Requirements Engineering plays a central role on software-based information system specification and evolution, and in the alignment between Business and IS/IT, nevertheless, contributes from other areas of research are important to advance and mature existing solutions. Our recent work in eliciting and managing requirements in ill-defined contexts, from a process-perspective, presents some challenges that need to be tackled from other perspectives. We present some insights from three different areas (business model, strategy and goals, and enterprise architecture) concerning innovative methods and techniques, to apply in our existing V-process solution. At the moment, we have defined the methods and techniques to include and adapt, and will empirically test and evaluate their suitability and results in new contexts.
