A Clearer Way to Map Enterprise Architecture

Introduction

In complex IT landscapes, having a clear and structured view of the enterprise ecosystem is essential for informed decision-making. Over the years, I have developed and refined a template using ArchiMate modeling to provide stakeholders with a high-level overview of their organization's IT landscape.

This template has been successfully used across multiple projects to streamline knowledge transfer during the Transition & Transformation (T&T) phase. It helps teams visualize dependencies, navigate system architectures, and ensure alignment between business capabilities and technology solutions.

Purpose of the Diagram

The diagram below serves as a high-level snapshot of an organization's IT ecosystem. It allows stakeholders to quickly grasp the scale and structure of applications, vendors, technologies, and user groups within the enterprise.

Key Components Explained:

• Stakeholders

1. Internal and external users who interact with the ecosystem.
2. Helps in understanding user impact and access needs.

• Business Capabilities

1. Represents the functional areas of the business supported by IT systems.
2. Provides clarity on how IT solutions align with business objectives.

• Applications Layer

1. Groups various enterprise systems and modules.
2. Helps in tracking dependencies, scalability, and integration points.

• Vendors

1. Shows external vendors and their associated applications.
2. Helps in understanding third-party dependencies and vendor management.

• Technology Layer

1. Lists the core technologies (programming languages, cloud services, frameworks, and tools) supporting the applications.
2. Provides insights into technology diversity and modernization opportunities.

Why This Template is Useful

?? Supports Strategic Planning – Provides a clear navigation path from high-level views to detailed insights.

?? Accelerates Knowledge Transfer – Aids in onboarding teams during project transitions.

?? Enhances Decision-Making – Helps architects and leadership align business needs with IT capabilities.

Final Thoughts

This template has proven to be an effective tool for simplifying complex IT landscapes and improving stakeholder engagement. By providing a structured, layered approach, it supports a more cohesive and strategic enterprise architecture.
