Each business function embodies units of both a core process and a subsystem. The core process provides a subprocess that defines the sequence of work steps to be followed. The subsystem applies the resources and targets to accomplish that work.

Horizontal arrows (left-to-right) indicate the general lifecycle sequence of subsystem object states. The subsystem sustains the company's business functionality for each lifecycle state, by applying resources and controlling the way work is performed.

Vertical arrows (top-to-bottom) indicate the general workflow sequence as the core process traverses the subsystem layers. Upward dashed arrows indicate delivery of results to customer. The core process initiates action by the business functions.

A subprocess of the core process coincides with each subsystem intersection. In this way, the product and resource frameworks tightly integrate the core process and system structures.
