Bringing Clarity and Structure to Organizational Change In today's fast-paced business environment, change is constant and often overwhelming. Navigating shifting demands requires a clear view of the big picture and how decisions shape the future. Without structure, development efforts become fragmented, misaligned, and inefficient. This practical and accessible guide shows how enterprise architecture (EA) brings clarity and coherence to strategy, operations, IT, and development. It introduces a lightweight but powerful framework for managing transformation, aligning initiatives, and helping organizations make smarter, more sustainable decisions-without large investments. Whether your goal is to improve operational efficiency, adopt technologies like AI, or meet evolving regulatory and sustainability needs, this book offers the tools to succeed. Designed for business and IT leaders, architects, consultants, and students, the book is packed with practical examples, actionable advice, and proven models. It helps you start small, focus on value, and scale your EA practice at a pace that fits your organization. No jargon, no unnecessary complexity-just practical guidance that saves time, effort, and money.
