Origin of Six Sigma Manufacturing

Six Sigma is a manufacturing process control strategy which first implemented by Motorola.

Six sigma being common used by any sectors of industry nowadays, especially those precision product manufacturing.

Six Sigma manufacturing implemented to control the process or stabilize the process. Then, seeks to improve the quality of process outputs.

To stable or improve the process, six sigma manufacturing tools need to be used to achieve the target.

Six sigma tools 

 

Six sigma manufacturing tools is to help organization move toward six sigma qualified process. To achieve six sigma qualify process, six sigma tools - measurement system analytics (MSA), T-test, sources of variation (SOV), statistical process control (SPC) and design of experiments (DOE) are playing important roles. Therefore, understand the function of each six sigma tools are very important.
  • Measurement System Analysis (MSA) is to evaluate the variation on the measurement system to ensure the quality data used for analysis. MSA is to reduce or avoid the variation occur due to the reproducibility (person, procedure, environment or work piece error) and repeatability (instrument and standard error).
  • T-Test is a six sigma comparative method. T-test show the confident interval of the process. T-test including one sample T-Test, two sample T-test and multi sample t-test. And all type of T-test can be either one side or two side T-test. T-test is the tools help on make decision by showing the confident interval which is sigma.
  • Sources of variation (SOV) is a six sigma tool that used to reduce the variability of key process characteristics or parameters (e.g. process outputs, responses). Reduce the variability directly reduce the cost and improve on the process.
  • Statistical process control (SPC) is a six sigma process stability controller and estimator. SPC used for monitoring the process, estimate the abnormality. It gives signal once found any possibility that the abnormality going to happen. So that, the preventive action can be carried out before the problem.

  • Design of experiments (DOE) is a six sigma tool that help in process optimization. Design of experiments also called as Taguchi experiments which is created by Dr.Taguchi.
  • Six sigma tools in excel format is a six sigma tools that customized by using excel. It help to generate the value of sigma level, process capability(Cpk), probablity (P) and defect parts per million (dppm or ppm)
