1. Models of Quality Assessment Done By: Asila AL-harthi Fatma AL-shehhi Fakhriya AL-Omieri Safaa AL-Mahroqi

2. 3.Capability Maturity Model • Is based on the concept of “key Process Areas” that achieve a set of goals important for enhancing process capability. • The CMM is not prescriptive, but a framework to help software organization to gain control of their processes for developing and maintaining software for excellence in engineering and management.

3. The CMM recognizes five maturity levels:

4. Disciplined process Step 1: Creating a profile Step 2: Clarifying Goals and Objectives Step 3: Analysis Step 4: Financial Plan Step 5: Independent Implementation Step 6: Monitoring and Reporting

5. Initial: the software process is characterized as ad hoc, and occasionally even chaotic. Few process are defined, and success depends on individual efforts. • Repeatable: basic project management is process are established to track cost, schedule and functionality.

6. Defined: The software process for both management and engineering are documented, standardized and integrated into a standard software process for the organization. • Managed: detailed measures of software process and products are quantitatively understood and controlled.

7. Optimizing: Continuous process improvements is enabled by quantitative feedback from the process and piloting innovative ideas and technologies.

8. 4. Six Sigma Model • Letter in Greek alphabet used to donate standard deviation in statistics. • The objective: • Reduce variation and defects • Increase customer satisfaction. • Increase profit.

9. Ways to view Six Sigma • Metric • Philosophy • Methodology

10. Six Sigma as Metric • Statistical expression that denotes a population’s standard deviation and is a measure of variation about mean.

11. Six Sigma as Philosophy • It concerns with its customer focus and creative process improvements. • There is a strong relation between level of defects, cost and customer satisfaction

12. Six Sigma as Methodology • It emphasize process of achieving the Six Sigma level • In order to implement Six Sigma in an institution, it needs people who are trained in the methodology of six sigma.

13. Six Sigma includes five steps.

14. Total Quality Management Model • It is a philosophy that subsumes earlier methods of inspection, quality control and quality assurance. • TQM is a people drive process (it involves changes in people’s attitude primarily. • It deals with process orientation and continuous improvement of the process.

15. TQM Components • The customer: can be anyone who receives or is affected by the product, process or service and (can be external or internal). • Continuous improvement: it should aims towards ‘zero defects’.

16. Update and training: the focus should be to reinforce employee commitment and have a positive effect on morale leading to productivity gains. • Teamwork: the involvement of all stakeholders is key to success. • Measurement: monitor the progress and review the objectives.

17. Total Quality Care • Four core activities that takes care of quality in higher education: • Teaching and learning • Students assessment • Staff development • curriculum
