The demands that are placed on product and process within the food production industry are interconnected. Therefore, it is not appropriate to use a largely sequential approach to designing a production facility, where you first address the primary function of the product, i.e. product quality and then consider other issues such as safety, hygienic design, cleaning, flexibility and traceability. There is a need for integration of these issues, in order to make the best decisions and to balance the different needs.
