By applying an enhanced approach, a greater understanding of the methods used in a shorter amount of time can be obtained. Kimber Barnett from Pfizer discusses if using an enhanced (or Quality-by-Design) approach to chromatographic method development revealed the severity of effect of any specific method parameter that may have been missed if another approach was taken.
