The analyst uses a normal capability analysis to evaluate how well the process meets the specifications of 20 ± 0.1 mm, based on a normal distribution of the data. To satisfy customer requirements, the thread length of the bolts should be within 0.1 mm of the target of 20 mm. The target is the ideal value of a process based. Minitab is a popular tool that allows one to perform various statistical calculations such as normality test, process capability analysis and so on. While not exactly showing off my engineering prowess I want to also post videos that can help and inspire others with how-to single-point lessons. Our customer is requesting capability data, but my plant is unclear if minitab is able to run capability. Process capability analysis is a major concept and a must study for professionals looking forward having a firm knowledge on Minitab with Statistics. My plant is measuring a length dimension that has a MAX tolerance (2.5mm MAX). In addition, the analysis estimates the proportion of product that does not meet specifications.įor example, a quality analyst wants to evaluate the capability of a bolt manufacturing process. Minitab compares the specification spread to the process spread to determine your process capability. This topic has 3 replies, 3 voices, and was last updated 13 years, 6 months ago by Shereen Mosallam. The analysis can also indicate whether your process is centered and on target. Let’s discuss about the same in this post. Minitab is a popular tool that allows one to perform various statistical calculations such as normality test, process capability analysis and so on. When a process is capable, the process spread is smaller than the specification spread. Process capability analysis is a major concept and a must study for professionals looking forward having a firm knowledge on Minitab with Statistics.The analysis evaluates the spread of the process data in relation to the specification limits. To perform the analysis, you must specify a lower or upper specification limit (or both) to define your process requirements. Compare the overall capability of the process with its potential (within) capability to assess opportunity for improvement.Determine whether the process is capable of producing output that meets customer requirements.

There are no out-of-control points in the control chart and the P value is greater than 0.05 so we. Using this analysis, you can do the following: Process Capability Sixpack Report for Broom Boom Length. Use Normal Capability Analysis to evaluate the potential (within) and overall capability of your process based on a normal distribution.
