Written Procedures

Instructions written in advance for how production and process control are to be carried out, approved by the appropriate organisational unit and by the quality control unit.

Source · 21 CFR 211.100 Written procedures; deviations, (a)–(b)

Details

This is the phrase that appears most often in United States findings, cited in two forms: the procedure was never established, and the procedure existed but was not followed. Real cases include no cleaning or equipment maintenance procedure, revisions that did not go through approval by the appropriate unit and the quality control unit, and records written up later in a batch rather than at the time of performance. Because 211.100(b) requires any deviation from the procedure to be recorded and justified, check the approval block and the copy available at the point of work together with the justification records for departures from it.
