It enables you perform process capability analysis on non-normal processes without undue math anxiety an evaluation version of this software can be downloaded from the symphony technologies process capability evaluation.

Process capability compares the output of an in-control process to the specification limits by using capability indices the comparison is made by forming the ratio of the spread between the process specifications (the specification width) to the spread of the process values, as measured by 6. Process capability analysis using minitab (ii) by keith m bower, ms abstract this paper builds on the content covered in the previous edition of extraordinary. What is capability process capability compares the output of an in-control process to the specification limits the comparison is made by forming the ratio of the. 4 process capability the ability of a process to meet product design/technical specifications conducted only when the process is normally distributed.
