The lean consultant usually facilitates the first few kaizen events at an organization. These events lay the groundwork and provide training for the champion, management, and workers, who will assume their future roles as trainers, team leaders, and team members on future events. Once experience has been gained, the consultant assumes more of an advisory and mentoring role, overseeing the events until his or her services are no longer needed. Because the success of kaizen is so important, management usually demands regular updates on the progress. It is a responsibility of the consultant to keep management informed, especially of difficulties, which may alter the outcome of the event. Annually, it is the responsibility of the lean champion to establish plant priorities for lean training and implementation, and to work with the director of continuous improvement and plant manager to establish a TPS training and kaizen event schedule.
