Supporting the teaching of design thinking techniques for requirements elicitation through a recommendation tool

摘要

The development of systems with different features becomes increasingly challenging, given the actual context, implying on the search for new approaches for requirements elicitation. One of these approaches is design thinking (DT), a process of encouraging innovation used by designers, which presents itself as fundamental in the success of new products. This scenario motivates the importance of knowing DT concepts and their techniques, which can support requirements elicitation. In this context, the authors present DTA4RE (DT assistant for requirements elicitation), a tool that suggests DT techniques for requirements elicitation, which can be used by both students and professionals who would like to adopt DT in their projects. The DTA4RE is composed of a set of 27 techniques that could be suggested to the user through a recommendation questionnaire as well as an open repository with material to support the application of these techniques. Results from the authors' two empirical studies with software engineering undergraduate and graduate students and industry professionals indicate that DTA4RE has helped in the selection of and in the learning of DT techniques when considering real problems. Most participants considered the questions from the recommendation questionnaire easy to answer, and the techniques suggested by the tool useful.
