Methods and systems for modeling functional processes in enterprises, and for simulating and valuing the effects of various products and services on those processes, are described herein. A method in accordance with one aspect of the invention for marketing at least one of products and services to an operator of an enterprise includes presenting a first process model and a second process model. The first process model can graphically illustrate how at least one functional group in the enterprise responds to a selected operational circumstance.
