The Knapp’s Relational Development Model is a theoretical model to map the progression of an interpersonal relationship between two parties. The Relational Development Model identifies 10 different stages divided into three overlapping phases: coming together, relational maintenance, and coming apart. To better understand what makes relationships work or fall apart, it is important to examine each stage of development not only by itself but also in its role in the movement from one stage to another as the relationship progresses or falls apart. It is important to note that movement is not necessarily progressive. It is possible to jump between the different phases.
