The Scene is the basic building block of a story. A Scene has two parts: the action part and the reaction part.
The action half of a scene consists of a goal, conflict, and disaster.
The goal of a scene is usually a small piece of the overall plot goal or it can be a major piece of the plot goal. The goal of a scene must make sense in the overall plot of the story. It cannot be something random just to add something interesting to your story. It must move the plot forward. The goal of the scene has the PoV character (generally the protagonist) trying to obtain or avoid something physical, emotional, or mental. The goal must directly affect the PoV character, if it doesn’t you may what to switch to a character who has a higher stake in the scene. The goal should also lead to a new scene.
The conflict within a scene must flow from the goal. It should be about something that matters to the PoV and threaten the PoV’s ability to achieve the goal. It must be logical or your reader will not be able to remain in the story. Not every scene has to be a major battle. It can be something small that gets in the way of what the character wants.
The disaster should answer the question driven by the goal of the scene and prompt a new goal for the next scene. It needs to be flow logically from the goal and conflict. The disaster needs to raise the stakes, but not be melodramatic.
For example if your protagonist has a goal to obtain information from another character. The question is will he get the information. The conflict could be a million things but for this example, it is that the character with the information is intoxicated and doesn’t make any sense. The disaster is the protagonist never getting the information he needed because the character dies in a car accident on the way home.
The reaction half of a scene consists of reaction, dilemma, and decision. The reaction half can be very short, just a couple sentences, or it can be much longer. At times, it is interlaced within the action.
The reaction needs to correlate to the proceeding disaster. The reaction must make sense in the context of the story and be true to the PoV character’s personality. Reactions are important because they create the bond between the character and the reader. Don’t skimp on the reaction half of scenes.
The dilemma of the reaction portion is where the character reviews what happened, analyzes it, and plans his/her next step. The disaster of the action part of the scene influences the dilemma of the reaction portion. Be as clear and specific as called for in the story.
The Decision must be an organic result from the dilemma. It also needs to lead to a strong goal for the next scene and advance the plot. As will every piece of the scene it must be an important logical step in the plot of the story.
All the scenes of a story should line up like dominos. Each triggering the next in the line.
