This preliminary study describes a baseline State Transition Model (STM) of the personal motivation process, which should be extended for monitoring and controlling the Personal Software Process (PSP) training course. First, we present an approach for formalizing the motivation process when introducing a business method into an organization. The baseline STM is then discussed for three kinds of PSP course at the Kyushu Institute of Technology, where a stable state indicates successful or unsuccessful completion of a course and thus an unstable state is one of the main risk factors for the course. Various characteristics of trainees are clarified to extend the baseline STM.
