The concept of quality management has evolved significantly since the early 20th century, beginning with W. A. Shewhart's statistical chart for product variables and expanding through the contributions of W. Edwards Deming and Joseph M. Juran, who introduced Total Quality Management (TQM) in Japan. Over time, quality management practices have adapted to meet the demands of a changing marketplace, with methodologies like Six Sigma improving productivity and reducing defects across various sectors, including technology and government. The shift from waterfall to agile methodologies has redefined quality as a collective responsibility rather than solely a tester's duty, emphasizing that all team members, including product owners, developers, and testers, contribute to ensuring quality throughout the project lifecycle. Effective communication and collaboration among team members, supported by tools like the Test At Scale platform, enhance quality assurance by providing early insights and reducing testing durations. Ultimately, quality is viewed as a continuous process akin to security, where each team member plays a vital role in maintaining and improving standards to ensure project success.
