It just occurred to me that with those massive system files people use we’re basically reinventing expert systems of the past. Time is a flat circle, I suppose.
A decision tree is simply a model where you follow branches and make a decision at each point. Like...

if toaster toasts the bread:
if no: has turning it off and on again worked?
if yes: great! you found a solution
if no: hmm, try ...
if yes:
is the bread burnt after?
if no: sounds like your toaster is fine!
if yes: have you tried adjusting the darkness knob?
if no: ship it in for repair
if yes: try replacing the timer. does that help?
if no: ship it in for repair
if yes: yay you're toaster is fixed
