Quality management of the production process using Six sigma methodology

Abstract

Six Sigma concept is presented in literature as a technique and a philosophy stemming from the desire to eliminate waste and improve performances as much as technically possible. The idea of Six Sigma is to reduce the number of defects to the lowest possible level, to reduce costs and production time, and to increase productivity and improve business results. The goal of the Six Sigma principles is to achieve 'perfection' with no more than 3.4 defects, errors or omissions per million opportunities. Therefore, this paper provides a brief description of statistical groundings underlying the Six Sigma methodology.

Tehnika i filozofija, zasnovana na želji da se otkloni škart i poboljšaju performanse koliko god je to tehnički moguće se u literaturi naziva Šest sigma koncept. Ideja Šest sigme je svesti broj defekata na najmanji mogući nivo, smanjiti troškove i vreme proizvodnje, te povećati produktivnost i poboljšati poslovne rezultate. Cilj principa Šest sigma je postizanje "savršenstva" kroz najviše 3,4 defekta, greške ili propusta u milion šansi. Stoga u ovom radu nudimo kratki osvrt na same statističke osnove na kojima se temelji Šest sigma metodologija.
