PABRE: Pattern-based Requirements Elicitation

Abstract

This paper presents our PABRE method for facilitating requirements elicitation on the basis of requirement patterns with the goal of saving time and reducing errors during this activity. The process presented applies for elicitation in off-the-shelf selection projects driven by call for tenders processes and uses a requirement patterns catalogue. The process selects patterns from the catalogue that apply to the particular selection project, and convert them into the real requirements that finally configure the project requirements book. We show some benefits of the pattern approach for requirements engineers and IT consultants, as well as for customers. Finally we discuss the strengths and weaknesses of the proposal and identify some future work.
