The document presents a new theoretical model of employee engagement drawing from models of work motivation. It defines two forms of engagement: task engagement, which is short-term motivation directed at completing tasks; and job engagement, which is an ongoing motivational state directed at sustaining job performance. The model proposes that job engagement is influenced by an individual's goal commitment to job performance, their belief in their ability to complete tasks, motivation to complete tasks, and evaluation of whether tasks were completed. It is also influenced by environmental enablers like leadership, resources, and training. The model aims to integrate insights from motivation research to provide a useful definition and conceptualization of employee engagement.
