I’m a relative newcomer to the ideas behind disruptive innovation (when Clayton Christensen first published The Innovator’s Dilemma, which provides an evidence-based framework for how new entrants to a market can displace the incumbents by introducing products and services that compete asymmetrically, I was still at school).
When I did, eventually, come across Christensen’s work, I could probably have skipped over the majority of the evidence part; as a market researcher in the tech sector, I only had to look around at the changes taking place in the computing and telecoms markets.
