Why Enterprise Architecture Fails (And How to Fix It)

Enterprise Architecture (EA) is meant to bring structure and strategy to business transformations. However, many organizations struggle to make it work. EA teams often get stuck in endless documentation, disconnected from execution, or rely on outdated information. So, why does EA fail? And more importantly, how can you fix it? 

In this article, we explore the common pitfalls of Enterprise Architecture and offer practical steps to transform it into a true driver of business transformation. 

What is Enterprise Architecture? 

Enterprise Architecture offers a structured approach to managing and transforming an organization’s processes, data, and IT infrastructure to align with business goals. It provides a comprehensive view across architecture domains, such as business architecture, data, applications, and technology, helping organizations make informed decisions about their transformation strategies. 

EA is critical in business transformations, enabling organizations to change and stay competitive. Transformations change how companies operate, driven by market demands, emerging technologies (such as generative AI), or strategic goals. Enterprise Architecture ensures these transformations are effectively planned and executed by aligning business and technology, optimizing processes, and modernizing IT systems: 

• Strategic planning: Identifies and prioritizes which transformation projects to execute and in what order. 
• Supporting project execution: Uses Enterprise Architecture to effectively guide transformation projects by defining necessary changes and creating detailed designs for successful execution. 

The basics of Enterprise Architecture: Understanding your current landscape 

A key part of EA is the architecture repository, which offers a centralized view of the: 

• Business landscape, capturing organizational goals, capabilities, value streams, and roles. 
• IT landscape, detailing applications, data flows, infrastructure, and dependencies. 

By connecting these elements, the repository helps organizations understand how their business functions interact with technology, providing valuable insights and a foundation for future growth. EA frameworks such as The Open Group Architecture Framework (TOGAF) and the Zachman Framework offer structured approaches to implementing enterprise-wide change and ensuring alignment between IT and business strategy. 

Organizations often start their Enterprise Architecture journey by building an architecture repository and creating a shared understanding of the organization's current state. However, they often over-complicate this process. Building out the architecture repository can take considerable time and resources, requiring extensive documentation and coordination across departments, especially when organizations attempt to: 

• Document everything – Instead of focusing on critical areas, they attempt to capture every process and application, even those that rarely change. 

• Provide excessive details – Create overly detailed process descriptions (e.g., Level 1 to Level 4 business processes), which slows down decision-making and adds unnecessary complexity. 

Why Enterprise Architecture fails 

Focusing too much on the current state severely limits the success of the EA team. Investigations with our customers show that this results in three key symptoms:

1. The "Ivory tower" problem

Enterprise Architecture teams become too detached from day-to-day operations. They create strategic plans and governance frameworks but have little impact on actual transformation projects. Without active collaboration with project execution teams, EA becomes an isolated, almost academic function, reducing its relevance.

2. Analysis paralysis

Many organizations spend a lot of time analyzing their landscape, documenting processes, and creating detailed models but never translate these insights into action. The result? Endless analysis with no real business impact.

3. Outdated repository

In a constantly evolving business environment, keeping the architecture repository up to date is a challenge. Studies show that a significant portion of architecture documentation becomes outdated within a year. Without mechanisms to ensure real-time updates, the repository loses value and becomes unreliable. 

What you can do to make Enterprise Architecture work again 

To make your EA team effective, take a pragmatic approach. Here are three steps that you can take:

1. Focus on "Just-enough architecture"

Instead of trying to document everything, focus on the high-level structures. On the business side, focus on: 

• Business Model Canvases – Define how your organization creates and delivers value. 
• Capability Maps – Identify core capabilities and how they interact with IT systems. 
• Value Streams – Map how value flows through your organization and where improvements are needed. 

On the IT side, document only the areas where you expect change. And only focus on high-level descriptions. This approach keeps EA relevant and actionable without unnecessary complexity.

2. Use integrations to automate data collection

Rather than relying on manual updates, leverage integration with: 

• IT Service Management (ITSM) systems like ServiceNow and TOPdesk,  
• data landscape tools like Collibra and  
• process modelling and mining like Signavio and Camunda. 

These tools already store valuable information about applications, infrastructure, data, and processes. By integrating with them, your Enterprise Architecture team can maintain an accurate and up-to-date architecture repository with minimal effort.

3. Ensure that transformation teams use (and update) the same Enterprise Architecture system

The primary reason architecture repositories become outdated is that transformation teams continuously make changes to systems and the organization without updating the central repository to reflect those changes. To fix this, organizations should: 

• Encourage development and transformation teams to actively use Enterprise Architecture, especially when designing solutions. 
• Integrate EA tools with Agile development platforms such as Jira to ensure architecture changes are reflected in real time. 
• Ensure that transformation teams update the repository, once their new solutions and systems are live. This will ensure the repository always shows an up-to-date view of processes, applications, and data landscapes. 
  

Start fixing EA by changing the mindset 

Promote a culture where Enterprise Architecture is seen as an enabler for change, not just a governance or insights function. By taking these steps, EA teams can: 

• Move beyond providing just insights and actively contribute to strategic transformations, driving true business impact. 
• Get buy-in from the organization and be seen as an enabler and value creator rather than a showstopper.
