A social constructivist orientation is used in conjunction with an adapted form of Leavitt’s (1965) organisational change model in order to deconstruct individual stakeholder perceptions and experiences. The research reveals that stakeholders perceived and experienced the implementation differently - based on their construction of individual and organisational reality. The research suggests that the success of an IS implementation may be enhanced if IS practitioners recognise the significant influence of constructed individual and organisational reality on the progression of an IS implementation, and the consequent impact on organisational performanceenChange managementInformation systems implementationThesis
