About the Book

The Modern Sourcing Engine — From Build vs. Buy to the BBEC Framework is the first volume of The Agile Enterprise Playbook, a five-book series built on the FOCUS Methodology — an execution-oriented framework for CTOs, enterprise architects, and technology leaders navigating the Gen AI era under GDPR, the EU AI Act, NIS2, and DORA.

"Build vs. Buy" is dead. Every sourcing decision today is a multi-dimensional strategic exercise involving digital sovereignty, vendor lock-in, financial accountability, and AI readiness. This book replaces the binary dilemma with the BBEC Framework — Buy, Build, Extend, Compose — and gives you the full toolkit to execute it:

  • Strategic positioning with Wardley Mapping and Core vs. Context analysis, including EU sovereignty considerations
  • Domain discovery through Event Storming, Value Stream Mapping, JTBD, and MoSCoW interrogation
  • The BBEC verdict engine: Fit/Gap Traceability Matrix, Business Fitness Score, Plugin Test, and open-source "Fork Tax" management
  • Financial modeling that defeats optimism bias: 50/90 range estimation, Capers Jones multipliers, Cost of Delay, and real options
  • Governance via the Architecture Decision Workflow, ADRs with sunset clauses, weighted scoring, and decommissioning discipline

Written for practitioners in or trading with the EU, this is not a theoretical manifesto. Each chapter pairs the theory with a step-by-step methodology and real-world executions — from GenAI customer support agents to fintech scale-ups — so you can move your organization from feature factory to a secure-by-design, compliant-by-default, AI-ready enterprise.

About the Author

Agile Enterprise Media ApS

Lars Shakya Buch-Jepsen is a coding software, ai and data architect with more than 20 years of hands-on experience across enterprise architecture, data warehousing, integration, and cloud engineering. He has served as CTO, enterprise advisor to CTO offices, and today leads the technical branch of DevX, AI & Data at Aeven, helping regulated industries adopt AI, data services, and DevOps under strict compliance regimes.

The FOCUS Methodology was born from years of friction: Enterprise Architecture that was outdated the moment it was written, governance that stopped delivery instead of enabling it, or no architecture function at all — leaving teams to improvise. This book series is the how-to playbook he wished existed: the frameworks, worksheets, and decision workflows to run technology effectively in the age of GenAI, without failing compliance.
