Exam OGEA-101 Topic 9 Question 81 Discussion

The chart shown is a Gantt chart, which is commonly used for project management to illustrate a project schedule. In the context of TOGAF (The Open Group ArchitectureFramework), which is a framework for enterprise architecture, this Gantt chart is demonstrating the sequenced approach to the Architecture Development Method (ADM). The ADM is the core process of TOGAF which provides a tested and repeatable process for developing architectures. The ADM is described as being iterative, over the whole process, between phases, and within phases. For each iteration of the ADM, a fresh decision must be taken about each of the parameters (scope, granularity, time period, and architecture assets).
The ADM consists of a number of phases that have to be followed in sequence:
* Preliminary Phase: Framework and principles
* Phase A: Architecture Vision
* Phase B: Business Architecture
* Phase C: Information Systems Architectures, including Data and Application Architectures
* Phase D: Technology Architecture
* Phase E: Opportunities and Solutions
* Phase F: Migration Planning
* Phase G: Implementation Governance
* Phase H: Architecture Change Management
* Requirements Management
Each phase is dependent on the outputs of the previous phase and the Requirements Management phase runs throughout. The Gantt chart clearly shows the dependency and sequence in which these phases occur, implying that a structured approach is followed to produce the enterprise architecture.
