發明競爭理論大師Porter自己公司都倒閉了,可見他的理論根本是狗屎,但遺毒卻不絕啊!
卻被一些笨笨的管理人抱著不放,自以為跟上時代

我知道很多從美國回來的管理人,愛搞這一套

From Wiki: Vitality curve
Rank-based employment evaluation:
Jack Welch's vitality model has been described as a "20-70-10" system.
The "top 20" percent of the workforce is most productive, and 70% (the "vital 70") work adequately.
The other 10% ("bottom 10") are nonproducers and should be fired.
Rank-and-yank advocates credit Welch's rank-and-yank system with a 28-fold increase in earnings (and a 5-fold increase in revenue) at GE between 1981 and 2001.
