As early as Aristotle various models of the story have been proposed. Each can be useful if you use it to stimulate your imagination. Each can be harmful if you let it restrict your imagination.
Each of us comes up with our own model of the story tailored to our needs. It is useful to us but maybe not be to anyone else.

My model has five parts.

Each of the parts of the story effects all of the others. This can be expressed by the following diagram. The lines between parts indicate that each part affects every other part, and in turn is affected by that part.
Each part is equally important to the story. But you may use different numbers of words on it.
The space-time part, the setting, may need few words if the story is contemporary. Most of our readers know this arena well. For a scene you need only say something little more detailed than "She jumped into her Ferrari and dashed to her office, nearly running several red lights."
The most words may be spent on the plot, the main character's struggle to achieve hi/r goal. Especially if the story is long. S/he may encounter many obstacles between hi/r and hi/r goal, and several kinds of them: physical, emotional, mental, and social. S/he may have to make several attempts to conquer or bypass each before s/he succeeds.
