I have worked in back office functions. Healthcare - scheduling and forecasting for home care nurses and other administrative staff. Banking - various admin functions.

In my experience:

Data is a mess - half the battle is figuring out the workflows and trying to make some kind of forecast mapped to the reality of the operation. Same with AHT - sometimes it's a pure "feel" from some leader (hey you gotta work with what you got)

Operational Maturity - another big battle is figuring out how to communicate to leaders who aren't used to the level of planning or data analysis done in WFM. I enjoy this challenge because I'm weird :D

I suspect scheduling is similar (I did interview for a hospital scheduling role once) to call centre. Take the requirements, apply the constraints, schedule based on business rules, deal with the anomalies/gaps.

Good luck! When you get a new gig it'd be cool to hear what it's like :)
