Choosing among Custom Development, BPM and SaaS
In this paper, we develop a framework based on two well-known models; one widely used in project management and the other for defining software quality. The framework combines the project management triangle of Time – Scope – Cost (with Quality in the middle) with the FURPS model for software quality. FURPS is an acronym for Functionality, Usability, Reliability, Performance and Supportability. At the end of this paper, a calculation tool is provided to support an objective decision for your development approach. The calculation sheet lists these seven criteria and illustrates a set of relative scores per criterion for each approach.
