The idea to use a system approach to understand the problematic of the development of the technology seems seductive. The first part of the paper presents the classical approach and shows its limitations, mainly those due to the nature of the problem and its numerous dimensions.This hard approach has to be modified to exceed these limitations and to consider the human characteristic of the problem and its environment, a soft approach is then described.The second part is a schematic analysis of the problem of technology development and Morocco is selected as a case study.This analysis shows the exogeneous characteristic of the technology cycle in this country.
