The unit makes explicit the context that shapes the selection of measures and the interpretation of information products, with the assumptions it embodies and the constraints it imposes: organisational processes (possibly as a descriptive process model), application domains, technology, interfaces between divisions or departments, and structure. This characterisation is taken into account in every later activity and task.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
