Microsoft's divisions like Office, Windows, XBOX and Skype have always been separate from one another with not a lot of collaboration with each other. The outgoing CEO has decided to change this. The 'One Microsoft' initiative is said to bring all the divisions of Microsoft closer and build services that collaborate with each other and work together as an ecosystem for greater speed and efficiency. There are already signs of this happening with Windows PCs, Windows Tablets, Windows Phone and XBOX One. And on the hardware front, the introduction of Surface Tablets and the acquisition of Nokia only emphasizes the fact the Microsoft wants to build its own hardware like Apple.
Microsoft is the only company that competes with Apple and Google combined on so many fronts, like on the PCs, Tablets, Phones, Web, Living Room and Enterprise. Microsoft's Ecosystem is broad and it is the only company that has viable products in all these domains. If concerted efforts are in place, Microsoft’s Ecosystem can go a long in becoming the best offering yet.
Microsoft has a very ambitious vision here and it all comes down to the Execution and Implementation. Microsoft has always been criticized for bad execution and a incomplete vision. Now they have a grand vision to take over your TV, PC, Tablet, Phone, Web and your Office, but can they execute it well? All is left to be seen.
