The first formal document you create in the script writing process is called a concept. Whatever you call it, concept or outline, its function is the same, namely, to set down in writing the key ideas and vision of the program. This document is written in conventional prose. There is no special format for it. It does not cover all the plat or content; nor does it include dialogue or voice narration. It is primarily an idea in a nutshell from which the script in all its detail will grow.
