This research stems from two questions: 1) What is the impact on scientific knowledge in management when it leaves the theoretical field of study to become an object of teaching? 2) Regarding the concepts taught in management how is it possible to preserve the initial strength they had when they were first introduced in the scientific field? The general issue of the articulation between epistemology and didactics in management leads to implement an original methodology for analysing a management concept in five steps: analyse the concept through a common sense approach and representations, study its scientific meaning from the treatises and works of great authors, identify the treatment of the concept in the national curriculum, study school textbooks, investigate the epistemological obstacles which hinder pupils from constructing the concept. This methodology applies here to the concept of decision, a central concept in management, which is precisely analysed in this research, and to the way it is apprehended didactically with a view to teaching students attending technological courses. Exploring the national curriculum and school textbooks has shown that the concept of decision adapted for teaching purposes is a specific construct which was created by textbook writers, half way between common sense and scientific sense. It has been made clear that the epistemological knowledge of management concepts is not enough to preserve their original strength. However the problematization of management concepts and the didactic study of their conceptualization require an epistemological culture.
