Why small gains compound

Marginal gains is catnip for organisations that enjoy optimisation more than decisions. It sounds scientific, keeps everyone busy and never requires the awkward admission that the strategy may be wrong.

Still, once the direction is sound, tiny improvements are wonderfully unfair. Remove one baffling field from a checkout and the benefit repeats with every customer. Make sales notes two minutes clearer and every later handover inherits the saving. Give a new user one useful result five minutes sooner and the whole onboarding journey starts from a better mood. Nobody unveils these changes beneath dry ice. They just keep paying rent.

The order matters. First decide whether the bicycle is heading towards the right bloody town. Then polish the bearings. A sharper subject line cannot rescue an irrelevant offer; a faster approval process merely accelerates nonsense if the work should not exist. Small improvements are multipliers, not substitutes for choosing a worthwhile destination. I would keep two lists: big assumptions that could make the entire plan wrong, and small frictions repeated often enough to matter. Attack the first list without sentiment. Then let the second compound quietly. Heroic launches get the applause because they happen on a date. Good systems win because they happen every day.
