1. Software Quality Assurance

2. Software Quality Software quality is defined as the quality that ensures customer satisfaction by offering all the customer deliverables on performance, standards and ease of operations.

3. Software Quality Assurance What is “quality”? IEEE Glossary: Degree to which a system, component, or process meets (1) specified requirements, and (2) customer or user needs or expectations ISO: the totality of features and characteristics of a product or service that bear on its ability to satisfy specified or implied needs

4. Quality Control What is quality control -- the series of inspections, reviews, and test used throughout the develop cycle of a software product Quality control includes a feedback loop to the process. Objective ---> minimize the produced defects, increase the product quality Key concept of quality control: --> compare the work products with the specified and measurable standards

5. Cost of Quality Cost of quality -->Quality is produced at cost. The cost of quality includes all costs incurred in the process of creation, generation, control and maintenance of quality or perform quality related work Quality cost includes: - Prevention cost: - quality planning - formal technical reviews - testing equipment - training to personnel

6. What is Software Quality Assurance (SQA)? “Set of systematic activities providing evidence of the ability of the software process to produce a software product that is fit to use”

7. What is SQA? Monitoring the processes – Provides management with objective feedback regarding process compliance to approved plans, procedures, standards, and analysis

8. What is SQA? Monitoring the products – Focus on the quality of product within each phase of the SDLC e.g., requirements, test plan, architecture, etc. – Objective: identify and remove defects throughout the lifecycle, as early as possible

9. Quality Standards Organizations Quality assurance systems help organization ensure that their deliverables meet customer requirements. They encompass a wide variety of tasks during a product’s lifecycle, which includes planning,controlling,testing, and developing the quality process. There are various quality assurance standards, which ensure that the product developed is effective and reusable. Some of the significant quality standards are described below:

10. Standard Definition  “Standard is a published specification that establishes a common language, and contains a technical specification or other precise criteria and is designed to be used consistently, as a rule, a guideline, or a definition”.

11. History of ISO ISO, founded in 1947, is a worldwide federation of national standards bodies from some 100 countries, with one standards body representing each member country. Member organizations collaborate in the development and promotion of international standards.

12. Overview  ISO (International Organization for Standardization) is the world's largest developer and publisher of International Standards.  ISO is a network of the national standards institutes of over 160 countries

13. Scope  ISO has more than 16500 International Standards and other types of normative documents16500 International Standards  ISO's work program ranges from standards for traditional activities, such as agriculture and construction, through mechanical engineering, manufacturing and distribution etc.

14. Description about member countries of ISO ISO has three membership categories: Member bodies: Be the most representative standards body in each country These are the only members of ISO that have voting rights.

15. Description about member countries of ISO (Count.) Correspondent members: These countries do not follow ISO standards and they also do not have their own standards organizations e.g. Afghanistan. Subscriber members: Countries having small economies. They pay reduced membership fees, but can follow the development of standards.

16. History The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is an international non-profit, professional organization for the advancement of technology related to electricity. It has the most members of any technical professional organization in the world, with more than 370,000 members in around 160 countries.

17. History Cont. The IEEE formed in 1963 with the merger of  AIEE (American Institute of Electrical Engineers, formed in 1884),  IRE (Institute of Radio Engineers, formed in 1912). IEEE From its earliest origins, has  Advanced the theory and application of electrot echnology and allied sciences  Served as a catalyst for technological innovation;  and supported the needs of its members through a wide variety of programs and services.

18. History Cont. AIEE, IRE Merge to form IEEE  In 1961, the leadership of both the IRE and the AIEE sought to resolve these difficulties through consolidation. A merger plan was formulated and approved, becoming effective on 1 January 1963.

19. Microsoft Solution Framework (MSF) MSF is a flexible, interrelated series of models that can guide an organization through assembling the resources, people, and techniques needed to bring technology infrastructure in line with business objectives.

20. MSF Models MSF consists of two models 1. MSF two Models 2. MSF Process/Governance Models

21. 1. MSF Team Model This describes the role of various team members in a software development project. The team model roles are: Product Management: Mainly deals with customers and define project requirements, also ensures customer expectations are met. Program Management: Maintains project development and delivery to the customer

22. 1. MSF Team Model Architecture: Responsible for solution design, making sure the solution design optimally satisfies all needs and expectations Development: Develops according to the specifications. Test: Tests and assures product quality Release/Operations: Ensures smooth deployment and operations of the software User Experience: Supports issues of the users.

23. Process Model: Process model defined order of activities related to the project and represent life cycle of project. There are four phases in the process model: 1. Envisioning 2. Planning 3. Developing 4. Stabilizing
