Enterprise Architecture delivers its greatest value when it is understood and used as a decision support system rather than as a documentation or modeling exercise. In this framing, architecture exists to help leaders make better enterprise decisions in pursuit of defined outcomes. Models themselves are not the product. Decision insight is the product.

At its core, Enterprise Architecture translates complexity into clarity. Modern enterprises are systems of interdependent capabilities, processes, technologies, data, and people. Decisions in one area inevitably affect others, often in ways that are not immediately visible. Enterprise Architecture provides a structured representation of this system, enabling leaders to understand the enterprise-wide implications before committing resources or direction. 

In today's complex enterprise landscapes, organizations struggle to maintain alignment between high-level strategy and operational execution. With multiple stakeholders, competing priorities, and ever-changing technology, ensuring a clear connection between strategic goals and execution can be daunting. This is where line-of-sight (LoS) models play a pivotal role in enterprise architecture.

LoS models bridge the gap between vision and execution, offering a structured approach to linking strategic intent with business processes, applications, data, and technology infrastructure. They provide a clear, top-down or bottom-up view, helping stakeholders at different levels understand how various enterprise elements contribute to overarching objectives. 

Enterprise Architecture (EA) often conjures images of intricate diagrams and complex models, but its true essence lies beyond these artifacts. At its core, EA models are not the end but are part of a powerful tool for informed decision-making. The real value proposition of EA is its ability to provide decision insights, enabling decision-makers to navigate the complexities of modern enterprises with greater effectiveness and agility.
