the decision process. This paper presents a group decision model that can incorporate the preferences from different managers based on Promethee method and analysis of individual priorities with the aim of choosing an appropriate alternative for outsourcing IT service. The model is illustrated by a case study in an Enterprise in the Commercial Sector using the preferences from three managers (Support and IT Services Manager; Infrastructure Manager; and Development Systems Manager) demonstrating the benefits to formalize the integration among them to facilitate achieving an adequate alternative for outsourcing IT service.
