Simplicity: 白石老人画虾
“虾的精神状态,虾的有弹力的透明体,虾
在水中浮游的动势。把艺术造型
的“形”“质”“动”三个要素完满的表
现出来。
这样丰富的内容,齐白石先生用的是及简
练的笔墨,不能多一笔,也不能少一笔,
一笔一笔可以数得出来。”——叶浅予

Simplicity: 元青花
青花“鬼谷下山”罐
UPerform Your Agile and Project Performance Partner
Simplicity: 元青花
2005年7月12日,英国伦敦拍卖了一件“鬼谷
下山”元青花大罐,当时的成交价折合人民
币是2.3亿,以当天的国际牌价可以买两吨
黄金。
以体积而论,这件元青花是全世界范围内最
贵的瓷器;单件工艺品的最高价,也是这
件元青花创造的。中国古代陶瓷艺术在世
界上的地位非常高,全世界的人用金钱表
示对我们文化的尊重。

Simplicity: LOHAS 乐活
这并不是一个刚刚兴起的东东,由于“乐活族”的生活方式既简单
又时尚,已经迅速席卷全球。据统计,目前在美国每4人中就有一
人是“乐活族”,欧洲约是三分之一。
关注他们不仅仅是因为他们日渐壮大,更主要的是他们倡导的生活方
式———一种关注健康的,环保的和可持续发展的生活方式!

Simplicity: MUJI 无印良品
UPerform Your Agile and Project Performance Partner
Simplicity: MUJI 无印良品
“无印良品出品的商品,在设计上是简单无华的,
但我们不是一味地在奉行极简主义而已。因为无
印良品这个品牌,就像是个 空 的容器一般,
能够接受不同的观点,也能够无拘无束的发挥。
我们追求「简约无华」的概念落实在很多事物上,
像是在制程中节省能源、产品价格实在、设计造
型简单、质地自然…等。无印良品希望在各方面
都能做到「简约无华」,将价值的真实意义还
原。”

insists that Simplicity is key to success.
“Business isn’t complicated." he says. “The complications
arise when people are cut off from information they
need.”

Simplicity: Technical Excellence
“the hallmark of the professional
programmer is not in the complexity of
the code they produce, but rather in
the simplicity. When you can take a
complex problem, and solve it with
simple code, you are a professional
programmer”
Daryl Banttari webapper.net

Simplicity: XP-from Kent Beck
The 2nd XP value is simplicity:
“What is the simplest thing that could
possibly work?”
“XP is making a bet. It is betting that it is
better to do a simple thing today and pay a
little more tomorrow to change it if it needs
it, than to do a more complicated thing
today that may never be used anyway.”

Welch’s 5 Keys
•  Candor—Everybody should look for opportunities to make
change rather than issue rosy forecasts and hope for the best.
•  Simplicity—You’ve got to have it if you want your organization
to be effective.
•  Self-confidence— “Frightened, nervous managers use
thick, convoluted planning books and busy slides.” Welch notes.
•  Two-way communication
•  Evaluation and reward—We have to know if our
people are open and self-confident, if they believe in honest
communication and quick action.

Review, 1989

Simplicity: Technical Excellence
•  你永远不会需要它 You Aren't Gonna
Need It (YAGNI)
•  不要重复自己 DRY (Don’t Repeat
Yourself)
•  好的代码就是文档 Self-Documenting Code
– 在写代码注释之前,问一下你的伙伴怎样能够
把代码写的不言自明
– 注释好像不错,但是它是不是说明你的代码有
些复杂了
