This research aimed to analyse the relationships between chefs' knowledge, learning with suppliers and restaurant sales performance.
A performance model was formulated, and the hypotheses were evaluated using partial least squares (PLS). The research questionnaires were sent by post to the chefs who confirmed leading for product innovation in the restaurants and yielded 166 completed questionnaires.
Whilst the chef is developing new products, restaurant operations should pay attention to the supplier's subsequent income convenience. Additionally, through the cooperation of chefs and suppliers, innovative and valuable products can improve restaurant performance and maintain a competitive advantage. Moreover, tacit knowledge sharing can become a chef's ability to learn and provide competitive advantages and benefits to restaurants.
Valuable products can be advantageous to restaurants and increase restaurants' operating performance. Moreover, the development of new products is important for restaurants' operations. Further, chefs will understand market trends and make the culinary innovation process closer to the market by learning from their colleagues and partners. Additionally, chefs prefer culinary creation to provide more tacit knowledge with suppliers.
