2 Software Quality Assurance It is the Process of verifying or determining whether products or services meet or exceed customer expectations It is the Process of verifying or determining whether products or services meet or exceed customer expectations QA is a process driven approach with specific steps to help define and attain goals, the process considers design, development, production and service. QA is a process driven approach with specific steps to help define and attain goals, the process considers design, development, production and service. Shewhart cycle to determine QA-developed by Dr. W. Edwards Deming, it includes Plan, Do, Check, Act. Shewhart cycle to determine QA-developed by Dr. W.

3 Formal SQA Process

4 Plan The Key to Quality Assurance is proper validation and documentation, it starts with a detailed plan. The Key to Quality Assurance is proper validation and documentation, it starts with a detailed plan. The plan documents the expectations of the customer, it includes the techniques, procedures and methodologies that will be used to assure timely delivery of the software that meets specified requirements within project resources. The plan documents the expectations of the customer, it includes the techniques, procedures and methodologies that will be used to assure timely delivery of the software that meets specified requirements within project resources.

5 Do This includes to implement the solution or process change. This includes to implement the solution or process change. Monitor results and collect data. Monitor results and collect data.

6 Check Use data to analyze the results of the change and determine whether it made a difference. Use data to analyze the results of the change and determine whether it made a difference. Ensure that any deviations in software or work products are documented and handled according to a documented procedure. Ensure that any deviations in software or work products are documented and handled according to a documented procedure. Record any evidence of noncompliance and reports them to management. Record any evidence of noncompliance and reports them to management.

7 Act Purpose is to find defects (errors) before they are passed on to another software engineering activity or released to the customer. Purpose is to find defects (errors) before they are passed on to another software engineering activity or released to the customer. Software engineers (and others) conduct formal technical reviews (FTR) for software engineers. Software engineers (and others) conduct formal technical reviews (FTR) for software engineers. Using informal technical reviews (walkthroughs or inspections) is an effective means for improving software quality. Using informal technical reviews (walkthroughs or inspections) is an effective means for improving software quality.

8 Formal Technical Reviews - 1 Involves 3 to 5 people (including reviewers) Involves 3 to 5 people (including reviewers) Advance preparation (no more than 2 hours per person) required Advance preparation (no more than 2 hours per person) required Duration of review meeting should be less than 2 hours Duration of review meeting should be less than 2 hours Focus of review is on a discrete work product Focus of review is on a discrete work product Review leader organizes the review meeting at the producer's request. Review leader organizes the review meeting at the producer's request.

9 Formal Technical Reviews - 2 Reviewers ask questions that enable the producer to discover his or her own error (the product is under review not the producer) Reviewers ask questions that enable the producer to discover his or her own error (the product is under review not the producer) Producer of the work product walks the reviewers through the product Producer of the work product walks the reviewers through the product Recorder writes down any significant issues raised during the review Recorder writes down any significant issues raised during the review Reviewers decide to accept or reject the work product and whether to require additional reviews of product or not. Reviewers decide to accept or reject the work product and whether to require additional reviews of product or not.

10 Why do peer reviews? To improve quality. To improve quality. Catches 80% of all errors if done properly. Catches 80% of all errors if done properly. Catches both coding errors and design errors. Catches both coding errors and design errors. Enforce the spirit of any organization standards. Enforce the spirit of any organization standards. Training and insurance. Training and insurance.

11 Formality and Timing Formal review presentations Formal review presentations resemble conference presentations. resemble conference presentations. Informal presentations Informal presentations less detailed, but equally correct. less detailed, but equally correct. Early Early tend to be informal tend to be informal may not have enough information may not have enough information Later Later tend to be more formal tend to be more formal Feedback may come too late to avoid rework Feedback may come too late to avoid rework

12 Formality and Timing Analysis is complete. Analysis is complete. Design is complete. Design is complete. After first compilation. After first compilation. After first test run. After first test run. After all test runs. After all test runs. Any time you complete an activity that produce a complete work product. Any time you complete an activity that produce a complete work product.

13 Review Guidelines Keep it short (< 30 minutes). Keep it short (< 30 minutes). Don’t review product fragments. Don’t review product fragments. Use standards to avoid style disagreements. Use standards to avoid style disagreements. Let the coordinator run the meeting and maintain order. Let the coordinator run the meeting and maintain order.

14 Statistical Quality Assurance Information about software defects is collected and categorized Information about software defects is collected and categorized Each defect is traced back to its cause Each defect is traced back to its cause Using the Pareto principle (80% of the defects can be traced to 20% of the causes) isolate the "vital few" defect causes Using the Pareto principle (80% of the defects can be traced to 20% of the causes) isolate the "vital few" defect causes Move to correct the problems that caused the defects Move to correct the problems that caused the defects

15 Quality related certifications ISO 9000 ISO 9000 SEI – CMM Model SEI – CMM Model People Capability Maturity Model (P-CMM) People Capability Maturity Model (P-CMM) CMMi Model CMMi Model COPC 2000 COPC 2000 eSCM eSCM BS 7799 BS 7799 Six Sigma Six Sigma

16 ISO 9000  It is series of an international set of documents on quality assurance.  ISO model for quality assurance in design/development, production, installation and servicing.  ISO model for quality production and installation.  ISO model for quality assurance in final inspection and test.  Two supporting guidelines documents, namely ISO 9000 and ISO 9004

17 SEI – CMM Model The CMM describes an improvement path from an adhoc, immature to a mature, disciplined software process. The CMM describes an improvement path from an adhoc, immature to a mature, disciplined software process. It covers practices for planning, engineering and managing software development and mantainance. It covers practices for planning, engineering and managing software development and mantainance. The CMM is composed of five maturity levels The CMM is composed of five maturity levels Each maturity level provides a layer in the foundation for continuous process improvement. Each maturity level provides a layer in the foundation for continuous process improvement.

18 P - CMM It is a process at managing and developing an organisation's work force and adopts the maturity framework of Capability Maturity Model for software.
