When I ask you about the organization of a novel or organization within a novel, I'm generally referring to one of three types: chronological, spatial, or climactic/importance.
Chronological organization refers to events that occur in order by time (first, second, last).
Spatial organization usually occurs in smaller portions, like description of objects. Organizing objects spatially means that they are grouped by physical relationship.
Grouping by order of importance or climactic organization means that events build upon each other until the climax (high point) is reached.
