Due to sprawl and poor portfolio management, organizations often have too many applications. To address this problem, companies need to align the rationalization criteria of their application portfolios in a way that can be understood by those who manage them.
There is no "one size fits all" regarding rationalization. The best way to achieve your success is by playing to your strengths and building the framework that aligns with your goals and limitations. Remember that by applying a rigid approach with inflexible inputs, you can delay or prevent yourself from realizing value.
