Evaluating an (implemented) Business Rules Management Solution (BRMS) is not a frequently conducted process within organizations. A tool is needed, which supports this process and supports future BRMS implementations. A literature study is conducted on the relevant building blocks of a BRMS. The results are validated through qualitative expert interviews. This resulted in the BRMS analysis tool that can be utilized to structure the analysis for one or multiple BRMS implementations. Next, the BRMS analysis tool is applied at 13 organizations that implemented a BRMS. The BRMS analysis tool provides the BRMS implementation stakeholders with a tool that structures, in a systematic and controlled way, that is capable to analyze a BRMS implementation for one or multiple organizations. This research contributes to structured and managed information which is important for better business and IT alignment. Furthermore, structured and managed information contributes towards the easier creation of a business case.
