A Quality Circle or Quality Control Circle is a group of people from the same area, coming together voluntarily to identify, analyze the work area problems, and find effective solutions. The quality circle members present the solutions to management and implement them after approval. Review and follow-up of implementation are also the responsibility of the […]

Shigeo Shingo of Japan invented the concept called Poka Yoke in the 1960s for preventing human errors. Poka poke is a Japanese term that means Mistake Proofing or Error Proofing. Shigeo differentiated the concepts of human mistakes and defects in the manufacturing process. According to him, “defects occur only when mistakes are permitted to reach the customer”. The essential

MSA stands for Measurement System Analysis. MSA helps to understand the sources of variation that influence the measurement result produced by the measurement system. MSA is one of the very important core tools of the IATF 16949:2016 standard and widely used in Statistical Process Control and problem-solving tools like 8D, and Six Sigma-DMAIC methodologies. The

Accuracy definition: It is defined as how close the measured value to the target/true/reference value. Decisions can be made highly effective if the measurement data have high accuracy and precision. High accuracy and precision in the measurement data can be achieved only if there will be small variations in the measurement system. Instrument/gage with high

Accuracy and Precision are the two important term that often comes into picture during the measurement, testing, and calibration process. The effectiveness of the decisions is based on the measurement data’s accuracy and precision. Equipment with high accuracy and high precision will always lead to better decisions, improve quality of measurement data, low variations, and

Gage R & R (gage repeatability and reproducibility) is the combined estimate of measurement system repeatability and reproducibility. Gage R&R study determines that whether the measurement system is acceptable or not. In measurement system analysis, GRR study primarily focus on two types of measurement system variations – Repeatability and Reproducibility. Both these variations are often

The measurement system variation is also known as a measurement system error. The measurement variation represents the amount of measurement error. Measurement system variation or errors are classified into 5 categories: Repeatability(Equipment Variation) Reproducibility(Appraiser Variation) Bias Stability or Drift Linearity Measurement system variation | Focus Measurement system variations mainly focus on two important factors –
