Hemant Urdhwareshe — New Contributor

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!

Dear friends, we are happy to release this video on Process Capability. this is our 93rd video! In this video, Hemant Urdhwareshe, Fellow of ASQ, explains the basic concepts of process capability indices Cp and Cpk with an illustrative example. Hemant has also explained how to validate whether the data is normally distributed with histogram and normal probability plotting. Hemant has further explained the interpretation of the results of study and suggested improvement actions.

Dear friends, we are happy to release our 90th technical video! In this video, Hemant Urdhwareshe, Fellow of American Society for Quality (ASQ), explains the various functions in reliability mathematics. Hemant has explained Probability Density Function (PDF), Cumulative Failure Distribution Function (CDF), Reliability Function and the Hazard Function. Hemant has also briefly explained the mathematical derivations of these functions as well as their relationships. In addition, the video includes an application example of estimating B02 life when the hazard function is known. The video is little long, so viewers are requested to be patient and watch the complete video. This will be very useful in preparing for the Certified Reliability Engineer Exam conducted by ASQ.

Dear friends, we are happy to release this 85th video in our channel ‘Institute of Quality and Reliability’! In this video, Hemant Urdhwareshe has explained the concept of statistical tolerancing tolerance stack-up! Conventional Extreme Value Analysis (EVA) can result in increased manufacturing costs! Statistical tolerancing is more optimistic method of analysing tolerances and can reduce manufacturing costs! Concepts of loop diagram, additivity of variances are also explained briefly in the video with a practical application case study of tolerance stack-up analysis.
