Hmmm. I think the checklist exists, for sure, but tends to be more Plan B. If your initial strategy is exhausted with no progress, fall back on the checklist.

As a programmer I have an opportunity not everyone else has. I can codify parts of my checklist in a way where I don't really have to think about them at all save for a few times a year with the big outlier problems, teaching someone to do basic troubleshooting themselves, or starting a new project.
