Power BI starter: measures that match the question
Name Power BI measures after the question, write DAX that respects filter context, and test before the card goes live. Columns are raw material; measures are answers.
Peeking, guardrails, and stopping rules
Stop peeking at interim p-values as final decisions. Use fixed horizons or sequential plans, guardrail metrics, and a written stopping rule before launch.
Catalogs and where is the truth?
Build a one-page truth map and a minimum catalog card for each critical dataset. Certification is a promise with an owner, not a sticker on a dashboard.
Multimodal AI for charts and screenshots
Use multimodal AI on charts with visible-only asks and uncertainty labels. Verify dips and drivers in the source data before you paste the model’s story into Slack.
Share with a team without creating chaos
Share Custom GPTs with one owner, one live version, and clear edit rights. Kill ghost copies before the team trusts disagreeing answers.
