How To Implement Enterprise Architecture

In previous articles we explored the Who, What, Why, Where and When of Enterprise Architecture. In this final instalment of our series on Enterprise Architecture, we look at “How to implement Enterprise Architecture”. For the other articles, we presented a general perspective but for this last piece, our approach is to present something specific to ATD because this article deals with how we help companies to successfully implement Enterprise Architecture.

Our approach to Enterprise Architecture is called ATD GREAT, which is short for Governance and Realisation of Enterprise Architecture Transformation. It is a six-pronged approach that guides organizations in their journeys towards enterprise transformation:

i) AREA (Enterprise Architecture readiness assessment)
ii) GEAR (Enterprise Architecture governance)
iii) BRAM (Business Requirement Architecture & Management)
iv) LEAD (Enterprise Architecture development)
v) REAL (Enterprise Architecture implementation through PMO)
vi) MEAL (Enterprise Architecture maturity assessment)

six-pronged approach that guides organizations in their journeys towards enterprise transformation

A brief description for each of the ATD GREAT components:

ATD AREA (Assessment of Readiness for Enterprise Architecture)

Enterprise architecture readiness assessment is an organization’s health check that identifies areas that need to be improved or fixed prior to adopting Enterprise architecture. This is achieved through multiple assessment sessions that cover various Enterprise Architecture Readiness Factors. It will all be documented together with the necessary action steps and recommendations on what needs to be done in order to achieve successful Enterprise architecture Implementation.

ATD GEAR (Governance of Enterprise Architecture and Regulation)

ATD GEAR, which is adapted from the TOGAF Governance Framework model, provides a governance framework that integrates seamlessly with ATD LEAD and ATD REAL (more on that later) to provide the necessary support for effective implementation of Enterprise architecture by applying COBIT5 as the world’s best practice of Business IT Governance implementation.

ATD BRAM (Business Requirement Architecture & Management)

For any Enterprise architecture initiative to be successful, it is necessary to capture the “concerns” and then matching the “needs” and “wants” of stakeholders. This is all about getting the right business requirements using business scenario techniques and allowing stakeholders to evaluate and update these requirements as accurately as possible. A sound Business Requirement Architecture approach will ensure that requirements must thoroughly consider every possible business scenarios.

ATD LEAD (Lifecycle of Enterprise Architecture Development)

ATD LEAD, based on best practices from the Architecture Development Method from the Open Group, tailors the framework provided in TOGAF to the specific needs of the enterprise. Unlike an academic approach to TOGAF, this method has customized steps to deliver the greatest value without overwhelming the organisation with information overload and unnecessary red tape. The outcome of this process will be the Architecture Building Blocks: Business Architecture, Data Architecture, Application Architecture and Technology Architecture.

ATD REAL (Roadmap of Enterprise Architecture Live)

Kicking in at the conclusion of the development lifecycle, ATD REAL sets the platform roadmap for future project initiatives that will utilize the Architecture Building Blocks developed through ATD LEAD. It prioritizes and consolidates requirements across enterprise business sections and interoperability requirements across architecture domains for integrated development and deployment of the new capabilities. The output of this process is a list of prioritized projects, based on the IT Architecture Return of Investment (ITA-ROI) as well as Risk Management Techniques, to be realized by the Project Management Office and solution architects.

ATD MEAL (Maturity of Enterprise Architecture Lifecycle)

The assessment for the Maturity of Enterprise architecture Lifecycle is an organization health check that allows stakeholders to objectively assess the progress of the organization’s Enterprise architecture development. It is based on the enterprise Architecture Capability Maturity Model (ACMM) that was first developed by the US Department of Commerce for conducting its internal Enterprise architecture assessments. This is basically a framework that represents the key components of productive Enterprise architecture processes that can identify areas of weakness so that more focus and attention can be given to improve the overall Enterprise architecture process.

In a nutshell, ATD GREAT is an approach that will cut across organizational boundaries, tackling the challenges of lack of visibility and communications that occur in many organizations. It will ensure the alignment of an organization’s business strategy goals with its IT solutions in a way that is effective (satisfying the right business requirements), efficient (optimum resources), economical (minimum cost) and carries with it the desired business values (ROI, TCO and P&L). It is our proven method for successfully implementing Enterprise architecture.

Where To Start With Enterprise Architecture

Traditionally, Enterprise Architecture has been used to document the design of an organization – from its operations and business process to its systems and IT – and then to use that information to reduce complexity, increase collaboration and improve productivity.

Why Enterprise Architecture

Digital transformation can help companies become more efficient, productive and agile, thus making them capable of delivering new and innovative products and services in a timely manner. But digital transformation is not easy to achieve. Traditional brick and mortar companies have existing business models, technology systems and operational processes that are already deeply ingrained.
