This survey investigated the intentions of current users of the project management tools Mural and Trello in the United States. This study focused on small and medium enterprises (SMEs) in the United States. The survey results of 291 employees whose companies had them use either Mural or Trello to coordinate and organize their work were analyzed. Through structural equation modelling (SEM), this study confirmed that the components of effort expectation have direct and meaningful effects in the conceptual model, which in turn affects the staff's actual usage of the Mural and Trello systems. As a bonus, the aspiration to use Mural and Trello in the future affects their actual usage. Moreover, it suggests future research and implementation directions, including the theoretical and practical consideration of technologies in collaboration platform systems.
