Six Sigma is used for produce high-quality
products with the low cost. This research defines a stepby-step guide, using the DMAIC (Define, Measure,
Analyse, Improve, and Control) methodology. Also the
effectiveness of the DMAIC has been calculated with a
case study carried out in a south Indian industry. This
methodology is mainly used to recognize the hidden waste
and costs, identify and eliminate defects, increase profit
margins, increase the employee’s level of commitment and
fulfillment, on time delivery and in turn to improve
customer satisfaction. In this research, the prime focus is
on improving customer satisfaction in the pump
manufacturing industry. This study mainly used on
employee job fulfillment and executing Six Sigma is also
studied. It shows that members of Six Sigma have
experienced positive changes in most job fulfillment
measures. Implications of the evaluation investigated with
direction for further action of the company.
In pump manufacturing industry, during
manufacturing of submersible pump ovality occurs in
pump sleeve. The manufacturing process of pump sleeve
consists of following process, metal cutting, rolling, tig
welding, plunging, ring welding, slotting and buffing.
Here ovality problem occurs during the welding
followed by plunging operation. To neglect this ovality
problem, instead of welding followed by plunging
operation deep drawing operation is suggested.
