Numbers you can defend, not just display

Reconcile your data, end to end

The costliest failure in analytics is the silent one: a dashboard that keeps rendering a plausible but wrong figure. Wiiisdom compares the values displayed in your Tableau content against the underlying source of truth, applies statistical validations and value checks, and surfaces discrepancies before anyone acts on them.

Certify accuracy automatically

Accuracy testing is the engine behind Continuous Certification. When an asset passes, it is certified automatically and carries a dynamic trust stamp your users can read. When it fails, certification is revoked and the right people are alerted. No other Tableau testing tool closes that loop.

Catch drift, not just breakage

A broken dashboard gets reported within the hour. A dashboard that renders perfectly with a subtly wrong number gets acted on. Continuous reconciliation is what separates the two, because it compares against the source every run rather than trusting a validation performed at go-live.

Make Tableau AI-ready New

AI answers only as well as the analytics it runs on. Tableau agents, Pulse, and external LLMs consume your published data sources to generate answers. Certifying the accuracy of those sources ensures AI-generated insights start from validated ground instead of amplifying an error at machine speed.

No code. Continuous. Open to AI.

Data reconciliation

Compare dashboard and data source values against the underlying source of truth, at scale.

Business rule validation

Validate the rules your dashboards are supposed to obey — expected row counts, value ranges and thresholds, mandatory fields, calculations and aggregations — and fail the check the moment a figure falls outside them.

AI-generated validation pipelines New

Describe the accuracy test you need in plain language and let AI build the pipeline. Every step stays editable.

Open to AI via Wiiisdom MCP New

External LLMs and the Wiiisdom conversational agent can check an asset's accuracy status or trigger a validation through the Wiiisdom MCP Server.

Proactive alerting

Notify BI teams in Slack, Teams, or your ticketing system the moment a validation fails.

Audit trails

Capture every test, execution, and result with full traceability for internal and regulatory requirements.

From spot checks to continuous reconciliation.

Checking figures against the source by hand is periodic, partial, and stops the day the project ships. Wiiisdom reconciles every business-critical asset continuously, and turns the result into a trust signal users can read without asking anyone.

Manual accuracy checks
  • Someone eyeballs a handful of figures against the source, when there is time
  • Reconciliation happens at go-live, then effectively never again
  • A plausible but wrong number renders perfectly and raises no flag
  • The error surfaces when a business user disputes it, after the consumption
  • Trust is asserted in a meeting, not evidenced
With Wiiisdom
  • Every business-critical asset reconciled against the source on a schedule
  • Statistical validations and business rules applied identically, every run
  • Silent discrepancies caught before a user ever encounters them
  • Certification revoked automatically the moment values drift
  • Timestamped evidence of every check, ready before the auditor asks

Accuracy is one of seven BI testing dimensions.

Testing is the foundation. It powers the three capabilities of the Wiiisdom platform.
