GPASS (General Practice Administration System for Scotland)

What are the expected capabilities of a GPAS in 2026? (or are they called practice management systems now?)

More specifically, what is the minimum that is needed for a GP practice.
Also what is desirable/‘nice to have’ - but you don’t always get in modern GPAS ?

I suppose the answers depend on the type of practice - from small to large, rural/remote to city, and other dimentions.

(Please excuse my ignorance - most of my work has been acute hospital systems )
