To maximize the effectiveness of a decision, it is necessary to support decision-making with integrated methods. It can be assumed that subjective evaluation (considering only absolute values) is only remotely connected with the evaluation of real processes. Therefore, relying solely on these values in process management decision-making would be a mistake because this might lead to the lack of agreement between the criteria of the process. The absolute values of criteria are required for decision making, while the integrated criteria evaluation is necessary for making consistent decisions, taking into account the relative values of the criteria as well.
