light novel takes is the easiest to make and produce quickly. When an anime becomes profitable get a large diverse team of worker to handle various elements of animation. Manga as I have been told is "too many cooks in the kitchen" kind of deal where you cannot speed up the production at the same quality by adding more people. but anime can be sped up by adding more people. you either work like One Piece and stretch 1 chapter to an episode, you work like My Hero Academia and release a season when you have enough manga, or you run a season of anime hope it gets another and then figure out what to do because you normally didn't expect to get this far in the first place.
