A business capability defines "what" a business does at its core. This differs from "how" things are done or where they are done. Business capabilities are the core of business architecture. As shown in the below business mapping diagram, business capabilities provide an abstraction of the business reality in a way that helps to simplify conversations between interested stakeholders. Defining business capabilities supporting components (roles, processes, information, and tools) provides a business context for those supporting components. Creating a business capability model for the enterprise promotes a common understanding of the business, and a Business Analyst can choose tools like EdrawMax or EdrawMax Online to create factually correct business capability resource map diagrams.
