DevOps transformation goals can be defined as:
- Heightened Release Agility
- Improved Software Quality
Delivering Better Software Faster
Therefore measurable DevOps success criteria would be:
- Being able to release versions faster and more often
- Having less defects and failures
We all know that improvement doesn't happen overnight, but instead is an iterative, continuous process. We want to be able to measure our improvement by applying a scientific step sequence of hypothesis->test->analysis->proceed on the outcome->...
In order to measure DevOps flow improvement we need to have metrics for 2 categories:
- Velocity (time it takes to complete each step in the release/delivery cycle, number of releases per time period.)
- Quality (rate of defects per change, etc)
Here are the 12 core KPIs we've come up with. Also known as the DevOps Flow Metrics.
6 for Velocity and 6 for Quality:
MLT (Mean Lead Time)
how long does it take for a bit of code to get built, tested and deployed.
DCR (Daily Change Rate)
number of changes getting committed to mainline and tested per day.
MTTE (Mean Time To Environment)
how much time it takes developers/testers to bring up a testing environment for verifying each delivered change. "
MTTD (Mean Time to Detect)
how much time passes since the original commit of code until the bug it introduces gets detected.
MTTR (Mean Time To Resolve)
how much time it takes to resolve an issue after it’s detected
MTTA (MeanTime To Approve)
how much time it takes to approve and verify a release. (Measured from the moment all release content has been delivered and until the release has passed all the defined test and verification cycles)
BFR (Build Failure Rate)
% of failed builds
DFR (Deployment Failure Rate)
% of failed deployments
IRFR (Infrastructure-Related Failure Rate)
% of build/deployment failures related to infrastructure issues
RWR (Rework Rate)
% of tickets being reopened
ADR (Automated Detection Rate)
% of defects being detected by automated testing cycles
UWR (Unplanned Work Rate)
% of unplanned issues
