模型的制作关系着产产品的成功，如果产品在模型制作的时候都没有达到预期的效果，那么肯定不能算是成功。

       实体图像也叫作“展示和叙述”模型促进营销、研发和管理之间的相互影响，即使有时它的轮脚很粗糙而且仅可见其总的特点。假如研发工程师以技术图纸形式提出的建议可能无法或根本无法完全被市场和管理人员理解时，模型会更加广泛地被人们所采用，使用程度比想像程度更高。另一方面，如果可能，一个物理模型以符合产品要求的方式，并且按初始比例简化，以便使任何人都能在设计和造型上做出正确的评价。
      在存在缩短产品研发时间和快速、畅通地交流的情况下，产品寿命的减少、持续的价格压力的下降和对多学科合作等要求架集到了一起，模型和原型改善了交流的质量。
      不同学科的专家可以从他们专业的观点出发研究产品开发的每一个阶段，井且能够在较早的阶段做出改进。例如产品上的某个孔，对于实际技术人员来讲可能无关紧要，如果没有它可能愈味着产品将无法通过铸造制造出来。这样的模型被看作功能性原型，因为在它们的帮助下，可以测试出产品的单一功能。因此，模型具有重要的辅助作用，可以影响在研发团队内部和不同团队之间的交流，还有对总体的创新、锗误的尽早发觉和概念的早期回班产生积报的影响。

     Modelling of the relationship with the product 's success, if the products in the production model of the time will not achieve the desired effect, then certainly won't be successful.
    The image of the entity is also called "show and the" model to promote the marketing, research and development and management of the mutual influence between, even if sometimes it's foot is rough and is only visible in its general characteristics. If the engineer with technical drawings form recommendations may not or cannot completely by the market and management personnel to understand, the model will be more widely adopted, using higher degree than imagination. On the other hand, if possible, a physical model to meet the product requirements, and according to the initial ratio of simplified, so that anyone can design and modeling of the correct evaluation.
    In the presence of shortening product development time and fast, smooth communication, the life of the product is reduced, sustained price pressure drop and on multidisciplinary cooperation request frame set together, model and prototype improve the quality of the communication.
    Experts from different disciplines can be from their professional perspective of product development at each stage, well and can make improvements in early stage. For example on the products of a hole, it might be of no great importance for practical and technical personnel, if not it may mean more products will be produced by casting. Such a model is regarded as a functional prototype, because in their help, can test the product of a single function. Therefore, the model has the important supporting role, can influence on R & D team interior and different communication between the group, and to the overall innovation, germanium error early found and the concept of early return to classes to produce positive effect.
