Your Reliability Engineering Professional Development Site
Institute of Quality and Reliability (IQR) was established in Nov. 2005, with primary objective to help Industries for improving their quality and business performance. IQR also supports individuals aspiring to improve their knowledge and skills in Quality and Reliability.
This article series (videos) is dedicated to all those who want to learn and contribute to quality and reliability improvement to make this world better! Videos are created by Hemant Urdhwareshe and team. Hemant is a Fellow of American Society for Quality (ASQ) and is certified by ASQ as Six Sigma Master Black Belt, Reliability Engineer (CRE), Quality Manager (CMQ/OE) and Quality Engineer (CQE). He has 42 years of experience and wants to share his knowledge and experience with those who wish to acquire it!
Dear friends, I am happy to release my 106th technical video. In this video, I have explained how to use the open source JASP software to create and analyse Full Factorial Experiment. I have illustrated this with an application example of how to maximize fatigue strength of a crankshaft. Crankshaft is a critical component used in internal combustion engines.

Dear friends, wish you all a very happy 2026! After a long gap, I am happy to release my 104th video! As we all know, statistical analysis software is becoming quite expensive to buy and maintain! On this background, it is good to know that there is a powerful open-source statistical analysis software ‘JASP’ which is completely free! While JASP is free, its capabilities are excellent and can be a good substitute for a commercial software! I thought of sharing some information about this free open-source software JASP! In future, I intend to demonstrate how to use JASP for performing statistical analyses in few more videos. Your feedback is welcome!

Dear friends, we are happy to release our103rd technical video! In this video, Hemant Urdhwareshe explains and illustrates procedure to perform Weibull Analysis of right Censored data (or suspensions) using a free open-source software ‘Reliability Analytics Toolkit’. Hemant is a Fellow of ASQ and is certified by ASQ as CRE, Six Sigma Master Black Belt, CQE and CMQ/OE. This will help viewers to understand how to perform Weibull Analysis of incomplete right censored data without investing in expensive software.

Dear friends, I am releasing this 102nd video after a long gap of more than three months! I went through some critical health issues since October-2024! Now that I have recovered fairly well, I have created this interesting video. In this video, I have explained how to perform Weibull Probability Plotting and life data analysis of complete data using ‘Reliability Analytics Toolkit’.

Dear friends, we are happy to release our 99th technical video on Binary Logistic Regression (BNR)! BNR is an important statistical technique which helps in determining the effect of variable factors on a discrete binary response! Some application examples can be:
• Effect of pouring temperature, pouring time, carbon equivalent on casting defects such as porosity
• Effect of salary, and experience on attrition
• Bankruptcy prediction based on financial ratios.
Hemnat Urdhwareshe, Fellow ASQ, have explained the mathematical basis of the technique and illustrated the technique with an application example on SigmaXL software. We hope you find the video interesting and useful!

Dear friends, many of the viewers had requested for an introductory video on measurement systems analysis (MSA) and Gauge Repeatability and Reproducibility (R&R) Study. We are happy to release this video on MSA! In this video, Hemant Urdhwareshe, Fellow of American Society for Quality, and ASQ Certified Six Sigma Master Black Belt, explains the terminology of measurement systems and also illustrates how to conduct, analyse and interpret the results of a Gauge R&R Study. Hemant has illustrated this with an application example using template from SigmaXL software. Your feedback on the video is welcome!

Dear friends, we are very happy to release this video on the first day of the World Quality Month 2023! Some of you have asked the question about how the formula for success run theorem was derived! You should find answer to that question in this video!
Also, the previous video shows the sample size calculation using template! However, in this video, Hemant Urdhwareshe, Fellow of ASQ, explains the mathematics of it and also illustrates how to perform sample size calculations using Microsoft Excel!

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.
