One person should be the lead/BIM coordinator and organize who does what. You also will have to decide about who edits families, shared parameters, keynotes, schedules etc. Are all the people in your company in the same discipline? Or is one doing architectural, electrical, HVAC etc.? For different disciplines it often is better to split the model and link them.
For Keynotes I ended up using Google sheets. I then share the that Google document with who else is supposed to work on keynotes. From that the txt file will be created. This requires discipline and people knowing what they are doing.
If the level of sophistication vary greatly, you may need some different strategies.
I don't know if BIM360 makes any of the above easier. We don't have that, but it may be another tool to help. i have extremely little experience work sharing. So take more advice from the above posts 🙂
