Concept Of Enterprise Architecture ( Ea )

With the IT team, the company needs to develop and define an Enterprise Operating Model and Architecture that include business strategy, current IT assessment, IT strategy and IT plans.

The purpose of this project is to conduct an analysis research into the implementation and management of this business enterprise system. This project deals with developing and upgrading the computer system to handle to daily work load of our business while being able to conduct communication between sites and data back-up. Furthermore, we will analyze other various architectures features such as: system requirements, architecture selection, resources and timeline, security and the

1.In your opinion, what are three main topics of chapter one? How do you know if you have a good foundation?

To consider what enterprise architecture means, it is important to understand its origin. All architecture within information technology can track its ancestry back to the lessons learned from building architecture. Enterprise Architecture is the description and visualization of the structure, a blueprint if you will, of a given area of contemplation, its elements and their collaborations and interrelations links vision, strategy and feasibility, focusing on usability durability and effectiveness. Architecture enables construction, defining principles, rules, standards and guidelines,

1. Given our studies of EA frameworks you are to identify five different criteria by which you can assess the strengths and weaknesses of the: TOGAF, FEA, LightWeight and Zachman framework. (50 points)

An enterprise architecture diagrams are designed during the strategic planning process to strategically picture the organization in the current and future business environment regarding the technology, strategy, and business. The different future scenarios evaluated with the aim of strategically positioning the company to the industry trends through planning, programming, and budgeting (Schekkerman, 2004)).

Enterprise architecture (EA) are implemented to serve two major functions 1) to provide a framework to collaborate between business and IT processes 2) EA provides a crucial link for bringing transformational changes (Knorr & LeClare, 2011).

An Enterprise Architecture Framework (EAF) provides principles and practices for creating and using the architecture description of a system. Frameworks are used to help organizations answer specific question. Enterprise Architecture framework importance is de-emphasized deliberately sometimes. Without a framework though, it is impossible to have foreseeable and repeatable outcomes. There are many EA frameworks out there. However, the four leading ones are The Zachman Framework for Enterprise Architecture, The Open Group Architecture Framework (TOFAF), Federal Enterprise Architecture, and Gartner Enterprise

There are many things that have to happen correctly in the design phase in order for an enterprise-level business system to be effective. In order for the system to be effective, it should align with strategy, reduce costs, improve productivity, promote timely execution, enable better decision making, leverage emerging technologies, ensure acceptable levels of control and risk management, optimize the skills and capabilities of the organization, and promote collaboration across the extended enterprise. (The

Giving a system against which the greater part of your enterprise architecture work is continuously done.

“The primary purpose of Enterprise Architecture is to inform, guide, and constrain the decisions for the enterprise, especially those related to IT investments. The true challenge of enterprise engineering is to maintain the architecture as a primary authoritative resource for enterprise IT planning. This goal is not met via enforced policy, but by the value and utility of the information provided by the Enterprise Architecture.” Source: A Practical Guide to

This holistic approach can be demonstrated through implementing Enterprise Architecture, which is “a comprehensive operational framework that explores all of an organizations functional areas while defining how technology benefits and serves the organization's overall mission.” Enterprise Architecture shows how operating systems, programs, networks, and hardware can be used in every part of the organization to accomplish its objectives (Techopedia).

“Enterprise Architecture” is a term that applies to both a program and a deliverable/output. A company may have an Enterprise Architecture team that is responsible for creating an enterprise architecture. Considering everything you have read, discussed, and learned in this program, (a) describe the ‘Enterprise Architecture’ discipline or program, (2) describe the ‘enterprise architecture’ deliverable/output.

The enterprise architect must always be in communication with various stakeholders in the organisation to gain an insight and an understanding of the organisation’s culture, technologies, processes and dynamics. (Daniel, 2007) “Enterprise architecture focuses on 4 crucial C’s, namely, connection, communication, collaboration, customers”. Therefor the role of an enterprise architect entails having a myriad of qualities, solid knowledge of technologies and business processes and operations. An Enterprise architect is responsible for ensuring the completeness of the organisation’s IT architecture, and the overall management of the process that determines the technology direction to support the business

Although we know they EA = Strategy + Business + Technology, but that no means the top level managers know. It is because the lack of experienced enterprise architects in the Companies (Seppanen et al., 2009).
