@AB First I want to clarify some terminology, for us IDP != Dev Portal. Dev Portal is a small part of our IDP 🙂 . And yes, we do have a cost benefit analysis for Dev Portal, but I can't share the exact numbers. As mentioned in the Value Stream Mapping section, we quantified the impact based on time/productivity, which can be translated into $. You can also project this out into the future, since the problem is only becoming bigger as the organisation grows. The result was very clear in our case. Obviously we had to make some good assumption around effort for building and maintaining Dev Portal.
