Dear friends, I am glad to release our technical video on the subject of ‘Sigma Level vs Defective Proportion and PPM’! In this video, I have tried to explain the definition of sigma level in the context of the relation between tolerance and standard deviation sigma. Sigma Level assessment is an essential step in Six Sigma projects. In this video, I have explained the logic of 1.5sigma shift as was developed in Motorola. The sigma level vs ppm calculations are explained and illustrated using an Excel screen recording. Hope you find this video interesting!
