A bit of a background to add context.
I’m the asset and content manager of a fair size Indy group and my job breaks down to finding ways and means and most times involves the very questions you asked.and most times code takes care of it’s own problems as by it’s nature the “process” is already structured. Content or game art is a different animal is it’s a process based on iteration of an object that serves a purpose where the problems are not rooted in the building of the object but what to do with it once it reaches some form of usability
The simple solution on our part was to first give the artist a “safe” place to more or less play where they can become part of the solution building as a team rather than dealing with individual needs as being unique and in such a place could create their own productive environment that just works with out the conversion of how it should work.
Not really a new idea but one we stole from the “Valve Employee Handbook” and modified for our needs. Easy to find on Google and a worthwhile read.
I could go on but simple question leads into more complex answers as to practical application but to get our team jumped started I did up two “how to” videos, once I found the safe place to put their work, and from there build up the team where problems is solve with in the team
Sorry if they are a bit short but these are internal videos with the idea of creating a team based environment project and intended to feature out the problems rather than trying to solve them but it does work as a good start
