When it comes to software quality, there’s no single way to assess process effectiveness. The market has already established reference models that help in this journey, such as TMMi (Test Maturity Model Integration). This model provides a framework for diagnosing a company’s testing maturity stage, offering security, comparability, and guidance for improvement.
The role of QA (Quality Assurance) goes far beyond system compliance. It connects the entire quality process of the product, ensuring predictability, consistency, and reliability in deliveries. Understanding your company’s QA maturity level is essential to support strategic decisions, reduce risks and costs, increase customer satisfaction, encourage continuous improvement, and strengthen market competitiveness.
The following are the main QA maturity levels:
Level 1 – Reactive
Testing is performed manually, focusing on finding defects (an activity more aligned with QC – Quality Control). There is no clear definition of testing processes or strategies. This scenario generates high rework, low reliability, and a high risk of bugs in production.
Level 2 – Post-Failure Corrections
Testing is more reactive, with fixes triggered only after production failures. While this represents an improvement over the previous level, it still lacks predictability, low efficiency, and limited QA involvement in the quality process.
Level 3 – Predictive
At this stage, testing begins to be planned and aligned with the QA culture. The testing strategy is defined from the early stages of development, using partial regression testing automation. Defects are identified earlier, which avoids rework, reduces costs, and increases confidence in deliveries.
Level 4 – Integrated Automation
The company invests heavily in automation and continuous integration through CI/CD (Continuous Integration, Continuous Delivery) pipelines. Every change to the system is automatically validated, ensuring broad coverage and greater reliability. QA is no longer just an executor and assumes a strategic role in maintaining quality throughout the development cycle.
Level 5 – Culture of prevention
The focus is on continuous prevention, fully aligned with the DevOps culture. There’s in-production monitoring and real-time feedback. The developed code already includes unit testing and static analysis, ensuring high quality from the start. Regression risk is minimized due to the scalability and comprehensiveness of automated testing.
Final reflection
Understanding these maturity levels is the first step toward structuring a solid quality strategy. Models like TMMi provide the necessary framework to guide this process.
