Abstract
In the recent research into the project management of human factor, the motivation content theories such as Herzberg's motivation-hygiene theory are applied. The motivation theories include the process theory other than the above-mentioned content theory. In this research, I investigate human factor by applying Lawler's expectancy theory model. In this paper, as an example case, I used three-step questionnaires in "company A" which introduced the CCPM(Critical Chain Project Management) method successfully. I analyzed it by applying the model to the responses to the questionnaires. This analysis has proved that the project members were more motivated when their goals were achieved by introducing the CCPM method. We discuss this motivational process by applying Lawler's expectancy theory model.
