"Knowing how something works is - very obviously - not the same as being able to repair it"
But it certainly helps to know what a job involves when you have to get someone else to do it. I can do many repair jobs on a car but some are out of reach because of specialist tools or lack of manuals. But I can make a much more informed decision, when choosing someone to do the job for me, if I know how it all works in the first place.
