Faced with the global context, companies are called upon not only to become "lean", favoring the total quality approach and the development of a value chain based on the elimination of any kind of waste or loss, but above all to be also "agile" with an emphasis on perfect market knowledge and the judicious use of the notion of a virtual company to exploit the opportunities that arise in a volatile market. To do this, the postponement strategy approach is one of the innovative and efficient solutions enabling firms to better adapt to the new economic requirements thanks to the combination of these two complementary concepts as well as the positioning of the decoupling point. A quantitative study on the applicability of this approach will be carried out on a sample of 42 Moroccan aeronautical companies.
