Where Does Growth Come From? | Clayton Christensen | Talks at Google

Every job to be done has an architecture of functional, emotional, and social elements, and knowing that mix tells you which features, integrations, and brand experiences to provide.

People underinvest in family and long-term goals because career activities deliver daily, visible evidence of achievement, so scarce time and energy flow to work where feedback and metrics are immediate rather than to parenting whose returns are long-term and unseen.

New technologies like AI tend to be most disruptive when first applied to simple, stable tasks that compete against non-consumption because these uses need fewer complementary changes and can be made affordable and adopted quickly.

Uber was disruptive because its asset-light, variable-cost business model eliminated fleet overhead, leaving asset-heavy taxi incumbents structurally unable to match its cost flexibility.

Whether a technology is disruptive depends on its business model and application because the same technology can be disruptive when used to serve non-consumption cheaply, yet only sustaining when deployed to serve demanding incumbent customers.

Abundant cheap capital combined with ratio-based measurement creates a cycle where firms prefer low-risk efficiency innovations that boost near-term returns, which produces more capital but stalls long-term disruptive investment and broader economic growth.

Measuring performance with ratio-based metrics like RONA or IRR biases firms toward outsourcing and short-term projects because improving those ratios is often easiest by shrinking assets or choosing quick-payoff work rather than funding long-horizon disruptive investments.

Incumbents that successfully pursue disruption create separate business units with different profit formulas and processes because only autonomous units can operate with the low margins and novel practices needed to serve new or unproven markets.
