About the Book

Continuous Evolution — REAP, FinOps, and Architecture Debt is the fourth 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.

The static IT audit is dead. The digital portfolio is a living organism that requires continuous pruning, scaling, and financial optimization — and the Gen AI transition is won or lost on your ability to fund it by ruthlessly retiring legacy debt. This book replaces obsolete, annual-audit governance with dynamic portfolio disposition, giving you the full toolkit to execute:

  • REAP (Reassess, Extract, Advance, Prune) for continuous portfolio evaluation and disposition
  • Quantifying Enterprise Architecture Debt mathematically, through the detection of EA Smells
  • Compliance debt: exposing legacy systems that cannot meet GDPR or NIS2 logging requirements
  • FinOps: from aggregate cloud spend to precise cloud unit economics
  • AI unit economics: the ROI and token-burn rates of Gen AI inference

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 turn your portfolio from a legacy cost sink into a self-financing engine that funds its own AI evolution.

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The FOCUS Methodology was born from years of friction: Enterprise Architecture that was outdated the moment it was written, governance that stopped delivery instead of enabling it, or no architecture function at all — leaving teams to improvise.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.
