Prioritization of Applications for Software-as-a-Service Migration Using Total Life Cycle Costs and the Analytic Network Process
The current state of the world economy has made Software-as-a-Service (SaaS) an appealing concept for organizations with a small budget for IT infrastructure investment. In a SaaS setup, companies subscribe software applications on a pay-per-use system from external service providers over the internet. However, these companies are looking for a decision framework that can be used to prioritize business software applications for SaaS migration. This paper attempts to fill in this gap by proposing a hybrid methodology which is composed of a total System Life Cycle (SLC) cost analysis for cost estimation and the Analytic Network Process (ANP) for prioritization.
