Enterprise Architecture Interview Questions

In the process of interviewing for an Enterprise Architect position, some fairly common questions are asked. You should practice the answers to these questions so that they sound well thought out and your answer is easy to understand.

1. What is Enterprise Architecture?

An Enterprise Architecture is a collection of strategic information that describes a business and the information and technologies necessary to operate the business. This includes descriptions of goals, business processes, roles, organizational structures, information, applications and systems. It is a process that encapsulates the information necessary to implement new technologies in response to the changing needs of the business.

2. What are the Four Domains of Enterprise Architecture?

Enterprise Architecture is often broken down into four domains: application, data, technology, and business architecture.

3. What is the value of Enterprise Architecture?

Enterprise Architecture is a strategic information asset that is used to shape the entire Enterprise. It is essential for efficiently planning and directing future IT investments, as well as understanding the current investment in technology. Enterprise Architecture helps achieve enterprise alignment, manage change, and reduce time-to-market.

4. What is the TOGAF framework?

The Open Group Architecture Framework (TOGAF) is a framework for enterprise architecture. It provides a comprehensive approach to the design, planning, implementation, and governance of an enterprise architecture. TOGAF models the enterprise at all four domain levels: Application, Data, Technology, and Business.

TOGAF includes a methodology for defining IT in terms of a set of building blocks. It also contains a set of tools, a vocabulary, recommended standards and list of TOGAF compliant tools.  TOGAF includes a iterative process for enterprise architecture called Architecture Development Method (ADM).

5. What is the Zachman Framework?

The Zachman Framework is a framework for Enterprise Architecture developed by IBM in the 1980s. This framework has been incorporated into many Enterprise Architecture frameworks. It provides a way of defining an enterprise according to a 6×6 matrix of architecture documentation. The columns of this matrix ask the questions why, how, what, who, where, when. The rows look at these questions from different levels of detail: contextual, conceptual, logical, physical and detailed.

The Zachman Framework provides a view for Planners, Owners, Designers, Builders and Subcontractors. The basic idea is that the same thing can be described for different purposes in different ways.

6. What is ITIL?

Information Technology Infrastructure Library (ITIL) is a set of best practices for IT service management, development and operations. ITIL gives detailed descriptions of a number of important IT concepts and includes checklists, tasks and procedures that can be tailored for any enterprise. This standard was initially developed to align with the service management best practice specifically defined by ITIL, but can support other IT Service Management frameworks.
