The goal of enterprise architecture is to create a unified IT environment (standardized hardwareand software systems) across the firm or all of the firm’s business units, with tight symbioticlinks to the business side of the organization (which typically is 90% of the firm as seen earlier,at least by way of budget) and its strategy. More specifically, the goals are to promote alignment,standardization, reuse of existing IT assets, and the sharing of common methods for projectmanagement and software development across the organization. The end result, theoretically,is that the enterprise architecture will make IT cheaper, more strategic, and more responsiveThe purpose of enterprise architecture is to create a map of IT assets and business processes anda set of governance principles that drive an ongoing discussion about business strategy and how itcan be expressed through IT. There are many different suggested frameworks to develop an enterprisearchitecture, as discussed later on. However, most frameworks contain four basic domains,as follows: (1) business architecture: documentation that outlines the company’s most importantbusiness processes; (2) information architecture: identifies where important blocks of information,such as a customer record, are kept and how one typically accesses them; (3) application systemarchitecture: a map of the relationships of software applications to one another; and (4) the infrastructuretechnology architecture: a blueprint for the gamut of hardware, storage systems, andnetworks. The business architecture is the most critical, but also the most difficult to implement,according to industry practitioners [KOC200502].
