How did you evaluate a 15% improvement (from the resume about the monitoring dashboard)?

To evaluate a 15% improvement in a monitoring dashboard, key metrics are usually compared before and after implementing changes. For example, if the dashboard shows system response time, the average response time is measured for the period before and after improvements.

Example:

• Average response time before: 200 ms
• Average response time after: 170 ms

Difference: (200 - 170) / 200 * 100% = 15%

Statistical methods such as A/B testing or trend analysis can also be used to ensure that the improvement is genuinely related to the changes and not random fluctuations.
