Writing should include a

treatment: a document, usually just a few pages long, that program producers use to communicate a media concept (idea) with all stakeholders, including sponsors and the crew
proposal: a basic idea of the program, an applicable program format, a message imparted to the audience, the program’s intended audience, budget considerations, shooting location considerations, and rough program shooting schedule
pitch: a compelling case for producing the project, which should include
- why it is important
- how it will be effective
- what practical issues (e.g., constraints of time, money, equipment, and personnel) might be needed to successfully produce and distribute the program.

Process/Skill Questions:

What elements should be included in a program treatment?
What other documentation besides a treatment is required by most productions in the pre-production (production planning) stage?
How does a treatment differ from a pitch?
