sqlserverDBA2016 (10/25/2016)
in general , do most of dbas always install ssas and ssis and ssrs when installing sql server 2014
I can't speak for others but I install everything, no matter which environment, and then disable services that I'm not using so that I don't have to bother with the "WE MUST HAVE <<insert feature name here>> INSTALLED RIGHT AWAY!". It also makes automated installs easy and homogenous except for which features to turn off, which is also easy.
