In recent weeks, IBM has changed leadership at its Watson Health division and announced a new business strategy for deployment that relies on a hybrid cloud, not a public- or private-cloud only model.Over the past year, Watson Health & particularly Watson for Oncology & has come under criticism for not meeting expectations or even offering physician users inaccurate advice.

(Watson for Oncology isIBM's commercial cognitive computing cloud platform that analyzes large volumes of patient healthcare data and published medical studies to offer physicians cancer treatment options.)
