At the Jedi Temple, a capability analysis was run on the length of lightsabers that were being produced. Minitab Statistical Software helped to check if the lightsabers fit within the required length specifications decided by the Jedi Council.
Capability analysis is used to evaluate the potential of an in-control process. The first step to execute a capability analysis is to ensure that the set up of data is appropriate. The measurement data needs to be put in one column of a Minitab worksheet.
Another significant step in capability analysis is recognizing the subgroups. A subgroup is nothing but a group of units generated under the same set of conditions. There are 10 subgroups at the Jedi Temple, having eight units in each subgroup.
During the capability analysis, we must ensure that data are entered in the same sequence it was gathered, and that each entry is placed in the appropriate subgroup. The calculations which are important for the analysis depend on the sequence of the data as well as the size of these groups. Once there is surety of the size of the subgroup and correct entry of data in the Minitab, subgroup columns can be created.
The manner in which the data are entered in the dialog box tells Minitab to display each value for a particular number of times; this represents the number of measurements taken each day, forming the subgroups.
Once the data are set up in Minitab correctly and the subgroups are recognized correctly, the analysis can be performed.
