What exactly do YOU mean by "control?" Some folks are obsessive in "control" and think EVERY sheet of paper or electronic record needs the same security as a top secret "eyes only" document in a spy agency. In most organizations, however, control is merely a routine to assure documents are "managed" to assure they are
- created,
- approved (primarily to check for accuracy and applicability),
- held safely (to keep from loss or destruction, primarily, and secondarily, that those which require extra security, like trade secrets, are kept from unauthorized view.)
- "held safely" also implies measures to prevent unauthorized changes to the documents (records are merely a subset of all documents)
- stored in a manner which facilitates retrieval when required, which includes a method to assure only the most recent or most pertinent version of versioned documents is retrieved - some call this "Configuration Management"
- given a retention period (which is reviewed at the expiration to determine whether the document should be retained in an active file, moved to an archive file, or destroyed (not to be confused with "disposed" - a whole other argument))
In the list provided by the OP, some items "might" be considered trade secrets in one organization (sales figures, number of defective units in WIP) and touted publicly in another , depending on the mindset of the managers and owners. Certainly NOT a decision by a third party auditor.
For the definition of "control" as far as documents are concerned, lets look at the standard.
Documents REQUIRED by the quality management system shall be controlled.
Simple enough?
Then the standard goes on to say that the organization must have a documented procedure on how they will control documents.
a) to approve for adequancy prior to issue,
b) to review and update as necessary and re-approve documents,
c) to ensure that changes and the CURRENT REVISION STATUS of documents is identified,
d) to ensure that relevant versions of applicable documents are AVAILABLE AT POINTS OF USE,
e) to ensure that documents remain legible and readily identifiable,
f) to ensure documents of external origin determined by the organization to be necessary for the planning and operation of the quality management system are identified and their distribution controlled, and
g) to prevent the UNINTENDED USE of OBSOLETE documents, and to apply suitable identification to them if they are retained for any purpose.
Back to that opening line "Documents REQUIRED by the quality management system shall be controlled".
If it is found in use, and it pertains to the quality management system, isn't that prima facia evidence that they have determined that it is needed?
Most of the things listed by the OP look like they are likely in that catagory.
