Practical guide
Make management metrics comparable
Define the calculation and comparison before interpreting a movement.
Write down the definition
Define the numerator, denominator, time basis and included statuses. Sales orders, invoiced sales and collected cash answer different questions. Record whether a value includes tax, returns and discounts, and whether overdue means past the invoice due date or a separate agreed date.
Compare like with like
Use comparable periods, branches and customer sets. Separate a genuine change from a changed data feed or newly included business unit. Compare currencies only using an agreed rate and conversion date; public website currency examples do not change your workspace accounting currency.
Inspect what drives the total
Break a movement into supporting records. Look for concentration in a few customers, products or transactions. Check whether a missing source, reversed entry or late update explains the movement before assigning a business cause.
Assign a review action
A metric signals a question; it does not establish causation. Record an owner, an evidence check and a review date. The illustrative case studies show this sequence with synthetic values rather than promised customer outcomes.
