To audit a Power BI semantic model for performance/design issues, which Tabular Editor tool should you use?

• A. Best Practices Analyzer
• B. Model Health Check
• C. Performance Optimizer
• D. Design Quality Monitor

Answer: (A)

Best Practices Analyzer is the tool in Tabular Editor designed to audit a Power BI semantic model for design and performance issues. It runs a suite of established rules across the model—covering measures, relationships, hierarchies, column properties, and other design decisions—and flags items that can slow queries or lead to unclear or brittle models. By highlighting things like problematic relationships, unnecessary or implicit measures, wide tables, or suboptimal aggregation settings, it gives actionable guidance to improve both performance and maintainability. Other tools may touch on health or performance in narrower ways, but this analyzer provides a broad, targeted review of common best-practice pitfalls in one pass.
