Power BI Diagnostics
When your Power BI reports exist —
but nobody trusts them.
A structured diagnostic review of your Power BI environment. Models, measures, definitions, performance and usability — examined properly, not assumed.
Common symptoms
- Two reports show different numbers for the same metric — and nobody knows which is correct
- Dashboards exist, but leadership still asks for data in Excel
- Reports take minutes to load or fail silently on refresh
- DAX logic is undocumented, untested, or built by someone who has since left
- No governance — anyone can publish, nobody owns definitions
- Measures were built quickly for a demo and never reviewed
What the diagnostic covers
Model Structure
Table relationships, cardinality, star schema compliance. Identifying where the model creates ambiguity or incorrect aggregations.
DAX & Measure Logic
Validation of measures, calculated columns and filters. Checking for common anti-patterns, context transition issues and logic errors.
Performance
Refresh times, query performance, storage mode analysis. Identifying what's slow and why — not just that it's slow.
Governance & Definitions
Metric definitions, naming conventions, RLS implementation, workspace structure. The operational foundations that determine whether reports survive scrutiny.
How it works
What you walk away with
- A clear picture of what's broken and why
- Prioritised remediation plan — not a vague list of suggestions
- Validated measures and model structure
- Performance baseline and improvement targets
- Reports your leadership team can defend in meetings
Good fit if…
You have Power BI reports that exist but aren't trusted, are slow, give conflicting numbers, or were built by someone who is no longer around. You need an independent expert to tell you what's actually wrong — honestly.
Not a fit if…
You need a training course, want a pretty dashboard redesign without structural changes, or are looking for ongoing managed services. I diagnose and fix — I don't babysit.
