This is happening in two phases.
Phase 1 - SAs will be in Click 2 Expert and AMs will engage you that way. It will be told to you that this is for metrics only. (There is a hidden agenda by EK and SEDs.)
Phase 2 is full Agile TSA. This is to reduce cost per head. The question you need to ask your SEM and SED is if there an initiative to reduce the cost of pre-sales engineering. Why are they not hiring or backfilling many of the SA positions.
SAs will be assigned a couple of solutions that they will focus on. No more development or career paths.
Go ahead and ask your SEM and SED.
EK and SEDs are getting pay increases while they reduce number of SAs.
