We all know that software has been the focus of Blackberry since the John Chen era began. BES 12 is one of its biggest advantages in that area since it's considered the best choice for cross-platform enterprise mobility management (EMM) solution you can find out there by far.
During the Q&A section at the Fourth Quarter Fiscal 2015 Earnings Conference Call, John Chen states that he wants BES12 to manage all of your devices. He plans to ensure that BES12 will always stay high in the EMM ecosystem, meaning that he's going to give the best out of BES12 for all the smartphone operating systems.
Chen also addressed a question regarding BlackBerry's partnership in EMM solutions with Samsung's Knox which has created confusion since BlackBerry already has BES12. Chen doesn't seem to be bothered by that as he said that it is people's choice whether to go with BES or Knox. Both of them have BlackBerry in it though.
