About the Book
Lean Enterprise Architecture (LEA) is a modern, practice-oriented guide to mastering Enterprise Architecture in a fast-moving, digital world.
Enterprise Architecture (EA) is no longer a static blueprint exercise. Today, it is a dynamic leadership discipline—one that connects strategy with execution, business with IT, and innovation with governance. This book equips you with the skills, tools, and mindsets needed to practice EA as an enabler of value creation, transformation, and sustainable impact.
Built on the curriculum of the CAS Enterprise Architecture program at HSLU, LEA offers a structured learning journey that blends theory, frameworks, and hands-on methods. Each chapter is mapped to real-world competencies and supported by case studies, exercises, and reflective practices—designed to make EA relevant, actionable, and human-centered.
You will learn how to:
- Frame EA strategically as a steering instrument for the enterprise.
- Design Business Architectures that align capabilities, value streams, and customer focus.
- Drive IT-Transformation and organizational design with proven frameworks and patterns.
- Apply modeling, visualization, and decision techniques to communicate with clarity.
- Explore technology and system architecture trends—from cloud to AI, DevOps, and platforms.
- Act as a change agent: leading stakeholders, telling compelling EA stories, and building trust.
- Leverage EA tools, governance, and operating models for measurable impact.
Who is this book for?
This book is written for enterprise architects, business architects, IT strategists, digital leaders, and transformation professionals who want to sharpen their EA practice. It is equally relevant for business-oriented and IT-oriented readers who seek to bridge strategy, architecture, and execution in a lean and pragmatic way.
Why this book?
Because the world of EA is evolving. Organizations need more than frameworks—they need adaptive architects who combine strategic insight with practical skills, and who can lead with influence rather than documents. LEA provides exactly that: a competence-based, interactive, and reflective approach to Enterprise Architecture for the 21st century.
