In this paper, agent based process management model is proposed, which is for the process management of knowledge worker and service workers in order to establish the basis for the new knowledge management system. In this paper, we applied several methods from 6 sigma and PSP for process definition, process execution, and process measurement. This study attempts to improve the process execution accuracy through process visualization and standardization and to accumulate the base data to improve the process through measuring the process execution. We proposed guidelines and detail procedure for developing 3 advisor agents for guiding the process definition, process execution, and process measurement. And we showed the simple case study applied our guidelines defined in agent.
