Hey @Amanda.Schade,
this forum post summarizes several similar questions and answers that I am aware of for at least 8 years. I think that a stream talking about game project which covers the amount of expected team members (with their roles) and expected knowledge each one should have. It would be gold that info for all the newcomers to the engine which might be or not already in the game industry, even more coming from an experienced company as Epic.
Just a thought
