Resumen
The important managerial decision-making and the development of policies, strategies, internal normative acts and procedures must be solid grounded for efficient achieving of their objectives. To this end, the evidence-based approach uses various types of evidence, a leading role having those scientific, and the critical thinking. The evidence from behavioral sciences is especially important when the decisions objectives involve behavioral elements. They also help to ensure the rationality of any decision-making process. The concern for the use of behavioral sciences research in the decision-making preceded the occurrence of evidence-based approach. The increased knowledge fund of organizations, the access to the best practices and to the relevant scientific research findings represent only the initial stages of the evidence-based approach implementation and functioning. The ensuring of their effective use calls for special skills training among staff, the creation of tools and organizational mechanisms and of a facilitating organizational culture. This paper argues the need to integrate two approaches that promote the decision-making based on scientific evidence, the evidence-based approach and the use of behavioral and social sciences in the decision-making, to potentiate the contribution of the behavioral sciences to the increasing of the decision-making efficiency. The efforts made in this paper had overall objective to prepare and facilitate the use of research evidence provided by behavioral sciences in the organizational decision-making process by presenting the main concepts and knowledge in the field and by proposing an outline procedure specifically developed.
