Evolution of Continuous Quality Improvement As A Methodology

Continuous improvement is an ongoing effort to improve products, services or processes. These efforts can seek “incremental” improvement over time or “breakthrough” improvement all at once.

Among the most widely used tools for continuous improvement is a four-step quality model—the plan-do-check-act (PDCA) cycle, also known as Deming Cycle or Shewhart Cycle:

Plan: Identify an opportunity and plan for change.

Do: Implement the change on a small scale.

Check: Use data to analyze the results of the change and determine whether it made a difference.

Act: If the change was successful, implement it on a wider scale and continuously assess your results. If the change did not work, begin the cycle again.

Other widely used methods of continuous improvement — such as Six Sigma, Lean, and Total Quality Management — emphasize employee involvement and teamwork; measuring and systematizing processes; and reducing variation, defects and cycle times.

Milestones in the path of Quality management

Walter A. Shewhart, (1931) developed & used control charts during his tenure at Hawthorne plant of Western Electric and is known as the father of Statistical Quality Control (SQC) he brought together the disciplines of statistics, engineering and economics.

Soon after, W. Edwards Deming (1986) developed a list of 14 points in which emphasized the need for change in management structure and attitude.

These are:-

1.Create constancy of purpose for improvement of product and service.
2.Adopt a new philosophy.
3.Cease dependence on inspection to achieve quality.
4.End the practice of awarding business on the basis of price tag alone. Instead, minimize total cost by working with a single supplier.
5.Improve constantly & forever every process by planning, production, & service.
6.Institute training on the job.
7.Adopt & institute leadership.
8.Drive out fear.
9.Break down barriers between staff areas.

15.Institute a vigorous program of education & self-improvement for everyone.
16.Put everybody in the company to work to accomplish the transformation.

In addition, Joseph M. Juran developed the Juran Trilogy, three managerial processes- Quality Planning, Quality Control, and Quality Improvement-for use in managing the quality.

This approach to quality improvement includes-

1.Create awareness of the need & opportunity for improvement.
2.Mandate quality improvement; make it a part of every job description.

6.Give recognition to the winning teams.
7.Propagandize the results.
8.Revise the reward system to enforce the rate of improvement.
9.Maintain momentum by enlarging the business plan to include goals for quality improvement.

Joining the lead was Philip B. Crosby, who originated the zero defects concept.

His 14 steps to Quality Improvement are-

1.Make it clear that management is committed to quality.
2.Form quality improvement teams with representative from each department.
3.Determine how to measure where current & potential quality problems lie.
4.Evaluate the cost of quality & explain its use as a management tool.
5.Raise the quality awareness & personal concern of all employees.
6.Take formal action to correct problems identified through previous steps.
7.Establish a committee for zero defects program.
8.Train all employees to actively carry out their part of quality improvement program.
9.Hold a “zero defect day” to let all employees realize that there has been a change.
10.Encourage individuals to establish improvement goals for themselves & their groups.
11.1Encourage employees to communicate to management the obstacles they face in attaining their improvement goals.
12.Recognize & appreciate those who participate.
13.Establish quality council to communicate on regular basis.
14.Do it all over again to emphasize that the quality improvement program never ends.

Also, Armand V. Feigenbaum originated the concept of Total Quality Control listing three steps to quality:

1.Quality Leadership

3.Organizational Commitment

Kaoru Ishikawa (1985) developed the cause-and-effect diagram, the following points summarize the philosophy.
