在传统的经营模式下企业的产品开发是以职能为基础的产品开发 ,营销部门通常把产品需求文件“抛过墙”给设计部门 ,而设计部门在完成了产品的设计之后 ,又将设计图纸“抛过墙”给制造部门 ,然后制造部门再把产品“抛过墙”给分销部门和服务部门 ,最终将产品“抛过墙”给客户。 In the traditional business model of enterprise product development is based on the function of product development, marketing departments are usually the product demand documents “throwing the wall” to the design department, and design department in the completion of the product design, and design drawings “Throwing the wall” to the manufacturing department, and then the manufacturing department “throwing the product over the wall” to the distribution and service sectors, eventually “throwing the product over the wall” to the customer.
