During the early days of computing, the new technology simply automated the contemporary manual processes with increased efficiency. As the new technology continued to evolve, new innovations paved the way for introduction of new processes and capabilities that were largely driven by information technology. Over time, information technology altered the business environment though not necessarily in conformation with the conventional business strategies. The resulting lack of alignment precipitated unanticipated loss of resources and missed opportunities, thus placing ...view middle of the document...

An enterprise architecture framework typically encompasses the following:

• Principles, processes, tools, and strategies

• Models, taxonomy, and common vocabularies

• Models and reference architectures

• Prescriptive guidance

A strategic plan refers to a document that guides the business’s process of outlining its direction, or strategy, and make succinct decisions while allocating its resources in the pursuit of its goals and objectives.

The introduction of several enterprise architecture frameworks has been hailed as a major breakthrough in streamlining the running of businesses in today’s competitive business environments. These frameworks include: Federal Enterprise Architecture, Open Group Architecture Framework (TOGAF), Zachman’s framework, Standards and Architectures for e-Government Applications (SAGA), Modeling Framework for Collaborative Networked Organizations (MFCNO), and the Governance Enterprise Architecture (GEA). For an organization dealing in the provision of information technology services, the two most appropriate enterprise architecture frameworks are the Zachman’s framework and the Open Group Architecture Framework (Bernard 2012)

Zachman’s Framework

This enterprise architecture framework is modeled towards the provision of a logical structure that can be utilized in the classification and organization of descriptive representations of a given enterprise. This framework model aligns the representations of an enterprise framework into columns and rows. The rows depict the roles or perspectives involved in the definition of an enterprise framework. These roles include: owner, planner, builder, designer, and the subcontractor. On the other hand, the columns represent the questions that each architectural representation is supposed to answer. These questions include: How, When, What, Who, and Why (Zachman, 2006).

The Open Group Architecture Framework (TOGAF)

The goal of this framework is to aid in the design, evaluation, and development of Enterprise Architectures for a business organization. This framework attempts to offer a technology-and-tool- neutral organizational standard for creating Enterprise Architectures that are complementary to other established enterprise architecture frameworks.

For an organization that operates on an information technology platform in the development and distribution of its medical device products, The Open Group Architecture Framework is preferable as it is anchored on a model of Resource Base and an Enterprise Continuum. The Resource Base comprises a set of templates, guidelines, background information, and many more. These resources help the organization’s enterprise architect in the utilization of the Architecture Development Method. On the other hand, the Enterprise Continuum is basically a repository of the entire architecture assets that exist within the enterprise and in the larger information technology industry. This particular...
