A cognitive approach of collaborative requirements validation based on action theory

Abstract

The requirements must be validated at an early stage of the analysis. The majority of existing approaches for validating requirements are used in a heterogeneous process, using a variety of techniques, relatively independent without any methodological or cognitive approach. In this work we present a cognitive approach based on action theory for collaborative requirements validation, through a set of steps that must increase the involvement of the client in this stage and to bring the customer mental model to the analyst one. A valid needs database is created, needs that remain invalid must be negotiated. At the end of this collaborative process, decisions will be made concerning who must participate during needs validation meetings with respect to the mental effort metric. This metric will classify according to the mental difficulty of execution of the prototype, the 'articulatory' and 'semantic' problems, and measure commitment and stakeholders motivation.
