Objectives

Togaf adm business architecture.gif

  • Develop the Target Business Architecture that describes how the enterprise needs to operate to achieve the business goals, and respond to the strategic drivers set out in the Architecture Vision, in a way that addresses the Request for Architecture Work and stakeholder concerns
  • Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Business Architectures
  • Develop a Baseline Business Architecture
  • Develop a Target Business Architecture
  • Business Modelling
  • Architecture Repository population with leading industry business standards

Business Modelling

Using models like:

  • Activity Models (aka Business Process Models)
  • Use Case Models
  • Class Models
    • Presentation in UML is possible
  • Node Connectivity Diagrams
  • Information Exchange Matrix

Architecture Repository

To store:

  • Generic Business Models
    • OMG group models
  • Business Models
    • eg. REA
    • eg. STEP
    • eg. RosettaNet
  • Enterprise-specific building blocks
  • Applicable standards

Inputs

Inputs to Phase B: Business Architecture are:


Steps

Steps in Business Architecture are:

  1. Select reference models, viewpoints and tools
  2. Develop Baseline Business Architecture Description
  3. Develop Target Business Architecture Description
  4. Perform Gap Analysis
  5. Define roadmap components
  6. Resolve impacts across the Architecture Landscape
  7. Conduct formal stakeholder review
  8. Finalize the Business Architecture
  9. Create the TOGAF: Architecture Definition Document

Outputs

Architecture Deliverable outputs of Business Architecture may include the following:

  1. TOGAF: Statement of Architecture Work (updated)
  2. Validated business principles, business goals, and business drivers
  3. Elaborated Business Architecture principles
  4. Draft TOGAF: Architecture Definition Document
  5. Draft TOGAF: Architecture Requirements Specification
  6. Business Architecture components of an TOGAF: Architecture Roadmap

Architecture Artifacts outputs may include the following:

Security Adaptations for ADM

  • Determine the legitimate actors who will interact with the system (Business scenarios / use-cases)
  • Produce a baseline of current security-specific business processes
  • Determine whom/how much it is acceptable to inconvenience with security measures
  • etc...
  • Determine the cost of asset loss/impact in failure cases
  • Identify and document the ownership of assets
  • etc...
