In the manufacturing firms, hospitals, banks, schools and research institutes etc., total customer satisfaction with products and services have very much importance and also necessary for their survival. Quality services and reducing wastages of all types are the primary need of every organisation. Quality Circle is (QC) is one of the techniques that can be utilised to solve industrial problems and can reduce the rejection level. In present paper, QC concept is implemented to solve wastage problem by taking a real case study of an automobile industry. The observed data was analysed through various problem solving techniques such as 80/20 rule and fishbone diagram etc. Finally, Why-Why analysis was carried out to identify the root cause of the problem and suggested actions to solve the problem. The following results were obtained: Gradually reduction in materials wastage minimises the rejection and hence reduces the overhead expenses of the firm. Further, QC helps in motivating employees to do their best for the organisation, which not only improves the productivity of the organisation, but also helps in discovering hidden talent and creative skill of the workforce. Finally, QC helps in developing the sense of belongingness towards organisations.

Keywords- Quality circle, Quality control tools, Problem solving techniques, Why-Why analysis, Automobile industry.
