When a process is capable, the process spread is smaller than the specification spread. Minitab is a popular tool that allows one to perform various statistical calculations such as normality test, process capability analysis and so on. Let’s discuss about the same in this post. The analysis can also indicate whether your process is centered and on target. This topic has 3 replies, 3 voices, and was last updated 13 years, 6 months ago by Shereen Mosallam. Minitab compares the specification spread to the process spread to determine your process capability. 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. My plant is measuring a length dimension that has a MAX tolerance (2.5mm MAX). Process capability analysis is a major concept and a must study for professionals looking forward having a firm knowledge on Minitab with Statistics. Our customer is requesting capability data, but my plant is unclear if minitab is able to run capability. 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. ![]() ![]() The target is the ideal value of a process based. To satisfy customer requirements, the thread length of the bolts should be within 0.1 mm of the target of 20 mm. ![]() 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.
