One of the benefit with EA, even for a small company, is that it force you to focus your business priorities.

What is a business need for a film production company? Lets give two rather simple examples.

We need to be able to produce corporate videos for small and medium size organisations faster, and to a lower cost, still maintaining quality. (Production process)
We need to reply fast on request from other production companies to provide crew, and follow up those opportunities with clients. (Sales process)

a third, less important right now, business need is

We need to be able to produce a full length feature faster for a distributor, and to a lower cost, still maintaining quality. Funding is done by investors and with grants. (Production process, HR, Supply-chain, Finance and Workplace, facility and IT)

This third one is very much more complex on several different levels, and we need to break it down into pieces. But this requires deep business knowledge of how to to filmmaking.

EA is much more than IT, and even manual processes can get benefits of a structured approach.
