How Can TOGAF® Help In Extending Enterprise Architecture

Introduction

TOGAF® EA is a framework for developing enterprise architecture using different strategies. It was originally developed by The Open Group Consortium members, and it used to have technical architectures, though the domains for enterprise architectures have already been introduced. It is now a vital approach for developing the necessary strategies for EA development.

Components of TOGAF®

The ADM

The most common component of TOGAF® is the Architecture Development Method (ADM). The ADM is basically the approach used to organize specified tailoring and implementation of enterprise architecture.

The Enterprise Continuum

The TOGAF® Enterprise Continuum is a collection of resources that act as components and elements of the implementation and tailoring of enterprise architecture. These resources pooled are solutions patterns, models, and specific assets. The Enterprise Continuum is equivalent to a reference source for enterprise architecture stakeholders and specialists.

Other than the Enterprise Continuum and ADM, TOGAF® provides extra references and resources related to the methods, solutions and techniques necessary for planning and initiating EA.

Application of TOGAF® and Other Methodologies

TOGAF® should be integrated with a different methodology in the modern business environment.

TOGAF® with the Enterprise Unified Process, EUP

EUP is an approach introduced to help extend the development of EA. It also ushered in new methodologies, including the Enterprise Architecture discipline. When EUP is combined with TOGAF®, it helps to cover a wider approach to the RUP in an enterprise. The approaches of EUP and TOGAF® are different, but they all help in implementing EA.

TOGAF® with RUP

Even though TOGAF® does not share a common scope with RUP, the integration will help create a better EA. The major difference between the two approaches is that RUP focuses on the technology architecture, while TOGAF® focuses on the business architecture.

With the RUP, an organization is able to collect the business prerequisites, which help to design and deploy a software-based system. On the other hand, TOGAF® values IT Service management since it helps an organization discover its vision.

The implementation process of TOGAF® intersects with RUP to achieve EA development. The two intersect when blueprints of architecture, the application model, a top-quality implementation plan, and business architecture are transferred to the execution team. It will only be considered a complete handover if both sides come to an agreement on the implementation scope.

The Enterprise Architecture Scope

The activities of enterprise architecture normally commence prior to the commencement of project-driven solutions. EA will then continue throughout the entire enterprise lifespan. Since it is a continuous process, EA development has one entry point that concurs with the invention of a practice. The entry point also concurs with several process involvements dispersed throughout the enterprise architecture's timeline.

Some EA frameworks introduce iterations and cycles that should accompany the key stages in an organization's business development. In these frameworks, a cycle will entail several stages that feed into the EA activities. This mostly happens in the first stage of the cycle.

Possible Hurdles of TOGAF® Implementation

This approach is a framework, not necessarily an end-to-end approach. For that, it needs an organization's specific tailoring. The customization ignores the business model knowledge and steady methodological knowledge. Given its complexity, using the new version of TOGAF® could be challenging.

It could also be difficult to find a buy-in from a stakeholder that will let you use TOGAF®. Though Framework received many enhancements, it is less comprehensive than other approaches. This is mostly in technology and business connections. For instance, the Framework does not include approaches such as the rational Method Composer. It also does not have a detailed publication library.

So Will It Help In Enterprise Architecture?

An organization needs to decide whether it will be implemented as enterprise architecture. The organization should resolve if it will rely on TOGAF® to implement the EA. The Framework is considered to be the next big tool for the development and implementation of enterprise architecture. Typically, organizations that use the methodologies of the solution lifecycle successfully and uniformly will have better progress in the development of EA. The enterprise architecture must not be forced into an organization by simply making judgments. The need for the EA should come naturally from comprehending the existing complexities that enclose business management. The business structure must also move along with the EA to fit naturally.

TOGAF® is a great tool for implementing enterprise architecture and IT service management. However, it is always advised to give the approach a trial. Also, the organization must fully understand TOGAF® in relation to its business infrastructure.
