As mentioned often "that won't work" is a good way to cut off all creative thought processes and should be limited, but there are definitely times when a quorum of uninformed parties are about to commit to 'an investigation' where someone calling it straight is appreciated

I'd agree with this. The article specifically mentions the need to analyze rather than jump to conclusions, and "That won't work!" is usually a case of the latter. If TWW is the result of an analysis, then it is definitely not what I was referring to in the article.
