模型的制作關(guān)系著產(chǎn)產(chǎn)品的成功，如果產(chǎn)品在模型制作的時候都沒有達到預期的效果，那么肯定不能算是成功。

       實體圖像也叫作“展示和敘述”模型促進營銷、研發(fā)和管理之間的相互影響，即使有時它的輪腳很粗糙而且僅可見其總的特點。假如研發(fā)工程師以技術(shù)圖紙形式提出的建議可能無法或根本無法完全被市場和管理人員理解時，模型會更加廣泛地被人們所采用，使用程度比想像程度更高。另一方面，如果可能，一個物理模型以符合產(chǎn)品要求的方式，并且按初始比例簡化，以便使任何人都能在設計和造型上做出正確的評價。
      在存在縮短產(chǎn)品研發(fā)時間和快速、暢通地交流的情況下，產(chǎn)品壽命的減少、持續(xù)的價格壓力的下降和對多學科合作等要求架集到了一起，模型和原型改善了交流的質(zhì)量。
      不同學科的專家可以從他們專業(yè)的觀點出發(fā)研究產(chǎn)品開發(fā)的每一個階段，井且能夠在較早的階段做出改進。例如產(chǎn)品上的某個孔，對于實際技術(shù)人員來講可能無關(guān)緊要，如果沒有它可能愈味著產(chǎn)品將無法通過鑄造制造出來。這樣的模型被看作功能性原型，因為在它們的幫助下，可以測試出產(chǎn)品的單一功能。因此，模型具有重要的輔助作用，可以影響在研發(fā)團隊內(nèi)部和不同團隊之間的交流，還有對總體的創(chuàng)新、鍺誤的盡早發(fā)覺和概念的早期回班產(chǎn)生積報的影響。

     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.
