Using ISO/IEC 29110, very small entities (VSEs) can perform a step-wise increment of their software process by switching between the different ISO/ IEC profiles. However, ISO/IEC 29110 provides no guidance on how to switch between profiles incrementally, other than resorting to costly software development process experts unaffordable for VSEs. To address this shortcoming, this paper shows how to model the variability of currently available ISO/IEC 29110 profiles in an integrated and configurable workflow with illustration on the Requirements Engineering (RE) activity. This workflow is linked to a questionnaire used to support automated process configuration. Thereby, the user can easily derive the ISO/IEC-compliant processes to switch between profiles incrementally. The feasibility of this approach is shown using open-source workflow management tools Synergia and YAWL.
