Quality Assurance, conversely, is oriented towards the processes that create the software. It's about setting up a systematic, quality-focused approach to development, ensuring that every step from design to deployment enhances the product's quality.
• Activities: The activities involved in software testing are direct and hands-on, involving the execution of the software in various scenarios to identify any issues. Quality Assurance, on the other hand, involves more indirect activities such as the establishment of standards, processes, and procedures that aim to prevent errors before the software reaches the testing phase.
• Goal: The primary goal of software testing is to ensure that the software product meets all specified requirements and functions correctly in all anticipated scenarios. Quality Assurance aims at a broader target: ensuring that the entire process of software development is efficient, effective, and capable of producing high-quality software consistently.
• Outcome: The immediate outcome of software testing is a software product that has been verified to meet quality standards and is free of known defects. The outcome of Quality Assurance is a robust and reliable process that consistently yields high-quality software products, with a reduced need for extensive testing due to fewer defects being present at the testing stage.

By understanding these differences, stakeholders can better appreciate the complementary roles of software testing and Quality Assurance in producing high-quality software.
