The capability index is a statistical measure used to assess how well a given process conforms to its specified limits. It typically focuses on evaluating the performance of a process in terms of its output consistency, variations within the established limits, and compliance with specifications.

When considering what is typically monitored, employee motivation levels stand apart from these metrics. Capability indices like Cp, Cpk, Pp, and Ppk are quantitative tools that analyze process performance and variability but do not directly assess or monitor qualitative factors like employee motivation. While employee engagement and morale can have indirect effects on process performance, they are not measurable by the capability index and are typically evaluated through different methods such as surveys or interviews. Thus, it's clear that employee motivation is not relevant when assessing process capability.
