Function of software quality assurance lecture 2
The document discusses the function of software quality assurance (SQA). It outlines that SQA includes auditing, reviews, and process checks to enable independent reviews of work. It also requires knowledge of statistics, quality control principles, software processes, and dealing with people. Establishing an SQA function first requires deciding how important quality is versus schedules. It then ensures standards, procedures, reviews, documentation, change control, testing high-risk areas, and satisfying tasks before starting new ones. SQA enforces project and development standards, improving quality and cost-effectiveness. Its objectives are to improve quality through monitoring software and processes, ensuring compliance, and identifying inadequacies.

- 1. Function of Software Quality Assurance By Mr. Fazal Wahab
- 2. The SQA Function The critical challenge for any quality program is to devise a mechanism for enabling independent reviews of the work done by others. The need is to focus on SQA methods SQA activities includes Auditing and Reviews in addition to walkthroughs and process checks. Quality Assurance function is what is required to establish a strong quality program in an organization.
- 3. The SQA Function It includes: – Knowledge of statistical methods – Quality control principles – The software process and – An ability to deal effectively with people The role of Software Quality assurance to do the tracking of activities.
- 4. The SQA Function Before establishing an SQA function it is essential to first decide how important software quality is to the organization – Is it more important than meeting a critical delivery schedule? – How much “Quality” is important? – Should the product be delayed to fix 1 more bug, or 10 more or 100 more.
- 5. Establishing a Quality Assurance Program in the organization The following must be ensured: – An appropriate development methodology is in place. – The projects use standards and procedures in their work – Independent review and audits are conducted – Documentation is produced to support maintenance and enhancement – The documentation produced during and not after development – Mechanisms are in place and used to control changes – Testing emphasizes all the high-risk product areas
- 6. Establishing a Quality Assurance Program in the organization – Each software task is satisfactorily completed before the succeeding one is begun. (Phase end inspection) – Deviations from standards and procedures are exposed as soon as possible (Waivers and Deviations) – The quality control work is itself performed against establishment standards – The SQA plan and the software development plan are compatible.
- 7. The Benefits of SQA Function SQA is used in two contexts: – As a role (Software Quality Analyst) – And a function (Software Quality Assurance) Enforcement of Project management Standards: – 76 % of the projects were successful Enforcement of Development Standards – IBM reported Software quality improvement of three to five times over an eight-years period. SQA function is found increasingly advantageous, from both product quality and cost-effectiveness standpoints.
- 8. Objectives and Needs for SQA Function To improve software quality by appropriate monitoring both the software and the development process that produces it. To ensure full compliance with the established standards To ensure that any inadequacies in the product, the process, of the standards are brought to management attentions so these inadequacies can be fixed.
