Rapid economic changes have recently been requesting human resource departments in Japanese firms to transform their roles and services. However, Paul et al. state that the focus of work on HRM is oriented towards HRM Policy Choices and short-term HR outcomes in Harvard Model. Therefore, Sato et al. insisted that we need to consider long-term consequences. The goal of this paper is to discover a causal relationship between HR Systems which is HRM Policy Choices and HRM outcomes including short-term HR outcomes and long-term consequences based on the Harvard model, in order to increase HRM outcomes including short-term HR outcomes and long-term consequences. We made the questionnaire survey and collected 516 answers. After that, we performed exploratory analysis (Multiple regression analysis) and confirmatory analysis (Covariance structure analysis). As a result, we confirmed that "Expectation in the Recruiting"plays an important role in increasing HR Outcomes.
