This document discusses different trajectories that technology capabilities and customer acceptance can take over time. It identifies four trajectories: 1) deceleration due to decreased investment, where capabilities fall behind customer needs, 2) accelerating improvement where capabilities outpace customer needs if not matched with new markets, 3) step-function improvement where disruptive technologies create new uncontested markets, and 4) limitation where capabilities fail to keep up with changing customer requirements and market needs. The key is for technology capabilities and customer acceptance to remain aligned over time.
