In recent years, the field of human resource management has entered a period of major change, from a system based on seniority to that based on merit, and then, from a system based on merit to that based on performance. It appears that severe tensions have arisen because the conventional system cannot accommodate the activities of employees wishing to respond flexibly to the changes in the market and the expectations of management groups. However, we can occasionally observe cases where, despite the spectacular reforms implemented, a number of enterprises have not sufficiently achieved a feeling of success, and they are fighting a difficult battle. We believe the most reliable means of opening a new style of human resource management in the 21st century can be found from the worksite. In other words, the shortest path to management reform is to create a vivid, realistic picture of human resource management at the worksite, to extract the elements of the picture one by one and to use the results to improve performance. Based upon the idea of worksite-oriented philosophy, JMAC provides support under its commitment to providing consulting services consistently and earnestly. - Reform of personnel system - Human resource development management - Personnel evaluation/assessment - Activation of the organization - Right sizing of personnel - Organizational climate diagnosis - Training for managers - Development of problem solving/communication ability - Employee Satisfaction (ES) improvement - Development of core human resources for management
