- A metric that never changes a decision is decoration.
- Definitions must be fixed and documented, or trends become meaningless.
- Six to eight metrics cover most operating companies.
- Trend matters more than level for almost every metric.
- Segment before you aggregate — averages hide the interesting cases.
The test for including a metric
Ask what you would do differently if this number moved twenty per cent in either direction. If the answer is nothing, it does not belong in the pack — it belongs in an appendix, if anywhere.
This test removes about half the contents of a typical finance dashboard, and the remaining half gets read.
A defensible core set
| Metric | Decision it informs |
|---|---|
| Net cash movement | Whether to slow hiring or discretionary spend |
| Runway on committed spend | When to start raising or cut costs |
| Gross margin by segment | Where to focus sales effort, and what to price differently |
| Contribution margin | Whether growth improves or worsens the position |
| Days sales outstanding | Whether collections need intervention |
| Revenue retention | Whether the product is holding its customers |
| Spend per employee by cost centre | Where cost growth is outpacing headcount |
Definitions have to be frozen
Most metric disputes are definitional. If burn includes capital expenditure this month and excludes it next month, the trend is noise and nobody can tell.
Write the definitions down once, including exactly which accounts feed each metric, and change them only deliberately with a note in the report.
- Document each metric's formula and source accounts.
- Note any change of definition in the period it changes.
- Restate prior periods when a definition changes, or the trend is meaningless.
- Keep the same definitions across internal and investor reporting.
Numbers that rarely change anything
These are not wrong, but they seldom drive a decision on their own, and they crowd out the ones that do.
- Total registered users, without an activity qualifier.
- Cumulative revenue since inception.
- Headcount as a standalone metric rather than against output or cost.
- Any average that spans genuinely different segments.
Frequently asked questions
Usually six to eight, with segmentation available underneath. More than that and the pack becomes a document people skim rather than read.
The definitions should not. The selection can differ, but reporting a metric one way internally and another way externally erodes trust the moment someone notices.
Days sales outstanding in service businesses. It is easy to measure, responds quickly to intervention, and directly affects cash — see working capital management.
