SQA activities involve formulating quality plans, applying software engineering techniques, conducting reviews, implementing multi-tiered testing, enforcing process adherence, controlling changes, measuring change impact, performing audits, and keeping records. The key goals are to evaluate software quality, monitor adherence to standards and procedures throughout the development lifecycle, and ensure quality is maintained.

Software quality assurance activites
- 2. Software Quality Assurance Activites SQA is the process of evaluating the quality of product and procedures d enforcing adherence to software product standards. It is an umbrella activity that ensures conformance to standard and procedures throughout the SDLC of a software product
- 3. THERE ARE A LARGE NUMBER OF TASKS INVOLVED IN SQA ACTIVITIES •Formulating a quality management plan •Applying software engineering techniques •Conducting formal technical reviews •Applying a multi-tiered testing strategy •Enforcing process adherence •Controlling change •Measuring impact of change •Performing SQA audits •Keeping records and reporting
- 4. FORMULATING A QUALITY MANAGEMENT PLAN One of the tasks of SQA is the formulation of a quality management plan. The quality management plan identifies the quality aspects of the software produ ct to be developed. It helps in planning checkpoints for work products and the development process. It also tracks changes made to the development process based on the results of the checks
- 5. APPLYING SOFTWARE ENGINEERING Application of software engineering techniques helps the software designer to achieve high quality specification . The designer gathers information using techniques such as interviews and FAST. Using the information gather ed, the designer prepares project estimation with the help of t echniques such as WBS, SLOC estimation, or FP estimation
- 6. CONDUCTING FORMAL TECHNICAL REV IEWS Formal technical review (FTR) in conducted to assess the quality and design of the prototype. It is a meeting with the technical staff to discuss the quality requirements of software product and its design quality. Ftr help in detecting an early phase of development . This prevents errors from Percolating.
- 7. APPLYING A MULTITIERED TESTING STRATEGY Software testing is a critical task of SQA activity, which aims at error detection. Unit testing is the first level of testing. The subsequence levels of testing are integration testing and system level testing various . There are testing strategies followed by organization. At times , developers perform unit testing and integration testing with independence testing support. There are also occasions where testers perform functional testing and system level testing with developer support
- 8. ENFORCING PROCESS ADHERENCE This task of SQA emphasizes the need for process adherence during product development. In addition, the development process should also adhe re to procedures defined for product development. Therefore, this is a combination of two tasks, product evaluation and process monitoring.
- 9. PRODUCT EVALUATION Product evaluation ensures that the standards laid down for a proj ect are followed. During product evaluation, the compliance of the software product to the existing standards is verified. Initially, SQA activities are conducted to mon itor the standards and procedures of the project. Product evaluation ensures that the software product reflects the requirements identified in the project management plan
- 10. PROCESS MONITORING Process monitoring ensures that appropriate steps to follow the pro duct development procedures are carried out. SQA monitors processes b y comparing the actual steps carried out with the steps in the documented procedures. Product evaluation and process monitoring ensure that the development and control processes described in the project management plan are correctly carried out. These tasks ensure that the project-re1ated procedures and standards are followed. They also ensure that products and processes conform to standards and procedures. performed
- 11. CONTROLLING CHANGE This task combines human procedures and automated tools to provide a mechanism for change control. The change cont rol mechanism ensures software quality by formalizing requests for change, eval uating the nature of change, and controlling the impact of change. Change control mechanism is implemented during the development and maintenance stage s
- 12. MEASURING IMPACT OF CHANGE Change is inevitable in the SDLC. However, the change needs to be measured and monitored. Changes in the product or process are measured using software quality metrics. Software qua1ity metrics helps in estimating the cost and resource requirements of a project. To control software quality; it is essential to measure quality and then compare it with established standards. Software qua1ity metrics are used to evaluate the effectiveness of techniques and tools, t he productivity of development activities and the qua1ity of products
- 13. PERFORMING SQA AUDITS SQA audits scrutinize the software development process by comparing it to established processes. This ensures that proper control is maintained over the documents required during SDLC. Audits also ensure that the status of an activity performed by the developer is reflected in the sta tus report of the developer.
- 14. KEEPING RECORDS AND REPORTING Keeping records and reporting ensure the collection and circulatio n of information relevant to SQA. The results of reviews, audits, c hange control, testing, and other SQA activities are reported and compiled for futur e reference
