Business Processes describe what the business does to suppport the Business Capabilities it provides to its constituents. It is devoid of any technology references. However, elements from all of the architectural views are required to realize a Business Process. The collection of all these elements is called a Vertical Slice of the enterprise architecture.
(EA)<sup>2</sup> provides an XML import file that provides the entire package structure required to support a Business Process. The package structure can be replicated for different stages of architectural development, e.g. current state, future state, or staged states over time. each one of these states contains packages to hold the Business Process for that point in time as well as for the architectural elements needed to realizs the Business Process. There are two approaches to showing the architctural elements that do not need to exclusive of each other. One approach uses the capabilities to map from one architectural layer to another while the other uses use cases and use case realizations.
The following links will take you to a discussion on the Business Process itself as well as the two vertical slice approaches.
