Explanation

Cp and Cpk are statistical process control indices used in quality management to evaluate how well a process performs relative to its specification limits. Cp measures overall process spread (whether the process fits within tolerances), while Cpk adds centering - it accounts for where the process mean sits relative to those limits, making it a more complete capability measure. Options A, C, and D are wrong because these indices are purely statistical tools tied to manufacturing or process variation; they have no connection to employee reviews, marketing effectiveness, or financial metrics.

Memory tip: Think "Cp = Process capability, Cpk = capability with a knee toward the nearest limit" - both live entirely in the world of spec limits and process variation.
