Slow decisions are not a culture problem. They are an unpriced cost line.
Quantifying decision latency across 40 organisations, with a method for pricing your own.
Slow decisions are not a culture problem. They are an unpriced cost line.
Across 40 organisations we timed the same thing: the interval between a decision becoming necessary and the decision being made and communicated. The median organisation loses nine working weeks a year to decisions waiting in queues — not being analysed, not being debated, simply waiting for a forum with the authority to decide. At mid-market scale that latency prices out between $2M and $14M a year in delayed value, stalled programmes and repeated work.
This brief publishes the measurement method in full. Latency is observable: it can be read out of calendars, approval trails and steering-committee minutes without a single interview. The brief walks through the four highest-cost decision classes, shows the latency distribution across the sample, and prices a worked example so a reader can run the same arithmetic on their own organisation in under a week.
Median working time per year that necessary decisions spend waiting in queues, across the 40-organisation sample.
Median latency for cross-functional decisions — against 4 days for decisions held by a single named owner.
Median annual carrying cost of decision latency in the sample, priced against delayed value and rework.
Share of measured latency attributable to missing decision rights, not missing information.
Time your last ten significant decisions from necessity to communication. That number is your baseline, and it is almost certainly larger than you think.
Separate latency caused by missing information from latency caused by missing authority. In the sample, authority is the larger problem by a factor of three.
Give every recurring decision class a single named owner. Shared ownership is measured here as unowned.
Put the remaining decisions on a fixed cadence, so they wait days for a scheduled forum rather than weeks for an improvised one.
