Global leaders should be clear about their personal values and beliefs. They must be seen as consistent in their choices and actions, not as chameleons that change all the time. If they are not clear about their convictions, they are much more likely to change their position with any change in trends or with the latest opinion poll, which will cause others to distrust what they say and do. This lack of clarity can be combated with training and vision. For instance, at Merck & Co., a leading research driven pharmaceutical products and services company, leaders are trained never to sacrifice longterm patient care in order to make a profit for the corporation.
