Why does a dashboard show numbers nobody trusts?
A dashboard loses authority the moment a manager must open a spreadsheet to check its headline number.

Start with one disputed measure
Ask what it means, which records feed it, when they refresh and who can correct a source entry. Compare a handful of cases with the people who rely on the number. This often reveals a timing or definition conflict rather than a software defect.
Do not average conflicting figures into a single reassuring number. Some differences represent distinct business events.
Earn trust through traceability
Show the measure's definition and update time. Make it possible to investigate an unusual figure and to repair a source error. Agree who signs off a change to the calculation.
Once the number is dependable, visual design can help people see the decision it supports. It cannot make an undefined measure true.
The dashboard counts an order when it is accepted; the sales team counts it when the customer signs. Both call the figure “new orders”.
Give the measures different names and document their uses. Then test a few real orders through both calculations before redesigning the chart.
