What does "PDCA" mean?

The PDCA Cycle was originally conceived by Walter Shewhart in 1930's, and later adopted by W. Edwards Deming. The model provides a framework for the improvement of a process or system. It can be used to guide the entire improvement project, or to develop specific projects once target improvement areas have been identified.

"Plan ---do ---check ---action"
So great! It also can be used in our design work and make our team effective!

　PDCA四个英文字母及其在PDCA循环中所代表的含义如下：
P（Plan）--计划，确定方针和目标，确定活动计划；
D（Do）--执行，实地去做，实现计划中的内容；
C（Check）--检查，总结执行计划的结果，注意效果，找出问题；
A（Action）--行动，对总结检查的结果进行处理，成功的经验加以肯定并适当推广、标准化；失败的教训加以总结，以免重现，未解决的问题放到下一个PDCA循环。

这几天接触到了一个新的循环工作法，感觉用在我们的设计过程中以及团队建设管理上都会很nice。忙完了这阵子的比赛，应该要好好学习一下PDCA，然后在cooper里来个小培训，呵呵。
