Top 12 essential metrics for QA process measuring

In the world of development, there is an undying rule that you can't improve what you can't measure. And of course, this rule applies to quality assurance.

In the world of development, there is an undying rule that you can’t improve what you can’t measure. And of course, this rule applies to quality assurance.

​​The arrays of produced software are growing exponentially, which means that the amount of test coverage required to guarantee quality is increasing to the same extent. Which also leads to that kind of causal relationship — more lines of code, more defects. So, in addition, to prepare the QA team for test automation and optimisation, you also need to think about implementing an effective bug reporting tool.

However, even with an effective web-based test case management tool in place, it is necessary to understand what progress metrics in software testing need to be applied in order to get a clearer picture of the efficient efforts of quality assurance. In this article, we will analyse what test metrics and measurements are considered essential, which of them are premier in the agile methodology, and which KPI is necessary to track the performance of the team.

How to understand what ​​Quality Assurance metrics to use

Before you start evaluating your own testing process, you need to determine what specific types of metrics in software testing you might need for this. 

Once the questions are answered you can go further and choose QA testing metrics that can meet your requirements. However, you should remember that metrics are not universal — different businesses need different metrics and measurement in software testing. So, we recommend you learn more about aqua ALM reporting features and explore Report wizard.

QA effectiveness metrics

Absolute Numbers:

Absolute metrics are a great way to get a general idea of how the current testing processes are built. And their presence is recommended for all types of development.

Test Execution and Bug Fixing

Test metrics in software testing showing the correlation between completed tasks from the total number of functions allow the whole team to understand which errors in which modules disrupt the product and should be addressed primarily:

Test Design

Test design coverage evaluates the correlation between test cases and the number of requirements, while test design performance evaluates the number of test cases generated per day. It is done to find out gaps in functionality on the end-user side:

Test Coverage

Test coverage evaluates test effort and gives the idea of what percentage of the application has been already tested.

User Acceptance Testing

This metric is supposed to discover missed issues that might occur due to gaps in the testing strategy:  

Product Exploitation and Support

This metric is used for strategy improvements to boost testing performance. It also evaluates testing effectiveness by showing the number of undiscovered issues that need to be addressed before production deployment: 

Test Economics Metrics

The cost of testing consists of infrastructure, tools and workforce. This metric evaluates how much needs to be spent to finish the project and how much is actually spent:

Test Execution Status

This metric is better to be represented in a chart to display the total executions organised as passed, failed, blocked, incomplete, and unexecuted.

Defects Created vs. Defects Resolved Chart

This metric is supposed to control defect removal processes and understand testing effectiveness metrics.

Overall Metrics

Overall testing metrics measure the effectiveness of your test strategy in general identifying needed improvements:  

Conclusion

The proper use of the metric for software quality is possible to get the desired results from testing. Their presence in modern development processes such as agile helps managers accurately define smaller goals for each sprint. Using benchmarks and KPIs as a navigator, testers understand what result they should get and what numbers they should focus on. In case of deviation from these test efficiency metrics, we can talk about a change in trends. Such deviation can indicate a critical mistake that could jeopardise the success of the project. In this way, managers can pre-check and refocus their team without waiting for the end and thus prevent additional development costs. 

Given all the above, we can unequivocally say that quality metrics in software testing in the development process can improve its quality and prevent unnecessary risks.

What are quality assurance metrics?

Quality assurance metrics are indicators used to see whether the QA team is keeping up. You can track both how well the team is meeting their targets and how those targets stack up to industry standards.

How do you measure QA performance?

You measure QA performance by QA metrics, such as Defect Detection Ratio, Test Coverage, and Rework Effort Ratio.

What are the types of QA metrics?

QA metrics can roughly be split into test design, test execution, defect detection, and overall outcome types.
