The development of Traditional Food Products (TFP) is an important link to ensure sustainable territorial development which depends on several factors particularly the quality that is supposed to meet consumer demands. The quality of these products remains the most important criterion that reflects the approach followed to ensure the safety, health and environmental protection along the production chain. The aim of the present work is to evaluate the significance and limitations of the adoption of the QHSE approach by producers. It is based on standards of quality (ISO 9000: 2005), safety (OHSAS 18000: 2007) and environment (ISO 14000: 2004) to make a diagnosis of the integrated management system optionally followed by eight professional organizations (POs) at the Tafilalet oasis. The diagnosis is carried out via questionnaires concerning five areas: environment management, health and safety management at work, quality management, maintenance management and personnel management. Questions for each axis are divided into three levels: strategic, tactical and operational. This division aims to gain a better understanding of performance in decision-making. Preliminary results of the diagnosis were subjected to statistical analysis. They show a level of overall performance between 16 and 60.7%, weakness in performance of the environment management and superior performance level of the personnel management. Indeed, most of the POs diagnosed need improvement in all axes, especially in the quality, health and environment management.
