Time-Saving Bias

You're seeing Time-Saving Bias when a team invests heavily in optimising a process that's already fast — shaving seconds off a 2-minute task — while ignoring a slow, manual process that takes 2 hours. The fast process feels like low-hanging fruit, but the slow process offers far more recoverable time.

You're seeing Time-Saving Bias when engineers estimate that cutting build time from 10 minutes to 5 will "save as much time" as cutting it from 60 minutes to 30. The absolute savings are different; the proportional savings are the same — but the intuition treats them as equivalent.

Audit where your team spends its optimisation effort. Time-saving bias pulls teams toward polishing already-efficient workflows while neglecting the slow, unglamorous processes that cost the most aggregate time. Build the habit of calculating absolute time saved before committing resources to any efficiency project.

Smith built FedEx on a precise understanding of where time savings actually mattered. While competitors optimised individual truck routes — shaving minutes off already-efficient legs — Smith redesigned the entire hub-and-spoke system to eliminate the slowest bottleneck: regional sorting. His insight was that the greatest time savings came from attacking the slowest part of the system, not polishing the fastest. Founders can apply this by resisting the pull toward visible, incremental optimisation and instead identifying where the largest absolute time losses occur. Smith proved that the biggest efficiency gains come from fixing what's genuinely slow, not from making what's already fast slightly faster.
