Considering great importance in conducting organizational activities, business decision-making is the subject of numerous researches by scientists from various disciplines. Some available results of empirical research indicate that half of the decisions in organizations end in failure. The purpose of a paper is to analyze the concept of evidence-based management as one of the possible approaches available to improve decision-making process in organizations and to explore the representation of elements of this concept in a real project. The basic idea of the evidence-based management concept is that quality decision-making is based on the use of critical thinking and the best available evidence for a decision. Four sources are proposed for collecting evidence: scientific literature, organizational data, practitioners professional expertise and stakeholders values and concerns. The analysis of the concept resulted in description of proposed steps in certain phases of the decision-making process and methods of collecting evidence from purposed sources by using various existing methods and techniques of data collection. The results presented in the case study indicate the use of all four proposed evidence sources in some form in decision-making processes within the e-mobility project and high potential of developed IT solution for supporting future decision-making processes in the field of e-mobility. In addition, the cooperation of the academic and business community was assessed as effective for achieving the goals of a specific development project.
