Six Sigma implementation to minimise weight variation for Baby Lido Diaper manufacturing company Academic Article uri icon


  • The increasing demand in baby diaper products in addition to customer requirements has compelled companies to improve the quality of their production processes. This paper presents a customised Six Sigma procedure to reduce weight variation in diaper products. To this end, a define, measure, analyse, improve and control (DMAIC) model is developed and applied at a production line at a local company to identify and control root causes. Thorough analysis of collected data revealed that excess fluff, sap and pulp are the main causes for variations. As a result, several changes have been adopted at the improvement phase; these improvements decreased defects per million opportunities (DPMO) form 292,157 to 88,152 and increased the sigma level from 2.05 to 2.85.
