NEKLO’s Insights on Key Metrics for QA Teams

When outsourcing software development, you want to get the whole picture of the project in progress in another part of the globe. How can you check software quality remotely? One efficient way is to include QA metrics in your service provider reports. 

QA metrics help ensure better quality of the product, make development processes more effective and aligned with your business goals. Our Senior QA engineer, Oleg Khadyka, discusses the importance of collecting and analyzing QA metrics, along with interpreting results accurately. 

Meet Oleg - NEKLO's Senior QA Engineer with nearly 9 years of experience in QA, skilled at testing embedded, web, backend, and IoT systems.

What Are QA Metrics?

A metric is an indicator used to evaluate a process, activity, or final product. It can improve product’s quality and show the effectiveness of QA team work, helping optimize quality assurance processes. However, collecting mere numbers can be misleading and a very pointless exercise, if you do it without the particular goal in mind. 

There are dozens of QA metrics you can collect. Let’s discuss some and see how you can use them thoughtfully. 

  1. Escaped Defects: despite the QA team preventing most bugs, there is a chance that some bugs will leak to production, especially in demanding release timelines. The metric not only shows QA team process efficiency but also works as a health check for all development processes.
  2. Number of Identified Bugs: self-explanatory. Each bug found is labeled by priority and severity, indicating what impact it has on software and how quickly it needs to be fixed.
  3. Test Case Effectiveness: reflects how many cases written and executed by your QA team identified bugs per development cycle.
  4. Defect Density: indicates how many defects software has per requirement. This indicator can tell whether one requirement is riskier than another and adjust the feature or decide against its release. It can uncover the issues with the requirement itself.
  5. Average Time to Test a Bug Fix: this software QA metric helps identify if additional testing resources are needed, maintain product quality, and evaluate development cycle efficiency.

Why Track Software Quality Metrics

Software QA metrics bring you a clear vision on product quality, QA team performance, and can help tune QA processes according to the data received. Other aspects include the following activities:

Monitoring Project’s Progress

QA metrics are essential for timely and quality features delivery. They provide insights about project advancements, help track milestones, estimate software’s stability and check whether the project is going at a sustainable pace.

Improving Project Management

QA metrics give the basis for the project management improvement. Measurements like test coverage, requirement traceability, and defect density, helps to better prioritize tasks, allocate resources, balance workloads, and optimize testing efforts. 

Getting Objective View on Quality

Implementation of quality metrics allows to measure software quality aspects such as performance, security, and reliability. You can make an adjective assessment relying on data and identify issues and improvements and adjust the QA process.

Identifying and Solve Project Issues

Collecting QA metrics allows to quickly identify bottlenecks and testing gaps. Defect density, for example, helps to identify features with a high defect rate, which may require refactoring or additional resources.

Ensuring Software Quality

By conducting various types of testing, the QA team ensures that the product meets the client's requirements: all features, integrations and processes work correctly. In this case, QA metrics reflect that the software works as it was intended. 

FAQ

Now, let’s uncover the main aspects you might be the most curious about.

How to Define Metrics I Need to Collect?

Surely, you don’t need to collect all QA metrics. There may be some irrelevant information for the team or project. You should collect measurements based on the goal they serve. Do you want to identify bottlenecks in the QA process because you feel there are some? Or adjust team size for better resource allocation? Or evaluate product stability?

When choosing metrics you want to include in the reports, proceed from your business goals and development methodology. Use metrics that show business results and customer satisfaction, as well as those that show the team’s performance. Remember, that choosing too many metrics may not give you clear results, and there is no single approach.

What to Consider Before Collecting QA Metrics?

You should understand the purpose of collecting QA metrics in Agile: know what kind of metrics you need and what result you want to achieve. Align metrics with business objectives to avoid wasting efforts and resources.

How to Interpret the Results Accurately?

When analyzing metrics, stay objective, consider all data influencing the results, and interpret metrics in the context of the specific project's tasks and needs.

How to Increase the Efficiency of Collecting QA Metrics?

Alienating the QA team from the software development process decreases efficiency in collecting QA metrics. Quality assurance should be integrated throughout the entire development process, with QA involvement at every stage.

Final Thoughts

Gathering QA metrics includes foresight and planning, setting goals, and forecasting results. The key point here is that while choosing metrics you want to include in the test result report, rely on your goals, e.g., how this metric can solve a specific problem or task. Choosing random points from top-30 QA metrics lists might be ineffective. The measurements must align with business goals and be tailored to particular teams and products. 

During the webinar, QA engineers enthusiastically shared experiences, asked questions, and sparked a lively discussion with the speaker. Inspired by the event’s energy, the NEKLO team decided to plan another webinar on related topics and set up regular meetups to chat about the latest software development.
