Although a thorough validation cannot rule out all potential problems, the process of method development and validation would address the most common ones. Examples of typical problems that can be minimized or avoided include interferences that coelute with the analyte in liquid chromatography (LC), a particular type of column that no longer produces the separation needed because the supplier of the column has changed the manufacturing process, an assay method that is unable to achieve the same detection limit after a few weeks, or a quality assurance audit of a validation report that finds no documentation on how the validation was performed.
