Process and Product Quality: n The quality of a developed product is influenced by the quality of the production process. n This is important in software development as some product quality attributes are hard to assess. n However, there is a very complex and poorly understood relationship between software processes and product quality. 16/03/2018 Quality Management, www. moseslsinggih. org 28
Process-based Quality: n There is a straightforward link between process and product in manufactured goods. n Care must be taken not to impose inappropriate process standards - these could reduce rather than improve the product quality. 16/03/2018 Quality Management, www. moseslsinggih. org 29
Practical Process-based Quality: n Define process standards such as how reviews should be conducted, configuration, management, etc. n Monitor the development process to ensure that standards are being followed. n Don’t use inappropriate practices simply because standards have been established. 16/03/2018 Quality Management, www. moseslsinggih. org 30
Quality Assurance and Standards: n Standards are the key to effective quality management. n They may be international, organizational or project standards. n Product standards define characteristics that all components should exhibit e. g. a common programming style. n Process standards define how the software process should be enacted. 16/03/2018 Quality Management, www. moseslsinggih. org 31
Importance of Standards: n Encapsulation of best practice- avoids repetition of past mistakes. n They are a framework for quality assurance processes - they involve checking compliance to standards. n They provide continuity - new staff can understand the organisation by understanding the standards that are used. 16/03/2018 Quality Management, www. moseslsinggih. org 32
Problems with Standards: n They may not be seen as relevant and up-to- date by software engineers. n They often involve too much bureaucratic form filling. n If they are unsupported by software tools, tedious manual work is often involved to maintain the documentation associated with the standards. 16/03/2018 Quality Management, www. moseslsinggih. org 33
Standards development: n Involve practitioners in development. Engineers should understand the rationale underlying a standard. n Review standards and their usage regularly. Standards can quickly become outdated and this reduces their credibility amongst practitioners. n Detailed standards should have associated tool support. Excessive clerical work is the most significant complaint against standards. 16/03/2018 Quality Management, www. moseslsinggih. org 34
ISO 9000: n An international set of standards for quality management. n Applicable to a range of organisations from manufacturing to service industries. n ISO 9001 applicable to organisations which design, develop and maintain products. n ISO 9001 is a generic model of the quality process that must be instantiated for each organisation using the standard. 16/03/2018 Quality Management, www. moseslsinggih. org 35

Quality Management System: Management system to direct and control an organisation with regard to quality – ISO 9000: 2000 Quality Management Quality Planning Quality Assurance Quality Control Criteria driven Prevention driven Inspection driven 16/03/2018 Quality Management, www. moseslsinggih. org 39
Quality Management Components n Quality Planning n It identifies the standards and determines how to satisfy those standards. n It lays out the roles and responsibilities, resources, procedures, and processes to be utilized for quality control and quality assurance. n Quality Assurance n It is the review to ensure aligning with the quality standards. An assessment will be provided here. n Planned and systematic quality activities. n Provide the confidence that the standards will be met. 16/03/2018 Quality Management, www. moseslsinggih. org 40
Quality Control – Inspection Driven n Quality Control n It addresses the assessment conducted during Quality Assurance for corrective actions. n Measure specific results to determine that they match the standards. n Use of Statistical Process Control (SPC) : a methodology for monitoring a process to identify special causes of variation and signal the need to take corrective action when appropriate. n SPC relies on control charts. 16/03/2018 Quality Management, www. moseslsinggih. org 41
What is a Control Chart? n A control chart is a presentation of data in which the control values are plotted against time. n Control charts have a central line, upper and lower warning limits, and upper and lower action limits. n Immediate visualisation of problems. 16/03/2018 Quality Management, www. moseslsinggih. org 42

Taguchi’s Contribution n In the early 1980 s, Prof. Genechi Taguchi introduced his approach to using experimental design for 1) 2) 3) Designing products or processes so that they are robust to environmental conditions. Designing/developing products so that they are robust to component variation. Minimizing variation around a target value. n By robust, we mean that the product or process performs consistently on target and is relatively insensitive to factors that are difficult to control. 16/03/2018 Quality Management, www. moseslsinggih. org 78
Taguchi Philosophy n 3 stages in a product’s (or process’s) development: 1) 2) 3) 16/03/2018 System design: uses scientific and engineering principles to determine the basic configuration. Parameter design: specific values for the system parameters are determined. Tolerance design: determine the best tolerances for the parameters. Quality Management, www. moseslsinggih. org 79
Taguchi Philosophy n Recommends: statistical experimental design methods have to be used for quality improvement, particularly during parameter and tolerance design phases. n Key component: reduce the variability around the target (nominal) value. 16/03/2018 Quality Management, www. moseslsinggih. org 80
