The establishment of qualification target expectations can be considered as a form of Quality
by Design (QbD), since this methodology establishes quality expectations for the method in
advance of the completion of method development. Also, the analytical lifecycle described
here covers all aspects of method progression, starting with method development, the
establishment of system suitability parameters, and qualification and robustness activities,
culminating in method validation, which confirms that the method is of suitable quality for
testing in Quality laboratories. The entire analytical lifecycle framework can be considered
as a QbD process, consistent with evolving regulatory expectations for pharmaceutical and
biopharmaceutical process and product development.
