# Capability indicators
To access the capability indicators, open "descriptive statistic/details" and enter the min and max tolerances for your production.

In order to appreciate the capacity of a production process to produce good parts, i.e. within the tolerance interval set during conception, we calculate the process capability indicators. 

![capabilite](baseUrl/statsDescriptives/capabilite/capabilite.png)


The process capability is defined by:

![equation](Cp="IT"/"dispersion")



Within the context of normal distribution we consequently have ![equationInline]("dispersion=6*sigma), therefore:

![equation](Cp="IT"/(6*sigma))
