Deterministic Design: Best Engineering Practice 

确定性设计:最佳工程实践

Engineering is distinguished from tinkering by the former’s use of fundamental principles to stimulate and assist the creative process and guide implementation; in addition, engineering implies the use of analytical and computational tools to optimize a project. These tools are not only concerned with classical analytical engineering endeavors required to move the project from the concept to production stages, they are also concerned with keeping the project on schedule and on budget. An engineer must have a positive attitude towards the design process and project management. Best engineering practice must be the standard to which all team members adhere if a project is to be successfully completed on time and on budget:

工程并不是普通的修补,工程师通常需要应用基本原理来模拟或者帮助创造性过程,并帮助指导整个产品设计的实施。此外,工程问题都需要理论分析和计算工具来优化产品设计。这些优化工具,不仅包含了推动设计从方案到细节的经典工程分析方法,而且还牵扯到一些保证设计过程符合时间和成本限制的方法。设计工程师们必须对设计过程和项目管理保持乐观的心态。如果要求在特定的时间和成本内成功完成产品设计,那么团队的每个成员必须支持和首肯最佳工程实践。

In between these two extremes are engineers who may have good intentions, but they are not applying fully engineering principles to their own actions. Some engineers just get too excited about a project, so they jump on their workstation horses and attempt to gallop off into the pretty CAD background; however, ignoring best engineering practice is tantamount to forgetting to untether the horse! In a similar manner, some engineers misguidedly substitute trial and error for careful analytical or computer modeling and optimization. 

处于以上两种工程师类型之间的,是一些怀着好的设计意愿,但是无法根据设计原理完成好工作的工程师们。一些工程师对设计项目非常兴奋,恨不得跳上工作台,好想和CAD美丽的背景画面融为一体一样 。但是,最佳工程实践被抛诸脑后了,这是造成寻夫狂野思维的关键性因素。同样的,许多工程师通过试验和试错来取代严谨的分析、建模和优化,这也是不可取的。

Unfortunately, too often engineers think that a poorly defined problem gives them license to proceed in a poorly defined manner, and they excitedly set off in too many directions at once. Such haphazard approaches to problems indicate a lack of deep understanding, and this can lead to an internal lack of confidence which makes the engineer think they had better think of even more “out of the box crazy” ideas. A vicious cycle forms and the project falls way behind schedule. Other sad problems include endless meetings where format dominates over function and trying to do too much which results in a Rube Goldberg type solution. All of these issues can lead to a great idea at the last moment, but it just will take a little more time, even though the project is way behind schedule, and the idea has yet to work even a little bit. 

不幸的是,通常工程师们都认为设计问题没有清晰描述的情况下,他们的设计方式可以随意的进行。而且,他们往往一次性就激动的朝多个目标进发。这种危险的设计方法,是由于工程师们缺乏对问题的深入理解造成的,而且往往造成工程师们因为缺乏信心而产生多想些“非常规”的主意,就能找到问题答案的错觉。恶性循环就是这样起作用的,最终项目无法按时完成。其他常见的问题还包括无休止的会议讨论,繁文缛节而不是设计的功能本身变为讨论议题,甚至会出现非常复杂的解决方案。所有这些问题都可以最后演化成一个好的设计概念,只是项目时间却一拖再拖。此外,即使项目时间延后,这个设计本身其实还是稍微有点用的。

To help combat these common problems, the ISO 9000 and ISO 9001 family of standards were created by the International Standards Organization. These standards are concerned with making sure companies have best engineering practice procedures in place. Soon it will be difficult for a company to sell its products if it is not ISO certified; therefore it is advisable that every engineer, whether practicing or in training, develop best engineering practice habits. 

为了克服这些普遍问题,ISO协会颁布了9000和9001标准。通过遵守这些标准,公司可以实践最佳工程设计的过程。迟早,不符合ISO标准的产品会很难销售。所以,最好每个工程师,都要形成最佳工程实践的习惯。

Create a simple web page to document your understanding of the problem, your solution approach as you initially see it (it will change!), your schedule, and your progress. Document your thought process so others may follow and learn and make useful suggestions. Review the work of others so that you may help them and in the process, help yourself. Enter your observations about the contest and any initial ideas that come to mind. 

设计自己的网页来记录设计问题,记录第一眼的解决方案(解决方案会演化和改变)和你的时间规划以及进步。通过记录自己的设计过程,其他人可以顺利的学习、验证甚至提出有用的建议。同样,可以通过评审别人的设计来帮助别人或者自己来熟悉设计过程。一定要记录下自己的观察和第一眼的想法。
