Occam's Razor is a problem-solving principle stating the simplest explanation fitting the evidence is most likely correct. In root-cause analysis, it systematically identifies likely causes by comparing explanatory power and testing the simplest option first.

To identify a bug's root cause, enumerate competing hypotheses and list required assumptions for each. Compare explanatory power and simplicity, then test the hypothesis with the fewest assumptions first to reduce investigation time.

Yes, parsimony-guided decision-making applies to software architecture choices by systematically evaluating competing design hypotheses, comparing their required assumptions, and prioritizing the simplest explanation with the highest explanatory power.

The best way to evaluate competing debugging hypotheses is to list supporting assumptions for each, compare their explanatory power and simplicity, and apply the simplest explanation first, escalating to complex options only with new evidence.

You should escalate beyond the simplest explanation during debugging only when new evidence invalidates the initial hypothesis. Apply the simplest explanation first and escalate to more complex root-cause hypotheses solely when evidence demands it.
