A Faceted Taxonomy of Requirements Changes in Agile Contexts
Kashumi Madampe, Rashina Hoda, John Grundy · IEEE Transactions on Software Engineering · 2021
Background:Originally, developers aimed to identify most software requirements upfront in software development projects. However, agile methods explicitly encourage software requirements to be changed throughout development, i.e., many Requirements Changes (RCs) occur.Objective:The objective of this study is to better understand RCs and produce a taxonomy of RCs in agile contexts.Method:We ran a mixed-methods approach comprising a series of studies: an interview-based study (10 participants from New Zealand and Australia), a focused literature review, and an in-depth survey (40 participants world-wide).Results:Key characteristics of RCs in agile we found relate to differenttypesandforms, agile RCs have multiplereasonsandsources, they are brought by differentcarriers, and their emergence in agile is via a variety ofevents.Summary:The presented taxonomy provides a guide for software practitioners to use to help manage RC-related issues in agile contexts.
