I have just published some notes on “side friction”, which you can download (for example) from Academia. The document has a “discussion” section which in part looks at how current design standards fail their users. Examples of these failures include inconsistent terminology and lack of traceability.
Another one, which I plan to add to the next version of the document, is “findability“, in the sense of “is the information I am looking for, easy to find?” To take two examples, in a Tanzanian standard (ref. 294) the information is easy to find, whereas in the USA’s AASHTO document (ref.831) it is not so easy to find.
Of course, it does not follow that, even if the information is easy to find, the information is correct.
