It outlines approaches such as one-factor-at-a-time and simplex optimization to find optimal responses.

Verifying a method, as described in the previous section, establishes this goal for a single analyst. Another requirement for a useful analytical method is that an analyst should obtain the same result from day to day, and different labs should obtain the same result when analyzing the same sample. The process by which we approve method for general use is known as validation.

Quality assessment helps maintain, detect, and suggest solutions for loss of statistical control. It includes internal methods, like analyzing duplicate samples and spikes, and external methods, such as laboratory certification by an agency.

Verifying a method, as described in the previous section, establishes this goal for a single analyst. The process by which we approve a method for general use is known as validation and it involves a collaborative test of the method by analysts in several laboratories.
