Data Modeling & DAX Optimization

Fix slow reports, inconsistent calculations and complex models. Build Power BI and Microsoft Fabric semantic models that your teams can trust and maintain.

Slow visuals, unexpected totals and fragile calculations often need more than a rewritten DAX measure. We review your model structure, relationships and calculation logic to identify the causes behind performance and accuracy issues.

We redesign the areas that need improvement, optimise priority measures and validate the results against agreed business rules. Your team receives a clearer model, documented calculations and a comparison of performance before and after the changes.

What We Work On

We focus on three areas: model structure, DAX performance and consistent business calculations.

Semantic Model Design

We review fact and dimension tables, relationships and filter behaviour. We restructure the model where needed to simplify analysis and support maintainable calculations.

DAX Troubleshooting & Performance

We investigate slow measures, unexpected totals and filter context issues. We optimise priority calculations and compare query performance before and after each change.

KPI Definitions & Validation

We translate agreed business rules into reusable measures. We test calculations across reporting scenarios and document how each KPI should behave.

What You Receive

Receive clear findings, targeted improvements and practical documentation for your team.

A review of your tables, relationships, measures and key performance bottlenecks.

Recommended changes ranked by business impact, implementation effort and dependencies.

Improvements within the agreed scope, supported by performance comparisons and calculation checks.

Documented business logic, modelling decisions and guidance for maintaining the solution.

When to Contact Us

Contact us when performance issues or calculation complexity make your reports difficult to trust or maintain.

Slow Reports

Visuals take too long to load or respond to filters.

Growing Model Complexity

New tables and reporting requirements make your model harder to maintain.

Complex DAX

Measures are difficult to understand, troubleshoot or safely modify.

Unexpected Results

Totals or KPIs change in ways your team cannot explain.

We assess your model, optimise the priority areas and validate the results with your team.

Assess

Review model structure, calculation logic and query performance. Agree on business rules and validation scenarios.

Optimise

Improve priority relationships and DAX measures, measuring the effect of each change.

Validate & Handover

Check calculation accuracy, compare performance and document the changes for your team.
