Research has to focus on the cost benefit of factors such as reliability. As reliability increases, manufacturing costs and the final cost of the system will decrease. Having 30 percent junk at the end of a production line not only costs a fortune but also creates an opportunity for a competitor to take your idea and sell it to your customers.
Central to the process of improving reliability and lowering costs is the intensive and widespread use of design software, which allows engineers to speed up every stage of the design process. Shortening each stage, however, may not sufficiently reduce the time required for the entire process. Shortening each stage, however, may not sufficiently reduce the time required for the entire process. Therefore, attention must also be devoted to concurrent engineering software with shared databases that can be accessed by all members of the design team.
As we move more fully into the Information Age, success will require that the engineer possess some unique knowledge of and experience in both the development and the management of technology. Success will require broad knowledge and skills as well as expertise in some key technologies and disciplines; it will also require a keen awareness of the social and economic factors at work in the marketplace. Increasingly, in the future, routine problems will be expected to work cooperatively in solving more challenging, more demanding problems in substantially less time. We have begun a new phase in the practice of engineering. It offers great promise and excitement as more and more problem-solving capability is placed in the hands of the computerized and wired engineer. To assure success, the capability of our tools and the unquenched thirst for better products and systems must be matched by the joy of creating that marks all great engineering endeavors. Mechanical engineering is a great profession, and it will become even greater as we make the most of the opportunities offered by Information Age.

机械设计机械设计是什么？这意着事物的机械性质的系统。对于大部分机械设计需要利用数学，材料科学，科学和工程力学。
整个设计过程对我们益处。如何开始机械设计呢？是不是工程师拿张空白稿纸坐到他的桌前那么简单呢？如同他那少量的想法，然后呢？那些因素影响或者控制所做出的决定呢？最后，如何结束这个设计过程呢？
有时，虽然并不总是如此，工程师认识到一种需要并且决定对此做一些工作时，设计就开始了。认识的哦啊这种需要，并用语言将其清楚地叙述出来，常常是一种高度创造性的工作。因为这种需要可能只是一个模糊地不满，一种不舒服的感觉，或者是感觉到了某些东西是不正确的。
这种需要往往不是很明显的。例如，对食品包装机械进行改进的需要，可能是由于噪音过大，包装重量的变化、包装质量的微笑的但是能够觉察得出来的变化等表现出来的。
