Troubleshooting is time consuming. Sometimes the problem is obscure and hard to research but most of the time the issue becomes apparent early on in the process. One by one this troubleshooting methodology isn’t a huge time commitment, however as more break fix problems creep up it can consume more time than one realizes. I liken it to working a jigsaw puzzle. When you sit down to put the puzzle together you flip all the pieces over and sort them to make the problem easier.
