Dora metrics is the abbreviated form of DevOps Research and Assessment. The Dora metrics were developed after intensive studies over the period of six years and ultimately concluded with a set of four key metrics that were termed as very crucial for software development.

Key elements of Dora metrics
These four Dora metrics help the software developers to finish their work abiding by the company goals.
It is the number of times the dose gets deployed during production. It is measured as per the number of times used in a day or in a week. The increase in deployment frequency means that the efficiency of the team and the way it is working is in process. The deployment frequency can be increased when the team has work in the pipeline and the order are delivered meeting the goals.
Mean lead time for changes
It is the time taken to accept working n the code till the date the code is delivered. Some development companies measure it after accepting the code, while others commit to it before accepting the order. There are organizations that roll the meantime into a metric called cycle time.
A lower mean time means that your workers are able to deliver on time and are good with coding. While a longer mean time indicated that the team might need more time of delivering work.
Mean time to recovery (MTTR)
It is often known as the mean time to store. It is the time taken by a team to rectify a failure in the system. Failure in the syren indicates bugs in the system.
A lower mean time indicated that a team takes less time in recovering from the failure, while a longer mean time indicated that the team took a long time to recover from the bug. A shorter mean time is always good because the sooner the problem will be fixed, the sooner the team can resume the work and deliver it.
Change failure rate
It is the failure that occurs when a code changes. It is an important metric as the time that is spent fixing the bug, is the time not spent in delivering new work. You should always aim to lower the problem so that you can deliver good quality to your customers.
