Vantaggi
Pay, benefits, learnings, and opportunities for promotion. (But you have to put in the work and details for these in your promo doc)
Svantaggi
Great until your org starts to make cuts: reorgs/rifs just pile more work on the teams that survive and then you start to see the slackers do bare minimum, some of them will focus all their efforts on job-hopping. (these efforts would've been reserved for project hours improving team efficiency etc) Off shoring: Amazon is more than willing to tell your teams do more with less but then after 2 years of piling more responsibilities on your team, they reward you with lay offs. Then evenly distribute these duties to another region for cheaper labor. Oncalls never end, you will probably develop anxiety for your pager app and the "Sunday Scaries". Dev teams constantly perform bad deployments but never seem to take any lessons learned, even if a COE is created, just constantly increasing burden on SEs.
