Technology Architecture

Develop a Technology Architecture for your architecture project

Phase D: Technology Architecture

Phase D is the Phase in TOGAF® that develops the Technology Architecture for an architecture project. Technology architecture is a description of the structure and interaction of the platform services, and logical and physical technology components.

Phase D develops the Target Technology Architecture that enables the data and application components (developed in Phase C), which in turn enable the business components.

 

 
 

Approach: Phase D

The architectures developed in Phases B, C and D combine to enable the Architecture Vision – which addresses stakeholder concerns and the Request for Architecture Work.

As with the other architecture development phases, Phase D identifies candidate Architecture Roadmap components to make the transition from Baseline to Target.

The steps in Phase D are almost identical to the steps in Phases B and C – the main difference is that the focus is now on Technology. So this includes Technology Reference Models and Technology criteria or measurements – such as Performance, Maintainability, Location and Latency, or Availability.

It’s very important to identify outputs and deliverables to help build a Technology Architecture that truly enables the Information Systems and Business Architectures.

Getting the right scope accelerates pay-back, while an excessively large scope will frustrate a successful implementation. This is not about deploying technology for its own sake, but developing a Technology Architecture that really does address the Architecture Vision and Request for Work.

This phase provides a clear statement of the Architecture Work that will be delivered in an iteration of the ADM, delivering a high-level vision that defines the program of works.

Phase E: Opportunities and Solutions

Phase E is well named – it is about finding Opportunities for delivering the Target Architecture by implementing specific Solutions.

Phase E generates the first complete version of the Architecture Roadmap – by combining the analysis and suggestions from the Architecture Development phases – B, C & D
