Transformational leadership is one of the most practiced and researched areas of management, and most of these studies use the questionnaire form(s) developed by Bass, who also is the father of the concept. The aim of this study is to explain the four dimensions of transformational leadership construct developed by Bass in order to increase the consistency between theoretically-defined transformational leadership behaviors and actually observed and/or expected ones. In this respect, items measuring the degree of transformational leadership capability of a leader were studied and some ambiguous items were chosen to further describe them. 47 participants from different nations were asked to evaluate the meaning of those items by asking their opinions about the "specific courses of action a leader takes to behave in that particular way". Results display that the views of the participants were a valuable tool to make the ambiguous items more concrete. Besides the so-called fuzzy items, other items and theory are also discussed and defined as of practical usage by the authors. Doing so, our intention is to actually define what a transformation leader needs to transform his/her company and lead the change. The discussion part includes both results from the study and our decoding of the theory and literature, to help not only the practitioners imbibe lessons but also academics to comprehend what transformational leadership stands for.
