WebAbstract: In the paper , a process capability and process performance analyse s for continuous and attribute data are conducted by using an industry example. The inner diameter of the bearing rings is analysed by applying the normal capability analysis for the continuous data and byapplying the binomial capability analysis for the attribute data. WebA weakness in capability estimates for attributes data is that they do not suggest why a system is either capable or not. For instance, there is no way of knowing whether the system is incapable because it is not centered, it is too close to a specification limit , or it exhibits too much unit-to-unit variation .
