软件质量保证(也称为QA)是一系列任务，以防止出现缺陷并确保必须正确实施针对特定应用程序设计的技术，方法，方法和过程。这是软件系统开发中的一个持续过程。
应用程序单元的开发将按照质量保证规范按照其开发顺序进行检查。
质量保证测试确保高质量软件的开发，因为它主要关注软件开发过程中的高质量流程，良好的质量管理体系和定期一致性审核。它是一种管理工具，包括计划和系统的活动以及文档，以防止与质量相关的问题。
质量保证的责任不是任何特定的团队，而是开发团队的每个成员的责任。
质量控制(也称为QC)是一系列任务，通过在开发的软件中识别缺陷和纠正缺陷来确保软件的质量。这是一个被动过程，该过程的主要目的是在发布软件之前纠正所有类型的缺陷。通过使用纠正工具消除问题根源(导致质量降低)来完成该过程，以便软件可以满足客户的要求和高质量。
质量控制的责任是由一个特定的团队组成，该团队称为测试团队，该团队通过验证和纠正工具来测试软件的缺陷。
| Points | Quality Assurance | Quality Control |
|---|---|---|
| Definition | QA is a group of activities which ensures that the quality of processes which is used during the development of the software always be maintained. | QC is a group of activities to detect the defects in the developed software. |
| Focus | The focus of QA is to prevent defects in the developing software by paying attention to processes. | The focus of QC is to identify defects in the developed software by paying attention to testing processes. |
| How | Establishment of the high-quality management system and periodic audits for conformance of the operations of the developing software. | Detecting and eliminating the quality problem elements by using testing techniques and tools in the developed software. |
| What | QA ensures prevention of quality problem elements by using systematic activities including documentation. | QC ensures identification and elimination of defects by using processes and techniques to achieve and maintain high quality of the software. |
| Orientation | QA is process oriented. | QC is product oriented. |
| Type of process | QA is a proactive process. It concerns to improve development so; defects do not arise in the testing period. | QC is a reactive process because it concerns to identify defects after the development of product and before its release. |
| Responsibility | Each and every member of the development team is responsible for QA | Only the specific testing team is responsible for QC |
| Example | Verification is the example of QA | Validation is the example of QC |
