The following may be of interest to readers:
An analytical procedure must be demonstrated to be fit for its intended purpose. It is useful to consider the entire lifecycle of an analytical procedure, i.e., its design and development, qualification, and continued verification. The current concepts of validation, verification, and transfer of procedures address portions of the lifecycle but do not consider it holistically. The purpose of this proposed new chapter is to more fully address the entire procedure lifecycle and define concepts that may be useful. This approach is consistent with the concept of quality by design (QbD) as described in International Council for Harmonisation (ICH) Q8-R2, Q9, Q10, and Q11. The lifecycle approach can potentially be applied to all procedures, although the level of effort should be consistent with the complexity and criticality of the procedure.
