I am not a native speaker, so this definitely might not even be a proper word :). Some discussion about it here: https://english.stackexchange.com/questions/396140/is-there-...
In native English business circles, it's a word that someone made up so that they could say "what are our learnings" instead of "what did we learn". Why? To sound more sophisticated and pretentious - or so I suspect.
Anyway, yeah. People use it, even native speakers, even though the word should be taken out and shot.
