The Five Subject Resource Roles

Every subject resource contributing to an activity fills one of five Subject Resource Roles — the specific functional contribution it makes toward transforming an input into an output.

Space-Infrastructure resources provide the physical location, environment, and structures an activity needs to happen at all. Operator resources — usually people, equipment, or both — transform inputs into outputs by applying power and direction. Direction resources convey the command to perform an activity along with the instructions for how, when, and where to execute it. Financial Capacity resources fund the other resources involved. Power resources fuel or energize the operators so they can actually do the work.

The book’s own example makes the five roles concrete: a wheat farmer harvesting a field. The field itself fills the Space-Infrastructure role. The farmer and the tractor act as Operators. Direction comes from the farmer’s knowledge of how to harvest the crop. Power comes from gasoline. And Financial Capacity comes from the money used to buy the seeds, the tractor, and the land in the first place — every other role in the activity was enabled by that funding.

These roles are functional, not categorical — a resource’s role describes what it does in a given activity, distinct from which of the six resource categories it belongs to. That’s what lets the same underlying resource type show up in different roles across different activities, depending on what job it’s actually doing.
