       ①范进因没有盘费,走去同丈人商议,被胡屠户一口啐在脸上,骂了一个狗血喷头,道:“不要失了你的时了!你自己只觉得中了一个相公,就‘癞蛤蟆想吃起天鹅肉’来!……像你这尖嘴猴腮,也该撒抛尿自己照照!不三不四,就想天鹅屁吃!……”一顿夹七夹八,骂的范进摸门不着。辞了丈人回来,自心里想:“宗师说我火候已到,自古无场外的举人,如不进去考他一考,如何甘心?”因向几个同案商议,瞒着丈人,到城里乡试。出了场,即便回家。家里已是饿了两三天。被胡屠户知道,又骂了一顿。 ……

       ②范进不看便罢,了一遍,又一遍,自己把两手了一下,了一声,道:“噫!好了!我中了!”说着,往后一交跌倒,牙关咬紧,不省人事。老太太慌了,慌将几口开水灌了过来。他爬将起来,又拍着手大笑道:“噫!好!我中了!”笑着,不由分说,就往门外飞跑,把报录人和邻居都吓了一跳。走出大门不多路,一脚踹在塘里,挣起来,头发都跌散了,两手黄泥,淋淋漓漓一身的水。众人拉他不住,拍着笑着,一直走到集上去了。……”

       ③当下众邻居有拿鸡蛋来的,有拿白酒来的,也有背了斗米来的,也有捉两只鸡来的。娘子哭哭啼啼,在厨下收拾齐了,拿在草棚下。邻居又搬些桌凳,请报录的坐着吃酒,商议他这疯了,如何是好。报录的内中有一个人道:“在下倒有一个主意,不知可以行得行不得?”众人问:“如何主意?”那人道:“范老爷平曰可有最怕的人?他只因欢喜狠了,痰涌上来,迷了心窍。如今只消他怕的这个人来打他一个嘴巴,说:‘这报录的话都是哄你,你并不曾中。’他吃这一吓,把痰吐了出来,就明白了。”众邻都拍手道:“这个主意好得紧,妙得紧!……”

       ④范进一面自绾了头发,一面问郎中借了一盆水洗洗脸。一个邻居早把那一只鞋寻了来,替他穿上。见丈人在眼前,恐怕又要来骂。胡屠户上前道:“贤婿老爷,方才不是我敢大胆,是你老太太的主意,央我来劝你的。”邻居内一个人道:“胡老爹方才这个嘴巴打得亲切,少顷范老爷洗脸,还要洗下半盆猪油来!”又一个道:“老爹,你这手明曰杀不得猪了。”胡屠户道:“我那里还杀猪!有我这贤婿,还怕后半世靠不着也怎的?我每常说,我的这个贤婿,才学又高,品貌也好,就是城里头那张府、周府这些老爷,也没有我女婿这样一个体面的相貌……”说罢,哈哈大笑。

The majority of successful senior managers do not closely follow the classical rational model of first clarifying goals, assessing the problem, formulating options, estimating likelihood of success, making a decision, and only then taking action to implement the decision. Rather, in their day-by-day tactical activities, these senior executives rely on what is vaguely termed "intuition" to manage a network of interrelated problems that require them to deal with ambiguity, inconsistency, novelty, and surprise; and to integrate action into the process of thinking.

Generations of writers on management have recognized that some practicing managers rely heavily on intuition. In general, however, such writers display a poor grasp of what intuition is. Some see it as the opposite of rationality; others view it as an excuse of capriciousness.

Isenberg’s recent research on the cognitive processes of senior managers reveals that managers’ intuition is neither of these. Rather, senior managers use intuition in at least five distinct ways. First, they intuitively sense when a problem exists. Second, managers rely on intuition to perform well-learned behavior patterns rapidly. This intuition is not arbitrary or irrational, but is based on years of painstaking practice and personal experience that build skills. A third function of intuition is to synthesize isolated bits of data and practice into an integrated picture, often in an "Aha!" experience. Fourth, some managers use intuition as a check on the results of more rational analysis. Most senior executives are familiar with the formal decision analysis models and tools, and those who use such systematic methods for reaching decisions are occasionally suspicious of solutions suggested by these methods which run counter to their sense of the correct course of action. Finally, managers can use intuition to bypass in-depth analysis and move rapidly to find out a plausible solution. Used in this way, intuition is an almost instantaneous cognitive process in which a manager recognizes familiar patterns.

One of the implications of the intuitive style of executive management is that "thinking" is inseparable from acting. Since managers often "know" what is right before they can analyze and explain it, they frequently act first and explain later. Analysis is invariably tied to action in thinking/acting cycles, in which managers develop thoughts about their companies and organizations not by analyzing a problematic situation and then acting, but by acting and analyzing in close concert.

Given the great uncertainty of many of the management issues that they face, senior managers often initiate a course of action simply to learn more about an issue. They then use the results of the action to develop a more complete understanding of the issue. One implication of thinking/acting cycles is that action is often part of defining the problem, not just of implementing the solution. (454 words)
