The LeanIX Payoff

Your architecture team produces beautiful diagrams. So why do the big technology decisions still take months, cost too much, and get made without them?
Most enterprise architecture practices drown in documentation no one reads, while the decisions that actually move the business happen in spreadsheets and hallway conversations. The payoff of enterprise architecture was never a prettier diagram. It is a faster, cheaper, better decision.
In The LeanIX Payoff, enterprise architecture advisor Marcus T. Halloran lays out a practical, jargon-light path for turning a sprawling application landscape into a decision engine that leaders actually consult. Drawing on hard-won lessons from portfolio rationalization, mergers, and modernization programs, this book shows you how to make architecture the input that sharpens every major investment, instead of the overhead everyone routes around.
Inside, you will learn how to:
Build a single, trusted view of your application portfolio that people actually use. Identify and eliminate redundant systems to lower IT costs without breaking the business. Tackle technical debt and obsolescence risk before they turn into emergencies. Connect technology spending to business capabilities and real strategy. Build governance that speeds good decisions instead of slowing everything down. Support mergers, acquisitions, and major transformation with clarity and speed. Drive adoption through federation, so the picture stays current on its own. Measure and prove the payoff in terms your CFO and CEO respect.
Whether you are an enterprise architect, IT leader, CIO, CTO, or transformation lead, and whether you run LeanIX, another portfolio tool, or are still escaping spreadsheets, this book gives you the frameworks, checklists, and templates to do the work that matters.
Includes a complete EA maturity self-assessment, an application fact sheet template, a sample business capability map, recommended roles and responsibilities, and a glossary of essential terms.
