Clayton Christensen
Notes
Clayton Christensen
One-line summary: Harvard Business School professor (1952-2020) who originated the theory of disruptive innovation — influential as a directional lens, contested as a predictive one.
What it is
Christensen's The Innovator's Dilemma and subsequent work introduced disruptive-innovation: the pattern by which entrants take footholds in low-end or new-market segments incumbents cede, then improve up-market until they displace them.
Why it matters here
His theory is one of the four named pillars of the "disruption toolkit" this thread covers, and it supplies the qualitative direction of a disruption. But the academic literature is sharply divided on whether it predicts — the reason this thread treats it as a framing device, not a numeric forecasting tool.
Key facts
- Theory broadly validated for some core concepts, especially in developed-world contexts (Madhusudan et al. 2022).
- Heavily critiqued for definitional ambiguity, inconsistent unit of analysis, and neglect of managerial agency (Weeks 2015, following Jill Lepore's critique).
- A 2024 synthesis frames its value as possibly more performative than predictive (Lile et al. 2024).
