Handling requirements dependencies in agile projects: A focus group with agile software development practitioners

Agile practices on requirements dependencies are a relatively unexplored topic in literature. Empirical studies on it are scarce. This research sets out to uncover concepts that practitioners in companies of various sizes across the globe and in various industries, use for dealing with requirements dependencies in their agile software projects. Concepts were revealed through online focus group research, using an adapted forum for discussion, and grounded theory to analyze the responses. Our study resulted in the following findings: (1) requirements dependencies occur in agile projects and are important to these projects' success just as this is known for `traditional' software projects'; (2) requirements dependencies (i) were considered and treated as part of risk management, (ii) were deemed a responsibility of the individual team members, and (iii) mostly did affect project planning; (3) continuous communication and collaboration - two essential features of any agile method, were found critical to mitigating the risks due to dependencies; (4) a hybrid approach to architecture between agile and plan-driven methods was perceived to yield maximum scalability and help coping with dependencies; (5) `cross-cutting concerns', a category of dependencies, were not uniformly understood in an agile context and require more research

Evaluating cross-organizational ERP requirements engineering practices: a focus group study

This focus group study presents our first validation of practices for engineering the coordination requirements in cross-organizational Enterprise Resource Planning (ERP) projects. The study evaluates 13 practices addressing a variety of coordination aspects crucial to ERP projects. These practices are results in previously published research publications by the first author. The practices are formulated in response to practitioners' needs at ERP adopting organizations. The proposed practices have now reached the stage where we need some independent feedback as to the extent to which they fit the realities of practitioners. We perform this validation by means of a qualitative research approach, namely the focus group method. Current software engineering literature provides few examples of using focus groups in the evaluation of good software development practices. Because of this, providing reflections on our focus-group-based validation experiences will be of value to both the research community and practitioners
