Another model that is related to media richness theory as an alternative, particularly in selecting an appropriate medium, is the social influence model. How we perceive media, in this case to decide where a medium falls on the richness scale, depends on "perceptions of media characteristics that are socially created," reflecting social forces and social norms at play in the current environment and the context that determines the needed use. Each organization is different in the goal that is trying to be reached and the missions that are trying to be completed. Thus, with different organizational cultures and environments, the way each organization perceives a medium is different and as a result, the way each organization uses media and deems media as more or less rich will vary.
