There's a lot of Microsoft diagrams and workflows but this is by far my favorite:

It's a bit dated (2021 feels like a lifetime ago) but the information is still absolutely relevant. This diagram illustrates how different Microsoft reference architectures, models, and resources apply to the various levels of leadership and implementation. Great stuff!!

In particular, I like how the diagram illustrates the difference between the Cloud Adoption Framework (CAF) methodology and "Microsoft Cybersecurity Reference Architectures"(MCRA). In short, MCRA is more practical and is targeting the technical aspects. CAF on the other hand, is more conceptual and strategic.

For those interested, this diagram is part of a full set available at aka.ms/mcra
