Ideas to improve this metric Thoroughly test code before deployment Use error tracking tools Handle exceptions properly in the code Keep third-party scripts updated Perform regular code reviews 5. User Satisfaction (Apdex) Score A metric that measures user satisfaction based on response times, calculated as the ratio of satisfactory response times to total response times
What good looks like for this metric: 0.8 or higher
Ideas to improve this metric Monitor and analyse performance regularly Focus on optimising high-traffic pages Implement user feedback mechanisms Ensure responsive design principles are followed Prioritise backend performance improvement
