A formula, however, is totally different. A formula never varies; certain elements are put together so they come out exactly the same each and every time. If you put that coat on an assembly line, every coat will be exactly the same, with the same pattern, the same fabric, the same color, the same cut, the same material. The coat does not change, except for the size. A screenplay, on the other hand, is unique, a totally individual presentation.
The paradigm is a form, not a formula; it’s what holds the story together. It is the spine, the skeleton. Story determines structure; structure doesn’t determine story.
The dramatic structure of the screenplay may be defined as a linear arrangement of related incidents, episodes, or events leading to a dramatic resolution.
