Abstract: For global competitiveness, Indian industries need overall
operational excellence by implementing the proven breakthrough strategy, such
as, Six Sigma. It is one of the most effective breakthrough improvement
strategies having direct impact on bottom line of the organisation. This
quantitative approach aims at improving efficiency and effectiveness of the
organisation, which helps in improving productivity and profitability as well.
From the researches and surveys published so far, it appears that Six Sigma is
not being explored by the Indian industries to its full potential. On global
scenario also much is available regarding techniques of Six Sigma and
its success stories at various multinationals, but very less is reported regarding
step-by-step implementation of Six Sigma in small-scale jobbing industries.
This paper illustrates a real life case study of practising Six Sigma at
small-scale jobbing engineering concern. This paper explains phase wiz
application of all the phases of Define-Measure-Analyse-Improve-Control
(DMAIC), and ultimately shows how Six Sigma can help improving
productivity as well as profitability.
Keywords: productivity; profitability; Six Sigma; Define-Measure-Analyse-
Improve-Control; DMAIC; small-scale industry; Jobbing industries; Indian
industries.
