TOGAF 9 Guidelinesand Techniques Ver1 0

  1. 1. Summarised - 2010
  2. 2.  Applying Iteration to the ADM  Applying the ADM at different Enterprise Levels  ADM Cycle Approaches
  3. 3. Architecture Context iterations allow initial mobilization of architecture activity by establishing the architecture approach, principles, scope, and vision. Architecture Definition iterations allow the creation of architecture content by cycling through Business, Information Systems, and Technology Architecture phases. These iterations also allow viability and feasibility tests to be carried out by looking at opportunities and migration planning. Architecture Governance iterations support governance of change activity progressing towards a defined Target Architecture. Transition Planning iterations support the creation of for mal change roadmaps for a defined architecture
  4. 4.  Two process styles can be adopted within the ADM for the definition of architectures: ◦ Baseline First: In this style, an assessment of the baseline (i.e., current state) landscape is used to identify problem areas and improvement opportunities. This process is suitable when a target solution is not clearly understood and agreed upon. ◦ Target First: In this style, the target solution is elaborated in detail and then mapped back to the baseline, in order to identify change activity. This process is suitable when a target state is agreed at a high level and where the enterprise wishes to avoid proliferating current business practice into the target model.
  5. 5. The enterprise must be partitioned into different areas, each of which can be supported by architectures (Subject Matter, Time Period and Level of Detail)
  6. 6. Key Benefits 1. It is lightweight, as multiple architectures can be developed against a single Request for Work, project plan, etc. 2. It allows for very close integration of architectures at different levels in the organization. 3. It works well when all architectures are being developed by a single team. Key Limitations 1. It does not explicitly set out governance and change management relationships between the different architectures. 2. It requires all architectures to be completed in sequence and potentially released at the same time. This may delay the release of strategic architectures or prevent specific Capability Architectures from being developed. 3. Similar architectural activities are repeated within a number of phases within the ADM. It may become difficult to distinguish the differences between different phases.
  7. 7. Key Benefits 1. It is comprehensive. All ADM activities are carried out at all levels. 2. It establishes explicit governance relationships between architectures. 3. It allows for federated development of architectures at different levels in the organization. Key Limitations 1. It requires the establishment of an enterprise-wide governance hierarchy to be effective. 2. It does not work well when many architectures are being developed by the same team of architects.
