These are questions that are worth delving into more deeply. In my brief period at IBM I was adjacent to the Watson Health folks and the challenge, to my unsophisticated eye, was greed. Basically the "Health Care System" in the US appears to be completely corrupt[1]. Thus any proposed change the is presented based on how it will "Improve the system" is immediately suspect by those for whom the unimproved system is paying them a hefty paycheck. In the two (and be aware there were thousands so this is an anecodtal sized sample set) engagements I had visibility into with Watson Health teams, the one that went in with "This will improve patient outcomes" got shut out, and the one that went in with "This will increase your net margins" was welcomed with open arms.
I'm not sure how one unties that particular knot.
[1] Corruption here being that the primary mission is the collection of monies and health outcomes are a tolerated side effect of that.
