Business leaders and managers are expected to not only understand the goals of their organizations but also effectively collaborate with technical teams throughout the Software Development Life Cycle (SDLC). Design Phase – Business Architecture and System Architecture is an essential resource designed to help leaders actively engage with consultants and technical staff during this pivotal stage.

The book explains the use of enterprise and business architecture frameworks, such as the Zachman Framework, to provide clarity on how different components of a business—data, function, people, network, and motivation—are represented and modeled in system design. The book emphasizes the role of business leaders in system architecture and details how their involvement can impact system design from defining business requirements to participating in governance and decision-making.
