Power BI Health Check Service: A Done-For-You Audit

What exactly is a Power BI audit?

It's a structured, senior-led review of everything between your source data and the executive's screen: the semantic model, the DAX, the refresh pipeline, the security rules, the report pages, and the tenant around them. It ends in a document, not a bill for a rebuild. You decide what to fix and when.

The word "audit" scares people because it sounds like a compliance exercise. It isn't. Think of it as a second opinion from someone who has seen a few hundred Power BI estates and can tell within an hour whether your problem is a modelling problem, a DAX problem, or a plumbing problem — because those three have wildly different price tags and fixing the wrong one is how teams burn a quarter. If you already know your problem is acute and you want hands-on debugging rather than a report, our Power BI troubleshooting consultant service is the faster route.

What do you actually review?

Six areas, every time: the data model and star schema, the DAX measures, refresh and gateway reliability, row-level security, report and visual performance, and workspace governance plus licensing fit. Each area produces findings with a severity and an effort estimate, so the report is a plan rather than a list of complaints.

Data model and star schema. We check whether you have a proper star — conformed dimensions, a single marked date table, one direction of filter flow — or the snowflake-and-spaghetti hybrid that grows when models are extended under deadline. We look at cardinality, calculated columns that should be Power Query steps, unnecessary columns inflating the model, and relationships set to both directions "because it made the visual work." This is where most performance and most tie-out failures originate, and it's the same discipline covered on our Power BI data modeling and DAX service page.

DAX measures. We read the measures, not just run them. Common findings: filter context clobbered by ALL() where REMOVEFILTERS() on one column was meant; iterators over millions of rows where a simple aggregation would do; time-intelligence built by hand on an unmarked date table; measures duplicated eight times with tiny variations because nobody could find the original. We flag the ones that are wrong and, separately, the ones that are merely slow.

Refresh and gateway reliability. We pull the refresh history, look at the failure pattern, and separate the real causes: expired or personal-account gateway credentials, source timeouts, memory ceilings on a Pro workspace, incremental refresh that was never configured so a five-year fact table reloads in full every night. Microsoft documents the applicable ceilings and behaviour in its data refresh reference (opens in new tab), and we assess your setup against them rather than guessing.

Row-level security. The finding nobody wants and everybody needs: whether the RLS roles actually restrict what they claim to. We test roles as the user, look for the classic dimension that isn't filtered by the security table, and check whether "View as" was ever run before the report went live. A silent RLS leak is the single most expensive thing we find.

Report and visual performance. Page-level analysis with Performance Analyzer: which visuals are slow, whether the cost is DAX query time or visual rendering, how many visuals are competing on one page, and whether custom visuals are dragging the whole thing down. If you want the DIY version of this specific piece, we wrote up how to fix slow Power BI reports.

Workspace governance and licensing fit. An inventory of workspaces, datasets, reports, owners, and usage — what's live, what's abandoned, what's duplicated. Then the honest licensing conversation: whether you're paying for Premium capacity you don't use, or squeezing a Premium workload into Pro and paying for it in failed refreshes instead.

What symptoms map to what root causes?

Every audit starts with symptoms, because that's what you can see. The table below shows the paths we most often trace from a visible complaint back to its real cause and the fix that follows — useful for orienting yourself before we look, though the actual finding depends entirely on your estate.

What do you actually hand over?

A written findings report and a walkthrough call. The report lists every finding with a severity (critical, high, medium, low), the evidence behind it, the recommended fix, and an effort estimate in hours. Critical items — RLS leaks, wrong numbers — sit at the top. It's your document; nothing is locked to us.

Concretely, the report contains an executive summary you can forward without editing; an inventory of the workspaces, datasets, and reports in scope; the six review areas each with their findings; a prioritized remediation plan where every line has a severity and an hours estimate; and a "quick wins" section listing what can be fixed in under two hours each. The walkthrough call is 45–60 minutes with the engineer who did the work — not an account manager reading slides — so you can argue with the findings and get straight answers. Afterwards you can execute the plan in-house, hand it to your own contractor, or ask us to burn the remaining Flex hours doing it. All three are fine, and we don't make the third one a condition of the first.

How much does a health check cost?

We don't sell a fixed-price audit, because estates aren't fixed-size. You buy prepaid Flex hours — Starter 20h at $125/hr ($2,500), Growth 40h at $115/hr ($4,600), Power 80h at $100/hr ($8,000) — and the audit draws from that block. A typical health check fits comfortably inside a Starter block.

That matters more than it sounds. A competitor's flat-fee audit has to price in the worst case, and the hours you don't use vanish. With Flex, the hours the audit doesn't consume stay banked — and they never expire — so you can spend them on the fixes the audit just prioritized, or on anything else Power BI-shaped later. We send a scope estimate before we start and deduct hours only for work you've approved. Full detail on the model is on how our prepaid Flex hours work, and if you want an ongoing senior relationship rather than a one-off review, that's Power BI consulting.

Who is this for, and who is it not for?

It's for teams with an existing Power BI estate that's slow, untrusted, unreliable, sprawling, inherited, or about to be migrated. It's not for teams starting from a blank page — there's nothing to audit yet — and it's not for anyone who already knows the fix and just wants hands on keyboard.

The best-fit callers are a controller who can't reconcile the dashboard to the close, an IT lead who inherited a tenant when the BI analyst resigned, an operations director whose refresh fails twice a week (there's a whole guide on the Power BI scheduled refresh failed error if you want to triage it yourself first), and a CIO deciding whether the current estate is worth carrying into Fabric. Increasingly it's also a BI lead who has been asked to switch on Copilot and wants to know what the models would say before anyone starts asking them questions — that readiness work is set out on our Power BI Copilot consultant page, and it goes much better after an audit than before one. If you're none of those and you simply want a competent pair of hands on a known problem, skip the audit and go straight to booking hours — we'll tell you honestly which one you need.

Would you rather do it yourself?

Then take our checklist and go. We publish the same review structure we use internally, free, with no gate: the Power BI health check checklist. If you have an analyst with the time and the appetite, working through it is genuinely worthwhile and you don't need us.

The reason people hire it out anyway is rarely the checklist — it's the judgement. Knowing that a bidirectional relationship is a smell is easy; knowing whether this bidirectional relationship is the reason this report is slow, or a harmless artefact, is the part that takes twenty years. Same for licensing: anybody can read the Pro-versus-Premium feature matrix, but sizing your actual workload against it without over-buying is a different skill. If you'd rather buy the judgement than the hours, that's what this page sells.
