Why Quick Error Review Is Often Skipped
Engineers often avoid a quick error review because building a new feature feels more active and rewarding than checking whether the idea is actually promising. That hesitation can be expensive: a short manual review of, say, 80 mistakes at about 90 seconds each takes only around two hours, yet it can prevent many days or weeks of work on a fix that would not help much.
