A capability analysis is fundamentally focused on understanding how well a process can produce outputs that meet specified requirements or specifications. This is typically achieved by comparing the performance metrics derived from the process, such as process mean and variability, against the established specification limits set by customer requirements or industry standards.

When conducting a capability analysis, key metrics such as Cp, Cpk, Pp, and Ppk are calculated. These metrics provide insights into how well the current process can perform relative to these limits, informing whether the process is capable of producing products that consistently meet customer expectations.

Assessing equipment efficiency, evaluating employee productivity, or reviewing financial statements do not directly relate to the capability of a process regarding its output. While these aspects might influence overall performance indirectly, they do not form the basis of a capability analysis, which is strictly concerned with measuring the ability of a process to produce items within specification. Thus, the most relevant and accurate choice for performing a capability analysis is the comparison of performance metrics to specification limits.
