The Best Method for Enterprise Architecture Analysis or Evaluation

Enterprise architecture (EA) is pivotal to the strategic success of any organization. It involves a systematic approach to designing and implementing an organization's architecture to support its business objectives and processes. There are various methods and tools available to undertake EA, each with its own strengths and weaknesses. This article discusses three popular approaches, their benefits, and suitability for different contexts. By understanding these methods, you can make an informed decision on the best approach for your organization.

1. Implementing a Framework

One of the most structured approaches to EA is selecting and implementing a framework. frameworks like the TOGAF (The Open Group Architecture Framework) and Zachman Framework provide a comprehensive and detailed guide to EA. These frameworks outline processes, tools, and best practices for EA management. Implementing a framework can be highly beneficial as it ensures consistency, traceability, and alignment with the organization's goals.

TOGAF and Zachman are highly versatile and can be customized to fit various organizational needs. They offer a wide range of tools and processes, including a robust set of templates, checklists, and guidelines. However, the downside is that these frameworks can be complex and costly, especially for smaller organizations. They are designed to handle large, complex enterprise environments and require significant investment in training and resources.

2. Outsourcing to an Audit Firm

If your organization lacks the internal resources or expertise to undertake EA, outsourcing to a professional audit firm is another viable option. Firms like Deloitte, PwC, and Accenture offer comprehensive EA audits and assessments. These firms bring a wealth of experience and industry knowledge to the table, ensuring a thorough and accurate evaluation of your enterprise architecture.

An EA audit by these firms can be particularly beneficial for organizations that need an unbiased and comprehensive review of their current architecture. While the cost can be significant, the expertise they bring can provide valuable insights and recommendations for improvement. The main downside is the reliance on external consultants, which can sometimes lead to a loss of control and alignment with internal processes.

3. Hiring a Chief Enterprise Architect

For organizations that want to build a robust and sustainable approach to EA, hiring a chief enterprise architect can be the best long-term strategy. A skilled chief architect can lead the development and implementation of an EA framework, driving alignment between IT and business objectives. They can also develop and maintain an EA platform or tool to support the organization's needs.

Hiring a chief enterprise architect requires a significant investment, but the benefits can be substantial. The architect can provide ongoing guidance, ensure consistency in implementation, and drive the evolution of the architecture over time. However, finding the right person with the right combination of skills and experience can be challenging, and there is a potential risk associated with anchoring your strategy to a single individual.

Popular EA Tools and Platforms

Several tools and platforms are available to support EA, each with its unique features and benefits:

Megaworld: A highly popular, proprietary solution with diagramming capabilities. It is a robust platform that can handle complex enterprise environments but comes at a high cost. It is best suited for large organizations that can allocate significant resources to support its implementation and maintenance.

Avolution Abacus: A very methodical and configurable tool. It allows users to configure any meta-model element and offers diagramming capabilities. The cost is medium, making it a more accessible option than Megaworld. It is ideal for organizations that require a highly customizable and detailed approach to EA.

Orbus IServer: This platform is friendly with Microsoft tools and formats and can be integrated with Visio and documents. It revolves around documents and offers diagramming capabilities at a medium cost. It is best suited for organizations that already have a Microsoft ecosystem in place.

Alfabet: A powerful tool with in-depth business process coverage. It offers robust diagramming capabilities and is quite costly. It is an excellent choice for organizations that require a comprehensive and detailed EA approach.

Known for their open-source options, these tools offer less diagramming but more customizable dashboards. They are cheaper and provide full control over the meta-model, making them ideal for organizations that prioritize flexibility and cost-effectiveness.

LeanIX (SAP-acquired): A workbench platform that offers some out-of-the-box intelligence and dashboards. It has fewer diagramming capabilities and is costly. It is best suited for organizations that need a scalable and intelligent EA platform.

Sparx EA: This very old and popular platform is a modeling tool in itself. It is extremely detailed but also very costly. It is suitable for organizations that require a highly detailed and methodical approach to EA.

Conclusion

The best method for enterprise architecture analysis or evaluation depends on the specific needs and context of your organization. If you have the resources and expertise, implementing a framework or investing in a chief enterprise architect can provide a robust and sustainable approach. If you lack the internal resources, outsourcing to an audit firm can be a practical solution. Ultimately, the choice should align with your organization's goals, budget, and long-term strategy.
