While Enterprise Architecture (EA) and Business Architecture (BA) define what needs to be done, planning defines when Enterprise Architecture Frameworks and Business Architecture Frameworks will be implemented. Enterprise Architecture and Business Architecture planning is the process of defining architecture for the use of information in support of the business and the plan for implementing them.
In a top-down approach, EA and BA approach the business processes plan, develops the IT plan or the applications plan and a plan to better align business with IT, called a functional plan. Planning EA and BA is critical to a company's performance. It can benefit an organization in several ways: identifies gaps between baseline and targeted states and recommends a sequencing plan to bridge the gap, helps in information sharing across the board and helps to track performance and minimize overall costs.
Architecture Life Cycles Explained
Life cycle is the basic planning format applied to Enterprise Architecture or Business Architecture and strategic planning. Within an Enterprise Architecture Life Cycle (EALC) or a Business Architecture Life Cycle (BALC), different activities in the project are implemented in a timely and effective manner.
There are several activities involved in Enterprise and Business Architecture planning.
-
First is to envision and define the scope of the architecture environment.
-
Second is to identify key stakeholders.
-
Third is to create a business case for systems and finally to create the project and
evaluate and maintain it.
The various steps in an EALC or BALC are:
-
EA or BA Development
-
Portfolio Management
-
Project Management
-
Solution Delivery and
-
Organization Change Management.
These are the broad areas that must be looked into in order that Enterprise Architecture or Business Architecture and system development go hand in hand.
All large companies plan, develop, test and install software systems to rely on their information and data needs. A system is essentially a set of processes by which an organization achieves its objectives. No system functions in a vacuum. They coexist with numerous other systems in an organization.
Architecture and system development is concerned with the fact that every system in an enterprise must not only fit in, but should also reflect the strategy and vision of the business.
Within an Architecture life cycle, a given application must be developed so as to take advantage of a shared infrastructure. It should not adversely affect other systems in an organization.
