Essential QA Metrics to Measure Product Quality


An effective QA strategy always can be measured. It should help measure product quality, team efficiency and must provide critical insights into your software testing process.


In this post we will understand more about how QA metrics can help in measuring product quality and must bring in usage by every quality leader.


The Importance of Measuring QA


QA processes can be full of friction that slows down deployment and eats up valuable resources. Tracking key metrics around the QA process helps identify where your team’s time and budget are being used ineffectively and optimize accordingly.


Equally important is measuring the efficacy of the testing process — bugs that slip through to production are expensive to fix and can negatively impact customer confidence in your product.


Hence its very much important both for Manual and Automation tests to measure QA in right manner.


Finding the Right QA Metrics for Your Team


Because development and QA processes vary greatly from team to team, the measurements that matter can be different depending on the team makeup, tools and software used, customer expectations and more.


As a baseline, the quality metrics your team tracks should be:


1. Measurable

2. Actionable

3. Track able over time

4. Maintained and updated regularly

5. Tied to business goals


With these parameters in mind, there are a few key numbers that every team should consider including in their QA metrics.


These are:


1. Test Coverage

This metric determines the number and spread of tests across the code base. This provides insight into where your resources are being used.


It helps you understand which areas of application under tested and also determine where your test team should spend more efforts.


2. Flaky Tests

Broken and unreliable tests that are not providing useful quality feedback termed Flaky tests. Flaky tests not only waste time and resources, but also reduce overall confidence.


Tests that Pass or fail intermittently fall under flaky tests and must be fixed as early as possible.


3. Time to Test

Amount of time it takes to run and report results for a set of tests. This helps teams understand how to make testing cycles as efficient as possible.


It can be measured how long it takes to run smoke and regression tests after a new build. How long it takes to run new feature tests.


4. Time to Fix

Amount of time between when something breaks and when it is fixed giving insight into QA and Developer communication


It can be measure by checking source of reported issues from internal internal testing and customers. The process that follows while fixing any bug


5. Escaped Defects

The number of defects that reach customers. This is one of most direct measures of QA success.


It can measure from number of defects that reach production, Percentage of affected customers, Impact on affected customers, Product area and Time to fix.


6. Net Promoter Score

Helps in assessing customer satisfaction and product performance.


Overall product performance under different environments along with feedback from customers helps in determining Net Promoter Score of your product.


Apply all the above quality metrics in your project and measure how effective your product quality going to be.
