The Innovator's Dilemma
Why successful incumbents fail when disruption starts below the mainstream
The innovator’s dilemma (Clayton Christensen) names a structural trap for incumbents: firms optimised to serve existing customers with sustaining innovations struggle to invest in disruptive offerings that initially look inferior on metrics the mainstream cares about — until the disruptor moves upmarket and the incumbent is stranded.
What it explains
- Resource allocation — rational short-term focus on best customers starves embryonic threats.
- Organisational capability — operational capabilities that excel at today’s playbook can block dynamic capabilities needed to pivot.
- Misread signals — early disruptive products look like toys to committees calibrated on sustaining metrics.
What it is not
Not the same as The Innovation Divide: Christensen’s dilemma is about firm strategy and incentives across a market over years. The Innovation Divide is about epistemic honesty in one decision — same evidence, different assigned tier because of build-versus-protect appetite.
Not the same as the chasm: Moore focuses on the gap between early and mainstream segments for a single product’s go-to-market. Christensen focuses on why established companies lose to entrants with different value trajectories.
Corpus stance
A2 — working context: Useful when discussing why organisations resist honest tiering, new capture modes, or architectural change despite evidence. We cite Christensen for the incumbent-structure story, not as a substitute for tier, commitment, or authority facets.
