A company looking for the right EAF must know that these frameworks vary widely , with some providing more structure around the taxonomy, classification, or organization of an enterprise. On the other hand, others emphasize process.


As some experts point out, EAFs can vary from processes or full-blown methodologies to more flexible practices. In certain comparisons, EAFs are very similar and repetitive, and others have little in common beyond the name of enterprise architecture framework.

Historically, the frameworks tend to offer similar processes to follow when implementing an enterprise architecture, yet there were some problems with these so-called solutions:. Still, maintaining the documentation is often too cumbersome and time consuming. What is documented, companies find, could be poor in quality and detail, or too quickly outdated to be useful.

Indeed, more recent opinions hold that the demand for EAF is growing, but the challenge to EAF may not be the frameworks themselves, but the way we understand them. While these frameworks are often rigid and structured, which might not align with constant change inherent in 21 st century business and technology, using the frameworks as guidelines instead of as gospel may prove beneficial — after all, companies still need a structured approach to infrastructure.

The harder part, indeed as with a lot of technology, may be convincing the company at-large that this approach works. As most employees are so focused on the implementation of a single tool or application, they might not see the benefit of a holistic approach that enterprise architecture can provide.

Despite the criticism of guiding frameworks, technology experts and companies often agree that the structure the enterprise architecture provides can be beneficial, and indeed necessary.

Whereas a framework has the potential to muddy the waters, a skilled enterprise architect — the person responsible for this holistic vision come to life — may be exactly what a company needs. Enterprises often employ an enterprise architect whose responsibility includes the overall alignment of IT and business needs to achieve business strategy.

After all, frameworks are static pieces of guidance for businesses and technologies are constantly shifting.

A successful enterprise architect is able to understand all the moving parts and relationships within a business, not only within the IT sector of an enterprise. This holistic approach must include strategy, enterprise architecture, and even project delivery to ensure success.

Some proponents of EAFs even see that enterprise architecture can bridge the gap between the IT and business silos that often exists within companies.

A strong enterprise architect, then, must be able to collaborate as easily with developers as with senior management. Hard skills that a good enterprise architect can make use of include knowledge of network administration, traditional systems admin, and even cloud admin; systems thinking and project management; IT governance; and hardware and software knowledge.

As more and more companies move to the cloud and embrace the flexibility that comes with a DevOps culture, two real things will happen:. This digital transformation equates to a more and more complex project landscape , one in which customers expert — perhaps demand — to use various channels interchangeably and with equal success, often during a single transaction.

A holistic framework to enterprise architecture may be the answer. One area that enterprise architecture will undoubtedly need to grapple: Smartphones have revolutionized the way the public accesses software — simply go into the app store, click, download, and begin using. Users can download, delete, and re-download apps exactly when they need them. But experts question how this download-and-go attitude will affect a holistic enterprise architecture where things are heavy and significantly less speedy.

There is little success for plug-and-play options in a large enterprise architecture, but will this need to change? At their best, successfully adopted EAFs can bridge the gap between the IT and business worlds — in doing so, the way an organization views and achieves IT can be vastly improved.

Defining the Enterprise Architecture Framework Simply stated, enterprise architecture framework EAF refers to any framework, process, or methodology which informs how to create and use an enterprise architecture.

So, what is enterprise architecture? History of EAF A commonly held tenet is that enterprise architecture frameworks date to the mids, in accordance with the publication of the Zachman Framework, developed by then-IBMer John Zachman.

A researcher of 20 th — and 21 st -century technology, Svyatoslav Kotusev says that we can look at the history of EAFs in three smaller eras: It included both a top-down planning approach and an architecture planning process that was divided into a series of steps for a company to follow. The plan, with diagrams and matrices to illustrate its system, can be traced through all EAFs even today. Overall, these approaches focused strictly on technical infrastructure , like how to deploy hardware and servers.
