Abstract
This article approaches Engineering Requirements concepts and proposes the use of cognitive maps as support to the problem identification of the stakeholders during the requirements elicitation process. It presents a case study of the aerospace cluster of Sao Jose dos Campos, State of Sao Paulo. The cognitive map technique was developed to represent the views of the individuals, generating cognitive maps, which, in an aggregated way, express graphically the collective vision to support the decision-making process. Applied to Engineering Requirements, it has revealed the potential to promote the convergence of different points of view on the actual stakeholders’ needs in innovative fashion. This technique has demonstrated effectiveness when approaching the stated requirements early in the development process implemented throughout the life cycle of the system/product.
Highlights
IntroductionEngineering Requirements (ER) emphasizes the use of systems and techniques that ensure the completeness, consistency, and relevance of the system requirements (Sommerville 2006)
Engineering Requirements (ER) emphasizes the use of systems and techniques that ensure the completeness, consistency, and relevance of the system requirements (Sommerville 2006). It is a comprehensive area for product development, especially software, which has proven a sensible growth resulting from the valuation requirement, and it is an essential element of the development process (Martins 2001)
The present study resulted in four individual cognitive maps and a congregated map that allowed identifying the difficulties in requirements elicitation process for building complex systems, in this case, directed to the development of aerospace products in São José dos Campos
Summary
Engineering Requirements (ER) emphasizes the use of systems and techniques that ensure the completeness, consistency, and relevance of the system requirements (Sommerville 2006). It is a comprehensive area for product development, especially software, which has proven a sensible growth resulting from the valuation requirement, and it is an essential element of the development process (Martins 2001). The main phase of the product development cycle is the survey of stakeholder’s needs, in which the problems are identified involving them and the developers. Developers confirm that the specified requirements correspond to the stakeholders’ demands and their real needs. The requirements will be reviewed, and the problems, identified and remedied
