Phase C: Target Architecture

Objective    Approach     Inputs     Steps    Outputs

Objective

The objective of this phase is to identify a target architecture that will form the basis of the following implementation work.

Approach

Detailed guidelines for this phase are given under  Target Architecture Development.

Inputs

Inputs to this phase are:

• Request for Architecture Work
• Statement of Architecture Work
• Business Architecture - Version 2
• Re-usable architecture building blocks (from organization's Architecture Continuum, if available)
• Re-usable solutions building blocks (from organization's  Solutions Continuum, if available)

Steps

Key steps in this phase include:

1. Representing the baseline using the TOGAF Foundation Architecture to give a common starting point
2. Considering a number of architectural viewpoints to ensure that all stakeholder concerns in the required system are considered
3. Selecting a high-level model for the architecture
4. Establishing a set of criteria for service selection
5. Selecting the services required
6. Validating that business goals are met
7. Defining the architecture in detail; and
8. Conducting a gap analysis to identify any missing functionality.

The individual steps are explained in detail under  Target Architecture Development.

Outputs

The outputs of this phase are:

• Technical Architecture - Version 1
