Ryoko did a storyboard for Theo as means to get the Head Director position but after the storyboard process, there are the layout procedures.
This process is less well-known but equally important to the other processes, which marks the beginning of art production.
In simple terms, developing a layout is about positioning the cels that will be used in the cut and the background art that will be needed, giving the definitive blueprint for how the final shot will look.
The cuts are drawn up to the same size as the animation paper and the details of cel placement, precise descriptions of camera movement, and other decisions are included.
In collaboration with the director, and possibly producers, the senior animators draw the layouts (or sometimes the staff is specifically credited with layout drawings) and the shots are called about where the cels/characters are going to be situated and the way a cut is going to be framed.
