First, SSMS 2016 is now based on the Visual Studio 2015 Isolated Shell. SSMS has a number of core changes compared to earlier versions of SSMS.

Separating the SSMS installation from the main SQL Server Installation Center makes it easier to install SSMS on a separate systems. In addition, a best practice for managing SQL Server is to run SSMS from a networked workstation rather than running SSMS directly on the SQL Server system itself. First, this allows Microsoft to update SSMS more frequently than they were able to in the past when it was bundled in with the main release. There a number of reasons Microsoft has made this change. Instead you need to install SSMS separately. Now SSMS is not installed as a part of the main SQL Server installation process. That is no longer the case with SQL Server 2016.

In previous releases SSMS was installed as a part of the SQL Server installation itself from the SQL Server Installation Center. With the SQL Server 2016 release Microsoft has changed the way that they are delivering SQL Server Management Studio (SSMS).
