Pros
I'm in a NAMR Knowledge Team so take that with a grain. Fantastic team manager, really dedicated to building up offerings and has a clear pathway forward. Fun to work with. Work is very flexible, most teams are supporting of hybrid and making room for life stuff in the workday. Work Life balance is great. Content is interesting to develop, case work can be tough some times, but KT has the ability to set clear boundaries, compared to consultants.
Cons
Others have said it before, but the opportunities for career advancement in Knowledge Teams feel out of one's control. You need to collect "feedback" from case teams, who don't really understand your role and see you as an underperformer, because you aren't working insane hours like them. You don't really get to "choose" what cases you work on, so its a toss up if you get noticed by someone worthwhile. People who are higher up often come in at their level, or have miraculously gotten noticed by some MDP, who gave them a good review. I'm sure its possible, but I don't know many people who have gotten more than one promo here. Also, there's no shot of becoming a consultant. You could be "Client Focused" in KT and work 2x the hours for half a consultant's pay if you want.
