Six sigma is a set of tools and strategies for process improvement. Our six sigma study revealed that the automobile manufacturing unit’s major focus was on customer satisfaction and quality of the product. As per six sigma concept, the emphasis was given first on environmental management which is a mandatory requirement. After our study, an ETP was installed by the unit to remove heavy metals, dyes and other chemical impurities from their waste water, so that the treated effluent meets the norms prescribed by the pollution control board. The study indicated that automobile industries may use six sigma tools to make their system environment friendly and comply with legal regulation to protect our environment.
