That can be semi-formal logic if it's stated as a given rule-of-thumb. Most of the time your debate partner(s) will agree with such rules of thumb, barring some odd edge case. If an edge case is allegedly in play for the context, that path is then explored in more detail.
In IT, often rules of thumb will conflict, such as "a stitch in time saves 9" versus "keep it simple" (YAGNI). In such cases I often use labor hours and finance-like decision making techniques, not unlike deciding on insurance: what are the monthly premiums (ongoing costs), how likely is the targeted/prevented event to happen, and what's the cost of not having the prevention or preparation in place. It's not a perfect model, but at least is a numeric framework to discuss with rather then "I feel that...". Probabilities and money (labor hours).
A lot of what people call logic are things like "not expecting a different result from the same behavior" and "not follow an impulse with no relation to reality" but even those are heuristics. Usually good heuristics but not logic.
