What threshold value is considered 'Unacceptable' in Apdex?

1. 0.9

2. 0.8

3. 0.7

4. 0.5

The correct answer is: 0.5

In Apdex scoring, a threshold value of 0.5 signifies 'Unacceptable' performance levels for user satisfaction. Apdex is a performance metric designed to measure user satisfaction based on response times. It uses a scoring system where different thresholds indicate varying levels of user experience. When the Apdex score falls below 0.5, it indicates that users are experiencing problems with the application, leading to dissatisfaction, frustration, or an inability to use the application effectively. This score reflects that more than 50% of the user interactions are not meeting the acceptable performance criteria, which highlights a significant issue that needs addressing. The other threshold values indicate different levels of user satisfaction; for example, scores of 0.7 and above are considered acceptable and indicate that users are generally content with the application performance. Therefore, 0.5 serves as a critical cutoff point signifying that remedial actions are necessary to improve user experience.
