If you prefer to listen rather than read, this blog is available as a podcast here. Or if you want to listen to just this post: Or download the MP3 I heard a story recently about 3M (h/t: frequent commenter Boonton). Supposedly, back during the SARS outbreak they decided they should build in some “surge capacity” around the construction of N95 masks. Enough additional capacity that they could double their production at a moment's notice. It was unclear if they actually did that or if they were just thinking about it. And even if they had, it appears that the scope of the current crisis is great enough that it’s not as if this one decision would have dramatically altered the outcome. Still it’s hard to dispute that it would have helped.
