Introduction to Quality Management

Introduction to Quality

• This chapter provides basic definitions of quality and premises of quality management.
• It details stakeholder perspectives on product quality to help software testers understand their role in the software development lifecycle.

Historical Perspective of Quality

• Quality improvement is not a new concept, originating in agricultural practices.
• Early 20th-century British agricultural research focused on crop rotation and maximizing yields with minimal soil degradation.
• Walter Shewhart's work at Bell Laboratories built upon agricultural quality improvement programs.
• Edward Deming and Joseph Juran further developed quality improvement programs globally, with particular focus on Total Quality Management (TQM).
• TQM, heavily adopted by Japanese producers, emphasizes continual improvement through process measurement.
• Modern quality management promotes improvements in quality by increasing customer satisfaction.
• Products are created for customer satisfaction, which is the determining factor for quality.

What is Quality?

• Quality is a multifaceted concept, viewed as a fact or perception based on customer expectations.
• Quality is often defined in terms of meeting and exceeding customer expectations based on features, functionality, price, delivery, and support.
• Customer needs, expressed and implied, play a vital role in defining quality.
• Meeting future needs and technological changes is also a part of quality and helps create a continuous improvement cycle.

Core Components of Quality

• Quality must reflect customer needs, expectations, and requirements.
• There is a need to identify and define metrics for measuring quality to ensure consistency and avoid variations.
• Customer satisfaction and the processes involved in producing the product must be taken into consideration to establish quality measurement.

Quality Management

• Quality management is the responsibility of all members of an organization; it involves managing all functions and procedures within the organization to ensure satisfying customer needs.
• Managing quality encompasses not only the product's attributes but also the processes for producing and delivering it.
• Management is responsible for managing quality throughout the entire process.
• Continuous improvement is essential for quality management.

Quality Management Approaches

• Total Quality Management (TQM) emphasizes continual improvement.
• The Plan-Do-Check-Act (PDCA) cycle is a systematic approach to achieve continuous quality improvements.

Quality in Different Areas

• Stakeholders view quality differently across various industries and products, reflecting specific needs and expectations.

Problem Solving Techniques

• Qualitative and quantitative methods aid problem-solving in quality management.
• Tools and techniques, such as statistical analysis, are crucial for solving problems efficiently and improving overall efficiency.

Problem Solving Software Tools

• Using software tools for analysis, decision-making improves accuracy and speed in problem-solving related to quality management.
• Software tools play a vital role in problem solving for quality control.

Benchmarking

• Benchmarking is a useful technique based on qualitative/quantitative metrics to measure a company's performance against various industry standards or competitors.
• Benchmarking facilitates measuring and improving quality by learning from the best practices/processes from various organizations.

Summary

• The chapter outlines various concepts of quality, from historical perspectives to modern frameworks.
• It discusses how quality affects various stakeholders, including customers, suppliers, and employees.
• It covers the aspects of quality, including problem solving methods and tools and how various industries define quality.
