This research-in-progress paper provides a framework to determine end-users’ intention to use a project plan Decision Support System (DSS) by applying the widely tested Technology Acceptance Model (TAM). The purpose of the framework is to serve as a foundation for collecting and evaluating further empirical evidence of end-users’ acceptance of a DSS. The framework allows the researcher to establish whether the TAM fairly measures end-users’ intention to use a DSS to support the creation of a project plan.The significance of the intended resulting research surveyis to provide further evidence as to whether the TAM can be used in DSS research to measure end-users’ intention to use a particular information technology application that aids management’s decision process.
