A study on techniques for measuring requirement suitability considering project objectives and constraints

Abstract

The suitability of requirements that are developed and changed is a key factor to make a success of project. The key elements of requirement suitability are the objectives and constraints which are decided by scope. To ensure that requirements have suitability, our study proposes the techniques for measuring requirement suitability considering objectives, constraints and requirements. To calculate requirement suitability points, which are quantities calculated by these techniques, we develop indicators and metrics based on relationship among objectives, constraints and requirements, and propose expressions to quantify our indicators using MCDM (Multi Criteria Decision Making) techniques. An interpretation and usage of our techniques are described by statistical analysis. © 2012 Springer-Verlag.
