Business Process Architectural Requirements - Vertical Slice

This type of diagram shows the key architectural elements required to realize a given Business Process. Each layer exposes capabilities to the layer above. For example, the Business Architecture layer with its Business Process and Activities provide Business Capabilities to the External Roles and Actors. Business Apps provide Application Capabilities to the Business Processes and Activities. IT Software provides IT Capabilities to the Business Apps and Enterprise DB Schemas. These capabilities are captured on the <<EA2 Provides..>> connectors, which can be confirmed against the Required Capabilties that each element can have.

There are three levels of life-cycle information represented on this diagram.

  1. Each element has life-cycle information indicating when it was or will be deployed and when it was or will be retired.
  2. The "Provides" connectors have life-cycle information indicating when an element did or will begin providing a capability to the associated element and when it stopped or will stop providing it.
  3. The Roadmap Phase indicates that the architectural configuration should be in place during its life-time.

You can track the progress of your architectural changes against the Roadmap by comparing the different life-cycles. See the sample Roadmap Phase Configuration Item Life-cycle Verification Report

.Diagrams of this sort can get rather large and messy. To remedy this, you can create multiple diagrams showing different areas of the architecture being applied to the Business Process. As long as the Business Process appears on each diagram, the reporting mechanism will report on them as if they were one diagram. Furthermore, if the same Roadmap Phase is on each diagram, they will also be considered one Roadmap Phase diagram for reporting purposes.
