Measuring DevOps: Key ‘Metrics’ and ‘KPIs’ That Drive Success!
DevOps, the word that needs no introduction in a software environment!
Making its entry as a process to streamline software delivery, DevOps emerged to become a whole and sole for most organizations.
Not just impacting the software delivery, DevOps best practices brought about an all-round cultural transformation filling the void among teams.
All these advantages with DevOps don’t so come easily and the secret lies in the understanding of a few metrics and Key Performance Indicators (KPIs).
Here, we bring to you the ‘Key DevOps Metrics and KPIs’ that stand crucial to successful DevOps journey:
1) Time and Frequency of Deployment
A single/bulky deployment for a longer period is the old concept. In the DevOps world, more deployments get you more releases and improves your business interaction with end-user. Tracking the frequency of deployments keeps you on track and helps you plan smaller deployments that ultimately reflect in improved test and release cycles.
This will also cut down deployment time, which would often result in a lot of investigation time.
2) Change Volume
Code is the deciding factor here. Change Volume refers to the lines of code you push to production per deployment. Measuring this is crucial to measuring the success of deployment in terms of value, time and frequency.
3) Meantime To Failure
This is also referred to as the failed deployment rate and also related to change volume. Increasing meantime to failure along with the low change volume causes process dysfunction, leading to delay in the workflow.
4) Meantime to Detection and Recovery
Meantime to Recovery (MTTR) is the time required to recover from a failed instance. This defines your organizational ability to face and address failures. This is one of the most popular DevOps metrics. Meanwhile, Mean time to Detection (MTTD) refers to the time you take to identify an issue, which requires application monitoring to identify at an early stage.
5) Change Failure Rate
Change failure rate is something that explains the extent of release failure caused by unexpected outages or other failures. A low change failure rate means faster and timely deployments. Whereas, the high side of it means poor application performance impacting end-user satisfaction.
6) Lead Time
This is crucial if the end goal is ‘faster shipping’. This is measured as a time that the change process takes to happen, from start to the deployment phase. This helps you make estimates about the overall time a specific task will take to get into production.
7) Early Detection of Failure
This is as important as executing the process. Any unexpected failure may stall the process. So, early detection of failure helps you find appropriate solutions without any delays and recover faster to get on track. It also helps you assess if the implemented response measures are enough.
8) Customer Feedback
More product feedbacks or alerts from your customer support team means more gaps in your business at the customer end. The worst thing that a business never expects is bad feedback from the end-user. Given this factor, customer feedback (positive or negative) makes one of the strongest metrics for DevOps success.
9) Automated Test Cases
Automated test cases have to be used to the maximum to derive better performance results in DevOps journey. Extensive usage of unit and functional testing naturally boosts the workflow velocity. Keep a close watch on code changes and their impact on test cases. Ensure automated tests run perfectly!
10) Service Level Agreements (SLAs)
Ensure to be compliant to your SLAs. Any disagreement with SLAs cause issues at a later stage hampering the workflow. It’s important to operate in line with your SLAs. In the absence of SLAs, make sure to stand in line with the set application requirements.
This basically refers to the presence of service during the downtime. It is usually in two ways as partial (read-only) and complete (read and write) availability. Less downtime results in more availability. However, 100 percent availability is unrealistic as planned downtimes would be required to conduct scheduled maintenance activity.
12) Unplanned Work Rate
This is another important DevOps metric that speaks the effective utilization of efforts. This calculates tracks the time spent on an unplanned work to that spent on a planned one. The unplanned work rate is often compared with the rework rate, which is linked to the efforts caused in addressing feedback.
13) Defect Volume and Escape Rate
This rate examines how often the defects are identified and uncovered at the pre-production phase compared to production phase. The defect escape rate reflects the core principle that defects are natural part of a software development cycle and should be identified early in the process.
14) Application Performance
Best practice is to check the application performance well before its deployment. There are specific tools that can help you trace performance issues, hidden errors and other gaps within an application. This monitoring of application performance has to happen even after deployment.
15) Process Cycle Time
This KPI measures the complete time taken from the stage of ideation to ending with user feedback. This metric presents a broader view of application deployment. Shorter cycles are highly recommended but not at the cost of defects.

Steps to Implementing DevOps ‘KPIs’
While we have seen a list of key metrics and KPIs, it’s equally important to know the way they are implemented in a DevOps process.
The implementation of DevOps KPIs is built on five steps:
Identify the set of KPIs to be tracked for your organization
Prepare dashboards to view or list KPI results
See how successful these KPIs are in meeting business goals
Plan strategies for performance improvement in respective areas
Cross-check if KPIs meet the desired objectives and make changes, if necessary
These five steps help you in effective implementation of the identified KPIs and metrics to drive your DevOps success.
