This document introduces the Value Delivery Modeling Language (VDML), a new modeling language to support value-driven business design. VDML focuses on representing businesses as value networks by modeling the flow of deliverables and contributions of value. It provides a higher level of abstraction to model what a business does, how it operates, and who is responsible. VDML is intended to help businesses address challenges like finding the most profitable business models and efficient partnership arrangements through computerized modeling and analysis. The document outlines several key VDML concepts like capabilities, collaborations, and value propositions and shows some early examples of how VDML can be used to model business networks and value flows.
