Four dimensions

What this topic is really about
The "Value streams and processes" dimension addresses how the various parts of the organization work in an integrated way to enable value creation through products and services — defining activities, workflows, controls, and procedures. The other dimensions cover staff/culture, technology/information, and external relationships respectively.
The four dimensions are Organizations and people, Information and technology, Partners and suppliers, and Value streams and processes. "Risks and incidents" sounds plausible but is not a dimension — risks are addressed in the Risk management practice and incidents in the Incident management practice.
