In the first simulation this week, we are requesting changes to documents in the Quality System hierarchy. The hierarchy laid out in this simulation is the Quality Manual on the top, followed by Quality System Procedures (QSP), followed by Work Instructions (WI), followed by the Specification on the lowest level. Many of these documents reference documents at different levels of the hierarchy. For example, the WI may reference the Spec. I want to pose the question, when these documents are referenced in another document, such as the example given, is it necessary to include the revision of the document? What are you thoughts?

My thoughts are that it is not necessary, because then when one document is updated to a new revision, it can create a cascading effect where all the documents that reference the updated document need to be revised as well so that they are not referencing an outdated document.
