Complexity is rife in any growing business. As companies innovate, add new business lines and products, or expand their international presence, processes proliferate, and the discipline around them can go out the window. Meanwhile, the IT that underpins these processes can also become more entangled as aging legacy systems jostle with new applications to support the needs of the business. Over time, this kind of complexity can unravel technology standards and undermine the coherence of the architectural blueprint. As application volumes grow in response to a fast-changing economic, regulatory, and business environment, the issue of complexity is becoming acute for many organizations. Enterprise architecture management (EAM), a framework to manage IT architecture and ensure that both the business and IT are well aligned, aims to restore order to this landscape.

Too often, efforts to fix architecture issues remain rooted in a company’s IT practices, culture, and leadership. The reason, in part, is that the chief architect—the overall IT-architecture program leader—is frequently selected from within the technical ranks, bringing deep IT know-how but little direct experience or influence in leading a business-wide change program. A weak linkage to the business creates a void that limits the quality of the resulting IT architecture and the organization’s ability to enforce and sustain the benefits of implementation over time.
