Typical orphaned content found

Most Power BI environments have at least three of these five issues

Measure logic errors — DAX measures that look right but produce incorrect totals at different grain levels. SUMX used where SUM would work. CALCULATE filter context misunderstood. These are invisible until someone drills through and the number changes unexpectedly.

Slow DirectQuery reports — model on DirectQuery when data volume does not justify it, or DirectQuery without query reduction settings, sending hundreds of queries per visual render. End users see 8+ second load times and blame 'Power BI' rather than the model configuration.

Relationship chaos — many-to-many relationships everywhere because someone did not normalise the model. Cross-filter direction set to Both across the entire model, causing circular ambiguity and incorrect filter propagation.

No row-level security — everyone in the company can see everyone else's regional data, never configured because the original builder 'didn't need it for the pilot.' Common in environments built by a one-off contractor who no longer works with the company.

Orphaned reports and datasets — 40-60% of workspaces we audit have reports that nobody has opened in 90+ days consuming gateway connections and refresh slots. This is a licence waste issue that the audit surfaces immediately.

Why choose Lets Viz for your Power BI audit

A fix list, not a judgement

We have audited environments built by one-person IT departments, ex-Excel users, and well-meaning contractors. The report is actionable, not critical.

DAX Studio profiling, not guesswork

We run Server Timings on your 10 slowest measures, inspect Storage Engine query plans, and identify Formula Engine overhead. Every slow measure in the report includes the specific DAX pattern causing the bottleneck.

Full environment view, not just report design

We look at the workspace structure, dataset sharing, sensitivity labels, service principal configuration, and refresh history — not just whether the visuals look nice.

Prioritised by impact and effort

Every finding is scored High / Medium / Low for impact and Quick win / Sprint / Full rebuild for effort. You get a ranked list — not a wall of recommendations with no guidance on what to do first.

No Global Admin access required

We need Viewer access to the workspaces being audited and Read access to datasets to run DAX Studio queries. We do not require Global Admin or Power Platform Admin roles. NDA signed before access is granted.
