Quality Circle (QC) is a group of workers from a shop or department who meet regularly under the leadership of foreman or section head to examine work problems that affect the quality of output, and to recommend solutions to these problems. The number of workers is usually six to eight, and membership is absolutely voluntary. The success of actual quality circle depends on the contribution that can be made by solving the particular problem. QCs have demonstrated that, in the right hands and used in the right way they can work anywhere.
