Responsible decisions are taken both in our everyday lives and in business processes of big enterprises. Decisions have an effect on our future, the efficiency of our work, our successes. There are decisions which need an especially substantial and persuasive decision process because taking them is complex problem or their consequences are important to us. In these cases the decision process is particularly important to be well-established and clear from the point of initialization to the point of defining the final solution. The most sensitive part of a decision process is the human factor, the inconsistency of the Decision Maker(s) (DMs). Hence we should pay due attention not only to developing the most appropriate algorithm but also to improving the intuitive efficiency of the DMs. The impact of internal factors on inconsistency like the type of the problem (subjective or objective), the size of the pairwise comparison matrix or the order of filling have been studied in several papers (i.e. [2,9]). However, the authors of these papers usually ignore the human factor of the decision process. We investigated what by what means and how we can enable the DMs to make the most consistent decision inspired by design.
