Comparison of models and standards for implementing IT service capacity management

Abstract

Due to the recent and significant growth of the information technology (IT) services, industries need some sort of framework and / or standards for the management of their services, especially IT services. So, it becomes necessary and essential to define and adopt a set of best practices for providing and effectively managing the technology and services offered throughout its life cycle. Currently, the management of IT applications and services becomes more complex. Predicting and controlling the problems associated with system performance and capacity planning has become a difficult task. For large IT projects, the costs related to performance tuning, performance management and capacity planning, generally turn out to be the biggest and the most uncontrollable costs. In recent years, a number of frameworks aimed at covering certain issues of IT service management have been developed. One of these issues is the IT service capability management. In this paper, a comparison between the models and standards used today regarding capacity management are presented. A comparison of the strengths and weaknesses of each of the models/standards on the capacity management is presented, so that it can guide organizations to select the model/standard that best suits their needs.
