Software quality metrics help measure whether the product is stable, reliable and fast. For beginners, the challenge is to choose simple metrics and understand how to apply them in everyday life. The objective is not to measure everything, but to measure what really matters.
This guide presents basic use cases and metrics for those just starting out.
Basic metrics
- Crash rate: indicates production failures.
