I believe it would help if you go back and read section 8.3 of ISO 9001:2015.
Ask yourself the following question:
Does this document/record show objective evidence of meeting the requirements in the standard?
If the answer is no: You do not need to control or manage that document/record.
(Example: An engineering is tinkering and makes a drawing, but there is no customer involved, and the drawing most likely will not turn into a product. This would not have to be controlled.)
If the answer is yes, the document does show objective evidence, ask yourself another question: Will this document/record be used to create another higher level document that contains the exact same information? (Example: someone made a calculation sheet that will then be copied into a larger data set. The small calculation sheet does not have to be controlled.)
If the answer to the last question is no, there is no higher level document that contains all relevant information: You must retain and control that documented information.
I hope that helps.
