Data-quality checks before starting a Power BI programme
A polished dashboard cannot compensate for disputed measures, incomplete sources or transformations that nobody owns.
Define decisions and measures
Agree the user question, calculation, time window, denominator, units, exclusions and accountable owner.
Profile sources and transformations
Check completeness, validity, identifiers, unusual changes and undocumented manual adjustments across the information path.
Plan refresh, access and support
Agree currency, failure response, sensitive-data access, service ownership and a controlled reporting slice for initial release.
