INTRODUCTION

English translation pending.

CORE DEFINITION

When incumbents face a disruptive innovation, fear of losing the existing business supplies the motivation to change, but rigid routines and legacy resource-allocation logic distort how the new venture is built. The incumbent moves early yet arrives late, because the new business is turned into a defensive shield for the old one instead of an independent species. The result is defensive innovation, a venture that exists only to protect the core and therefore lacks any independent logic for survival.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Name the motive: ask whether the new project is driven by fear or by a real independent thesis. - Isolate the venture: set up a separate unit outside the old metrics and resource logic. - Measure differently: judge the early venture by growth rather than legacy profit measures.

Anchor fast decisions

The incumbent's routines, performance metrics and resource allocation are all optimized around the core business. Fear triggers action, but path dependence forces the new venture into the old framework, where legacy channels and margins assess it. The innovation is then diluted into a defensive layer protecting the core, and since it never gains an independent survival logic, the original window closes before the venture can capture it.
