Most Power BI dashboards fail for the same handful of reasons. After building and reviewing dashboards for finance and operations teams across the UAE, the same mistakes come up again and again — and all of them are fixable. Here are ten of the most common, and how to put them right.
1. Building visuals before the model
The biggest mistake is starting with charts instead of a data model. Visuals built on raw queries look fast but break with every change. Fix: design a clean star-schema model first, then build reports on top.
2. Cramming everything onto one page
A dashboard with forty visuals answers nothing clearly. Fix: lead with one headline number per view and let users drill for detail.
3. No clear question
Dashboards built without a decision in mind become data dumps. Fix: define the top three questions the dashboard must answer before you build.
4. Numbers without comparison
A revenue figure alone is meaningless. Fix: always pair a number with a comparison — target, prior period or budget — so viewers know if it is good or bad.
5. Poor performance
Slow reports lose users. Common causes are bloated models, too many calculated columns and inefficient DAX. Fix: reduce the model, prefer measures over calculated columns, and optimise the heavy DAX.
6. Inconsistent formatting
Different colours, fonts and number formats on every page erode trust. Fix: use a theme and consistent formatting so the report looks like one product.
7. No row-level security
Everyone seeing everyone’s data is a governance risk, especially for finance. Fix: implement row-level security so people see only what they should.
8. Misleading visuals
Truncated axes, 3-D pie charts and rainbow colour schemes distort the message. Fix: use simple, honest visuals — bars and lines beat novelty charts almost every time.
9. Manual refresh
A dashboard someone has to refresh by hand is a dashboard that goes stale. Fix: set up scheduled refresh or a gateway so data is always current.
10. No handover or documentation
When only one person understands the report, it dies when they leave. Fix: document the model and train the team so the dashboard outlives its builder.
The common thread
Notice how many of these trace back to one root cause: skipping the data model. Get the foundation right and most of these problems never appear.
