BenefitsEmpowered Testers Testing at Any Level No Waiting for UI Simplified Troubleshooting Persisted Test Cases Test Case Reusability
Test Case Repeatability Audit Log Automated Reporting Earlier Feedback & Acceptance Faster Tests

– More friction can smooth those edges over time – Remember, iron sharpens iron
New awareness in retro New types of questions, more dialog in grooming and planning sessions Chunks of work start getting smaller Demos have WORKING code!
