Abstract

CARRIZO MORENO, Dante. Comparison on effectiveness of the software requirements elicitation techniques: novice and expert vision. Ingeniare. Rev. chil. ing. [online]. 2012, vol.20, n.3, pp.386-397. ISSN 0718-3305.  http://dx.doi.org/10.4067/S0718-33052012000300013.

Requirements engineering can use a lot of techniques to gather the users' needs. However, currently there are few practical guidelines and criteria for selecting techniques in a software development project. This paper tries to know the vision that novice requirements engineers have about the effectiveness of requirements elicitation techniques and compare it with the requirements experts' vision. To carry out the comparison, repertory grid technique was used. This technique allows knowing indirectly the subject's opinion on the techniques. The results show a substantial difference between both visions with regard to the techniques and elicitation context. This implies that a more extensive training, and primarily practice, is necessary in order for novice engineers to recognize differences in techniques effectiveness and decide with greater certainty about the most appropriate techniques to use in requirements elicitation sessions.

Keywords : Requirements engineering; requirements elicitation; elicitation techniques; contextual attributes; repertory grid.
