The major components of a pre-production process are as follows: 

1. Storyboarding 

2. Layouts 

3. Model Sheets 

4. Animatics

1. Storyboard: The storyboard helps to finalize the development of the storyline, and is an essential stage of the animation process. It is made up of drawings in the form of a comic strip, and is used to both help visualize the animation and to communicate ideas clearly. Storyboards often include notes to describe the frame in more detail, such as mood and lighting, as well as camera moves. 

2. Layout: Once the storyboards have been approved, they are sent to the layout department which then works closely with the director to design the locations and costumes. With this, they begin to stage the scenes, showing the various characters' positions throughout the course of each shot.

3. Model sheet: Model sheets are precisely drawn groups of pictures that show all of the possible expressions that a character can make, and all of the many different poses that they could adopt. These sheets are created in order to both accurately maintain character detail and to keep the designs of the characters uniform whilst different animators are working on them across several shots. 

4. Animatics: Ananimatic is a timed moving version of the storyboard made up of individual frames taken from the storyboard and is often accompanied by audio such as dialogue, sound effects and music. Each frame of the animatic depicts a certain key point of the scene or movie. The running time should match the intended running time of the final animation.
