Measurable metrics are the most effective way to assess the success of DevOps services. 

1. Deployment Frequency

Calculates the frequency of updates or new features. Increased frequency denotes increased efficiency and agility.

2. Lead Time for Changes

Monitors how long it takes for a change to go from development to implementation under DevOps implementation services. A more efficient development process is reflected in shorter lead times.

3. Change Failure Rate

Keeps track of the proportion of deployments that fail or need to be rolled back. Greater stability and dependability are indicated by a low failure rate.

4. Mean Time to Recover (MTTR)

Calculates how long it takes to bounce back from an event or failure. Business continuity is ensured and downtime is reduced with a shorter MTTR.

5. Cycle Time

Keeps track of how long it takes to complete development tasks from beginning to end. Workflows that are more efficient have shorter cycle times.

6. Customer Satisfaction

Although they are not technical metrics, Net Promoter Scores (NPS) and customer satisfaction surveys offer important information on how DevOps services will affects user experience.
