Absolutely guilty of that! Although the article mainly focuses on software that I also assume isn’t critical, sometimes you have to get the work done perfectly, or it’s a major risk or an overall issue for the project success. For example, if you are designing, building, and programming a drone, the margin for error is slim. A single issue that you are not even directly responsible for can jeopardize the whole project, like if a cellular drone control link (C2) is down. Or you are working on an ICS that controls utilities or nuclear plants. So, you have to perfect all scenarios and outcomes, plus all possible testing too.
