Using non-functional requirements templates for elicitation: A case study

Abstract

It is still an open question how to achieve a proper balance between the cost and value of requirements elicitation. When deciding to assign time and other resources to elicitation, one needs to know what its effectives would be. In the paper we investigate the Structured Elicitation of Non-functional Require-ments(SENoR) method. The method is composed of a sequence of short brainstorming sessions driven by ISO25010 quality characteristics. It uses Non-functional Requirements Templates (NoRTs) to support the elicitation process. Our exploratory case study on cost and effectiveness of SENoR and NoRTs included 7 projects that developed tailor-made web applications. The findings show that two 1.5-hour elicitation workshops can result in non-functional requirements of stability at the level of 80%.
