The measurement that did not exist

Whatever you decide to change, you need to know what the number was before. Without a baseline you have an anecdote, and an anecdote will not survive the first conversation with the person who built the business — nor should it, because you will not know yourself whether it worked.

Choose one thing and make it something the business already cares about: days to collect payment, jobs completed per week, stock turns, hours of rework, enquiries that turn into customers. One measure, not a dashboard. Then measure it for two weeks before touching anything, using whatever is already there — the order book, the register, the bank statement, a tally on paper. It does not need a system, it needs to be honest and consistent.

Two rules make a measurement survive. Someone must own it by name, or it stops the week you are busy. And it must take under five minutes a day, or it stops for the same reason. A measurement that dies quietly is worse than none, because the next person to propose one has to overcome the memory of the last one that fizzled.
