PRODUCTION— GENERAL CONSIDERATIONS - Trong giao dịch với chủ đề phức tạp của sản xuất, nó cảm thấy được thuận tiện hơn để thảo luận về các khía cạnh bao gồm hầu hết những cân nhắc trong bất kỳ quá trình đúc sẵn trong chương này, và mô tả quy trình cụ thể trong chương sau. 5,1 NHÂN VIÊN Thiết lập bất kỳ quy trình sản xuất đòi hỏi phải có ít nhất hai người ở các vị trí quản lý được trực tiếp liên quan đến sản xuất mà.

All other workers rely on this person for a mix that will satisfy the process and property requirements.
