A weekly report ran to page after page of charts, and nothing was decided after reading it. The assumed problem was missing data. The real one: not one number was attached to a decision. It happens with a single number too. A team gets its customer satisfaction score and treats it as the answer, but the scale only sorts people into promoters, passives and detractors — it never says why they answered that way or what to change. Measurement stopped at the score: nobody listened to the reasons, chose an action, or came back to see if it worked. Set the target, measure, analyse the causes, choose one owned action plan, improve, then measure again. And do not ask customers for feedback unless someone intends to act on it. The score starts the work; it is not the result.
Don't bother with a metric if it produces no business insight or action.
Grouping only. No reason, no action.
Then back to the top with the next score. A number that changes nothing is not measurement.
