Customising software products in distributed software development A model for allocating customisation requirements across organisational boundaries

Requirements engineering plays a vital role in the software development process. While it is difficult to manage those requirements locally, it is even more difficult to communicate those requirements over organisational boundaries and to convey them to multiple distribution customers. This paper discusses the requirements of multiple distribution customers empirically in the context of customised software products. The main purpose is to understand the challenges of communicating and allocating customisation requirements across distributed organisational boundaries. We conducted an empirical survey with 19 practitioners, which confirmed that communicating customisation requirements in a DSD context is a significant challenge. We therefore propose a model for allocating customisation requirements between a local, customer-based agile team and a distributed development team that uses a traditional development approach. Our conjecture is that the model would reduce the challenge of communicating requirements across organisational boundaries, address customers´ requirements and provide a focus for future empirical studies.
