An increase of process awareness within organizations and advances in IT systems led to a development of process-aware information systems (PAIS) in many organizations. UPROM is developed as a unified BPM methodology to conduct business process and user requirements analysis for PAIS in an integrated way. However, due to the purpose, granularity and form of UPROM artifacts, one cannot analyze the software requirements in detail with (semi-)formal methods for properties such as completeness, compliance and quality. In contrast, Problem Frames modeled using the UML4PF tool can be used for such analysis. But using the Problem Frames notation and corresponding methods alone does not cover a direct support for building a PAIS. Hence, in this work we propose to integrate UPROM and UML4PF using model transformation. We use eCompany, a project which is part of an e-government program, as running example.
