In which phase is quality assurance primarily focused?

Quality assurance plays a crucial role throughout the software development lifecycle, but it is particularly emphasized during the implementation phase. During this phase, the actual coding takes place, and it is essential to ensure that the developed software meets the defined quality standards. Quality assurance activities in this phase include testing the functionality, performance, and security of the software. This involves executing various types of testing, such as unit testing, integration testing, and system testing, to identify and rectify any defects before the product is deployed.

Quality assurance ensures that the software product adheres to both internal standards and external regulations, ultimately striving to enhance customer satisfaction and trust. Although quality assurance practices are also relevant in planning, analysis, and design phases, the implementation phase is where the tangible outputs are tested for compliance with the initial requirements and design specifications. This comprehensive focus on quality during implementation helps mitigate risks and ensures a robust final product.
