The aim of this diploma thesis is to apply the expectation confirmation theory through a modified IS Continuance model according to Bhatacherjee et al. (2008) as an approach to maximise the use of a newly deployed process management application in a business organization. Before application, the theoretical model is validated through a questionnaire survey in the organization that implemented the new information system. Evaluation of the model using the PLS-SEM algorithm revealed low predictive power of the continuance behavior variable and problems in the perceived behavioral control construct (PBC). One possible cause identified in the discussion is the adoption of metrics measuring each construct from the original research, the context of which differed in some aspects. However, the modified model without the PBC construct and continuance behavior variable is valid and statistically significant, and has therefore been used as input to the DMAIC improvement cycle. The improvement cycle is used to achieve incremental improvements in application usage by acting on critical factors leading to the intention to continue the use of the information system by its users.
