I begun processing slides without any previous processing experience (not even a B&W roll). It worked, so it should not be difficult.
I have a Jobo CPP-2 which takes care of temperature and agitation. With such a machine, everything is very easy.
Without a machine you have to find a way to keep temperature constant for around 7' and you have to device an agitation strategy that is perfectly repeatable. Some people develop slides without any special apparatus and they refer satisfaction with the results.
The other baths are easy because they are "to completion" and so if your baths are a few °C less than they should you just prolong the bath.
