    In order to accomplish management objectives, they must be made certain and efficient by identifying true assignments that need to be prioritized, by clarifying measures to achieve them, and by putting them into implementation. This justifies the significance of Policy Management. In this article, I'd like to describe the necessity of Policy Management, to define what Policy Management is, and to expand upon the purpose and outcome of Policy management. A careful, step-by-step description of the procedures is also introduced. Finally, ten key points are proposed by which to proceed with Policy Management effectively. This article will provide you with specific procedures for effective Policy Management.

    When carrying forward a quality management system, policy management is activity which works on preponderantly in TQM. When top management do business, strategic management policy is hung up, management policy is sent to all the employees from top management, and each operating department draws up the activity plan in alignment with that policy, and puts into action. The example that Komatsu has aimed at improvement of physical condition by policy deployment as Komatsu's strong point is introduced.

    The declaration to challenge the Deming Prize brought about a drastic change in our policy management. While our conventional policy management merely aimed to accomplish goals, the current one is giving importance not only to goal achievement but also to how we foster middle management executives and how we accomplish business goals. I would like to introduce actual examples of our efforts for them.

    In 1981, "GQM," which is described as TQM at GC, was introduced in order to adapt to any environment and establish flexible and strong corporate base, and in 1995, GC has started the "Vision Management" as one of most important strategies of the company management. It is not too much to say that our "HOSHIN KANRI" has been largely contributed to achieving our vision. "Presidential Diagnosis" is an unique feature of our company to enhance HOSHIN KANRI. It is implemented 50 times throughout a year, which reinforces the favorable PDCA cycle.

    We have practiced policy management and continuously turned PDCA through various management activities in order to have the policy management taken a firm hold on our organizational culture as the most critical, basic factor of Quality Management in our company. Management environment is dynamic ; but, policy management is universal. Therefore, it is imperative for us to seriously practice STQM which reinforce policy management by enlightening and perpetuating its substance.

    The Mahalanobis-Taguchi (MT) method is one of statistical methods for analyzing asymmetric discriminant data in the field of quality control and medical diagnosis. However, some researchers point out that the accuracy of the MT method is deteriorated when (i) the data generating process of a given normal group is not based on an elliptical distribution, and (ii) some of variables are highly correlated with each other. In order to solve these problems, we propose a new asymmetric discriminant analysis "the Kernel MT method," which is formulated by introducing the kernel technique used in the field of machine learning into the MT divergences proposed by Miyakawa and Nagata (2003). Through the numerical experiments and the application of the kernel MT method to the sensory evaluation problem of the wine quality, we show that the kernel MT method is superior to the MT method.

    When we observe a contingency table including binary variables X and Y, this paper considers a problem of evaluating a logistic regression coefficient of X on Y from the data. Under the situation, this paper proposes a weak collapsibility condition in which the sign of the regression coefficient of X on Y does not change by the addition/omission of Z. In addition, we show the collapsilibity conditions in logistic regression models are different from those in Gaussian linear regression models. Futhermore, under the weak collapsibility condition, we discuss a covariate selection problem from the viewpoint of the estimation accuracy, and show that selecting a covariate that has a direct effect on an outcome variable cannot always improve the estimation accuracy, which is contrary to the situation in Gaussian linear regression models.
