About the Framework

The Adoptability framework originates from The Cost of Change: The Wall — Why Good Products Fail to Scale, written by Nihat Karaoglu and published by Sustainibility Press.

The framework was developed to answer a single recurring question observed across product launches: if the product works, why didn't the system move? It argues that most product strategy stops at Desirability, Feasibility, and Viability, and misses the governing variable that actually determines whether adoption happens — Adoptability, defined as the condition that Value Captured exceeds Cost of Change for every critical stakeholder in a system.

About the author

Nihat Karaoglu works at the intersection of healthcare, technology, and complex systems, with experience across MedTech, diagnostics, digital health, and enterprise systems in regulated environments. His work focuses on why innovation frequently fails to scale despite technical and clinical success, and on designing products for real-world adoption rather than for approval alone. The framework in The Cost of Change was developed from direct field observation — gemba visits, failed product launches, and the recurring pattern of systems that approved a product without ever structurally adopting it.

Recognition

Geoffrey Moore, author of Crossing the Chasm, featured Karaoglu's work in a guest post on his LinkedIn, describing the cost-of-change framework as "a useful operator's perspective" on why systems resist valuable innovations, building on ideas adjacent to his own Crossing the Chasm model.
