New Producers: What are the biggest Calendar/Doc/Version Control pitfalls to watch out for?

Hey everyone,

Sarah Chen here. As a working Cinematographer, I've seen a lot of productions, and thinking back to my own early days, I definitely made some workflow mistakes that caused headaches for others (and me!). Now, I often find myself chatting with newer producers who are just getting their feet wet, and I want to offer them solid, actionable advice.

My question for this seasoned community is: What are the most common and damaging pitfalls you've witnessed new producers fall into concerning Calendars, Shared Documents, or Version Control? I'm talking about the kind of errors that really gum up the works. And, more importantly, what's your top piece of practical advice to help them proactively avoid these issues?

Looking forward to hearing your insights!
