Knowledge dissemination, as part of the knowledge exchange process, is particularly challenging in any project environment due to the temporary nature of projects. Although several studies in the earlier literature studied the factors that influence knowledge exchange, very few examined them from the ‘knowledge push’ perspective. This study aims, therefore, to highlight the critical factors that impact knowledge dissemination in a project environment. This empirical research found ten critical factors, such as individual experience, trust, source credibility, shared understanding, motivation, and articulability. These individual factors seem to have a dominant influence on knowledge dissemination from the view point of the knowledge source.
