Metrics are never out of fashion. Every wave of software, from business intelligence to dashboards to AI, uses them to get a CEO's attention. Drucker's line endures because it is a principle. The trouble starts when familiarity with the line substitutes for the work.
Metrics exist to assess performance and drive the decisions that improve it. Simple on paper. In practice we see the same three gaps in company after company.
Gap one: no definition
Saying "metrics" conjures competence. The gauge is one small part of a performance indicator. Missing are the target, the data source and the owner. Without those three, you have a number, not an indicator.
Gap two: too many
Pages of reports, good software, the right dashboard, and no consensus on how any of it is used. Collecting data costs time, money and people. If it does not drive a decision, it is waste wearing a suit.
Gap three: strategic and operational mixed together
Every time I see a long list labelled "key performance indicators" I wince. It holds strategic and operational measures with no system fitting them together, and they cannibalise each other: a launch indicator drives new products at the expense of a profitability indicator.
Three fixes
Define the format. Every indicator has a target, a source, an owner and a review date, on one line.
Cut to five. Five Strategic Numbers the CEO watches that tell you, before the quarter does, whether the strategy is working. Everything else is operational, and lives with the function that owns it.
Separate the two tiers. Strategic Numbers are reviewed monthly at the top with root cause on every variance. Operational metrics are reviewed where the work happens. They inform each other; they do not share a page.
Monday
Print your current dashboard. Circle the five numbers that would tell you the strategy is failing three months before the P&L does. If you cannot find five, the dashboard is operational. If you circle more than five, you have not chosen.
