Process control at Polaroid ChulanuntThaiyanunt Basing your analysis on both quantitative and qualitative tools, what evidence is there that quality is getting better? Pod Weightcontrol Accordingto PodWeightcontrol chart inAppendix,the podweightperformance variabilityiswithinthe control limit(between 2.774- 2.835), whichmeansthe processisin control. Thisindicatesthe qualityis gettingbettersince the PodWeightdefectrate isnormal (PodWeightmeasurementisapart of defect reportissuedbyoperator,whichcontinue 1% afterGreenlightimplementation) andincontrol,although theyreduce the numberof qualitycontrol samples. However,eachaverage of sample of the lastfive shiftshasdecreasingtrend.Therefore,Polaroidmightwanttoinvestigate the cause before the process isout of control. LessQualityControl expense Since qualitycontrol activitiesdonotaddvalue tothe Polaroidcamera, acompanynormallywantsto reduce the cost of qualitycontrol as muchas possible.InPolaroid,the qualitycontrol process itself can increase the defectrate andmakesthe samplingproducttobe reworked.
