Reliability · Flashcard
What do the DORA “four keys” metrics measure?
- ASoftware delivery and operational performance — how quickly and reliably a team ships changes to production
- BThe raw code quality of a repository — how many style violations and bugs a static analyzer can detect
- CIndividual developer productivity — how many lines of code and commits each engineer produces per sprint
- DInfrastructure spend efficiency — how much a team pays per server and how fully its capacity is utilised
Why this is the answer
The four keys measure a team’s software delivery performance: the speed and stability of getting changes to users. They are not a static code-quality score, which counts style and bug findings. They deliberately avoid per-developer output like lines or commits, which DORA warns against as a productivity proxy. And they do not measure infrastructure cost or utilisation, which is a separate financial concern.
