Performance Reporting, Defect Triage and Tuning Recommendations Basics Overview

The Performance Reporting, Defect Triage and Tuning Recommendations Training Course is designed to provide participants with practical knowledge and skills in analyzing performance test results, preparing meaningful performance reports, conducting defect triage, and recommending effective tuning actions.

This course focuses on the post-execution phase of performance testing, where teams interpret test results, identify bottlenecks, classify performance defects, communicate findings, and recommend improvements to application, database, infrastructure, and network teams. Participants will learn how to transform raw performance test data into clear reports, actionable insights, and prioritized tuning recommendations.
