A schematic is a diagram of an object or interface simplified for the sake of clarity. A schematic is defined as a picture that shows something in a simple way, using symbols. A schematic diagram is a picture that represents the components of a process, device, or other object using abstract, often standardised symbols and lines. Schematic diagrams only depict the significant components of a system, though some details in the diagram may also be exaggerated or introduced to facilitate the understanding of the system.
Schematic diagrams do not include details that are not necessary for comprehending the information that the diagram was intended to convey
Schematics are known by many other names including wireframes, sketches, lo-fis, and blueprints.
Since a schematic reduces complexity, unintended errors and ambiguity can be introduced. Would someone understand from the previous schematic to put cheese on top of the tomato sauce? Maybe not.
This is a case where an exploded schematic is useful, because it shows how the individual pieces come together to form the whole.
Schematic diagrams can also differ in their level of abstraction.
