A risk model to allocate resources to different computerised systems

Abstract

The majority of large organisations operate and maintain significant portfolios of computerised systems. All Information Systems (IS) managers are increasingly faced with the task of doing more with less. To cope with this ever increasing demands on the one hand and limited resources on the other, acceptable tools and techniques are required to manage available resources optimally and to apply them where they are needed most. This paper presents an overview of a case study which entails the development, and practical application, of a model to allocate resources to different computerised systems based on risk, success and importance of each system. By applying statistical techniques (linear regression and optimisation) to empirical data, important risk and success factors were identified, systems were prioritised and a model to allocate resources was formulated.
