Practical TOGAF Case Study

1. Introduction

TOGAF (The Open Group Architecture Framework) is a framework for developing and managing enterprise architecture. This case study focuses on applying TOGAF in a practical scenario, demonstrating how to structure enterprise architecture to achieve business goals.

2. The Case Study

3. Step-by-Step Process

The TOGAF framework consists of several phases, which we'll apply in the context of RetailCo.

3.1 Preliminary Phase

Establish the architecture framework and principles.

3.2 Architecture Vision

Create an architecture vision document that outlines the high-level goals and objectives.

3.3 Business Architecture

Define the business processes and organizational structure.

3.4 Information Systems Architecture

Identify necessary data and application architectures.

3.5 Technology Architecture

Determine the technology infrastructure needed to support the architectures defined.

3.6 Opportunities and Solutions

Identify initiatives to bridge the gap between the current and target architectures.

3.7 Migration Planning

Create a roadmap for execution, including timelines and resources.

3.8 Implementation Governance

Establish governance to ensure compliance with architecture standards.

3.9 Architecture Change Management

Plan for future changes and adaptations in the architecture.
