This chapter provides an overview of the contents of Part III.

Guidelines for Adapting the ADM Process

The Architecture Development Method (ADM) process can be adapted to deal with a number of different usage scenarios, including different process styles (e.g., the use of iteration) and also specific specialist architectures (such as security). Guidelines included within this part of TOGAF are as follows:

• Applying Iteration to the ADM discusses the concept of iteration and shows potential strategies for applying iterative concepts to the ADM.
• Applying the ADM at Different Enterprise Levels discusses the different types of architecture engagement that may occur at different levels of the enterprise. This section then also discusses how the ADM process can be focused to support different types of engagement.
• Security Architecture and the ADM provides an overview of specific security considerations that should be considered during different phases of the ADM.
• Using TOGAF to Define & Govern SOAs shows how SOA concepts can be supported by the TOGAF framework and the specific SOA considerations for different phases of the ADM.

Techniques for Architecture Development

The following techniques are described within Part III: ADM Guidelines and Techniques to support specific tasks within the ADM:

• Architecture Principles - principles for the use and deployment of IT resources across the enterprise - describes how to develop the set of general rules and guidelines for the architecture being developed.
• Stakeholder Management describes Stakeholder Management, an important discipline that successful architecture practitioners can use to win support for their projects.
• Architecture Patterns provides guidance on using architectural patterns.
• Business Scenarios describes the Business Scenarios technique, a method for deriving business requirements for architecture and the implied technical requirements.
• Gap Analysis describes the technique known as gap analysis. It is widely used in the TOGAF ADM to validate an architecture that is being developed.
• Migration Planning Techniques describes a number of techniques to support migration planning in Phases E and F.
• Interoperability Requirements describes a technique for determining interoperability requirements.
• Business Transformation Readiness Assessment describes a technique for identifying business transformation issues.
• Risk Management describes a technique for managing risk during an architecture/business transformation project.
• Capability-Based Planning describes the technique of capability-based planning.
