The purpose of this study is to present a conceptual process model of the consumer complaint behavior (CCB) in sport management. An effective process model of the CCB will contribute to the analysis and description of a post-purchase consumer behavior and the formulation of a defensive marketing strategy. The procedures of the study are as follows: (1) the first step provides a review of the previous study on CCB model such as Gronhaug's (1977) conceptual model of consumer complaining behavior, Andreasen's (1977) model of postupurchase consumer process, Day's (1977) post evaluation behavior model, Day and Landon's (1977) flowchart of consumer's postdissatisfaction decision process, Kojima's (1980) descriptive model of CCB, and Kashiwagi's (1985) model of post-purchase consumer behavior. The necessary perspectives and hypothetical constructs to build the CCB model in sport management are deduced from these CCB models: (2) In the second step, a conceptual process model of CCB in sport management is presented. A reasonable approach that breaks the process down into three major components is used to build the CCB model in sport management. These components include "marketing factors controlled or primarily influenced by marketers", "consumer factors", and "circumstantial/environmental factors that are independent of the marketing and consumer factors": (3) At last, each phase of this conceptual process model in sport management is described and discussed .
