The concept of continuous improvement has a rich historical development of projects and processes. While its origins can be traced back to early philosophies of management, its contemporary iterations have been influenced by major historical developments in quality management, production, and organizational theory. Below is an overview of the historical development of continuous improvement:

1-Early management philosophy (late 19th to early 20th century)

  • The roots of continuous improvement can be traced back to early management thinkers such as Frederick Winslow Taylor, Henry Feyol, and Henry Ford.
  • Taylor’s scientific design principles emphasized systematic approaches to improving productivity and efficiency in manufacturing through the use of various benchmarks and time studies.
  • Fayol’s principle of entrepreneurship emphasized the importance of planning, organizing and monitoring organizational activities to achieve continuous improvement in performance.
  • Henry Ford’s use of assembly line production at the Ford Motor Company revolutionized manufacturing by dramatically increasing productivity and reducing costs through continuous process improvements.

2-Total Quality Management (TQM) Group (mid-20th century)

  • The TQM movement emerged in the 1950s and 1960s, influenced by the quality management philosophy of quality gurus such as W. Edwards Deming, Joseph Juran and Philip Crosby.
  • Deming 14 Points Management’s Plan-Do-Check Act (PDCA) cycle laid the foundation for modern quality improvement strategies, emphasizing the importance of continuous improvement, audit process control, and customer focus.
  • Juran introduced the concept of the “quality triad”, which includes quality planning, quality control and quality improvement, and highlighted the need for continuous efforts to processes and processes will be improved.
  • Crosby popularized the concept of “no fault” and emphasized the importance of prevention rather than detection in order to achieve continuous qualitative improvement.

3-Lean Manufacturing (Late 20th Century)

  • The principles of lean production originated from the Toyota Production System (TPS) developed by means of Toyota in the 1950s and Sixties.
  • TPS emphasised the elimination of waste (muda), standardized work, non-stop improvement (kaizen), and just-in-time production to gain operational excellence.
  • Lean manufacturing principles, inclusive of fee circulate mapping, kanban, and 5S, have been later popularized with the aid of books like “The Machine That Changed the World” through James Womack, Daniel Jones, and Daniel Roos.

4-Six Sigma (Late 20th Century)

  • Six Sigma emerged as a excellent improvement method inside the overdue Nineteen Eighties and early 1990s, initially advanced by Motorola and later popularized via General Electric under the management of Jack Welch.
  • Six Sigma focuses on reducing variant and defects in methods by using the use of statistical strategies, DMAIC (Define, Measure, Analyze, Improve, Control) methodology, and a records-driven approach to trouble-fixing.

5-Agile and Continuous Improvement in Software Development (Late 20th Century to Present)

  • In the software improvement enterprise, the Agile method emerged within the overdue 20th century as a reaction to traditional waterfall improvement techniques.
  • Agile emphasizes iterative improvement, customer collaboration, and continuous development via ordinary comments, retrospectives, and adaptive planning.

6-Continuous Modernization Program:

  • Today, continuous improvement is embedded in a variety of business processes and methodologies, including Lean Six Sigma, Agile, Total Productive Maintenance (TPM), and Continuous Improvement Process (CIP), among others
  • This framework combines elements from historical quality management philosophies with contemporary thinking to drive continuous improvement in a variety of organizational settings.


In summary, historical continuous improvement is characterized by different business philosophies, strategies for quality improvement and production processes aimed at achieving continuous improvement in improving efficiency, quality and performance across industries and sectors.
