The document describes the brigade (or kitchen) system developed by Escoffier to organize roles in hotel kitchens and dining rooms. Key positions in the kitchen brigade include the chef, sous chef, and various station chefs overseeing specific dishes or cooking methods. Similarly, the dining room brigade outlines roles like the maître d'hôtel and various levels of waitstaff. The brigade system aims to streamline operations by assigning clearly defined tasks to each role.
