Answers:
The basic concept of Quality Circle (QC) first originated in Japan in the 1960s. It was based on the participatory style of management, with an assumption that productivity will improve through the uplift of the morale of the employees and make them self-dependent in their area of work. QC is typically an informal group of workers that consists of operators, supervisors, and managers who come together to invent or improve ways to create better products and services.
