INTRODUCTION
OVERVIEW OF SIX-SIGMA
The method is a well-planned mechanism to drive data and remove the fault in every system of transaction
and servicing of product. As per the principle the standard it should not cross 3.4 defects in per million option
[1]. The two sub division of this application as follows:
i. Defining, Measuring, Analysing, Improving, Controlling
ii. Defining, Measuring, Analysing, Designing, Verifying
CONTEXT OF SIX-SIGMA
DMAIC six-sigma methodology has found application in many industries such as in USA during early 1980’s
in Motorola, Generic Electric and in UK in recent years it has found application in construction industries
(Coastain, O’Rouke, Bechey and Emcor Rail (CORBER)), IN Korea in Doosan Heavy Industries and
Construction Company. Bechtel Corporation (an international engineering, procurement and construction
management company), has already implemented six-sigma. Asia’s commercial aviation service companies
(MROs), applied six-sigma for transforming Boeing 747 passenger plane [2].
THE CURRENT APPLICATIONS, PRACTICES AND IMPLEMENTATION OF SIX-SIGMA
METHODOLOGY
DMAIC explain by Rodney and Mathew in detail effectively implemented by construction companies. In
define phase, company sets project goals and biggest opportunities are address. Next, in measure stage,
documentation of current process is done and project’s base line performance assessed. Identification and
analysis of top causes tackling process of project are done. In improve phase top causes that were analyzed in
analysis phase are completely understood and any changes necessary are made. Final control stage changes
