Plan - Do a small sketch, write out the signal flow or have a chat with someone about how everything connects. The best way to solve problems is to stop them from happening and if you have a plan in place (and some paperwork to follow) things will go a lot smoother and most simple problems like things being plugged into the wrong spot will be avoided. This is also the best time to be familiar with the equipment you are using, read the user manual (RTFM).
Work systematically - Within your plan think about how you will do things and in what order (not just everything to be done). Common setup issues are ‘high imedance air gaps’ (something not plugged in at all) and are easily avoided when working methodically and systematically. Start at 1 end of the chain and work across, or 1 area of the venue at a time. Communicate that work plan with the rest of your team and stick to it. Jumping between tasks means things get missed, forgotten or assumed.
Test before tricky Installations - if you have some technology elements that are going in hard to reach positions or complex systems test them locally first, confirm they work and do everything required before installation to avoid doing the work twice.

Undo the last thing you just did? Did that fix it?
Has someone else touched something? plugged something into the same switch or power outlet or helpfully ‘removed a random cable’? If so - tell them to undo it and try something else

Check for loose physical connections (especially network cable broken plastic clips?)
Think through the order of operations, are you sometimes doing things in a certain way (when it works) and sometimes a different way (when it doesn’t)
