Points on RIF

Points on RIF June 3rd, 2006

RIF, or more commonly known as layoff, starts when the company learned it has more employees than it needs. Why? Most of the time, the company did not plan well. It is only academic to dig out the reasons and many MBA cases did. For you, focus on future, not past.

RIF is not cheap for the company that incurs severance costs, legal expenses, disruptions to normal operations, demoralization of employees, and, usually, bad publicity. If not done well, the company may lose critical productivity that lead to loss of revenue and another RIF — so called death spiral.

You can bet that some aspects of the RIF operation will not be done well. It is part human nature to avoid unpleasant tasks and part rushed. Try to appreciate the works senior managers must have done and understand that they actually did not have much time and were very constrained on maneuvering rooms.

The top executives of the company first decide to invest less on particular investment areas, to reallocate its resources, or both. This step is time consuming and gut wrenching. Sometime, we, mid-level executives, get a glimpse of board-room lock-horns. Most of the time, we simply observe the absence of senior executives for days, during which we get urgent and cryptic requests of information. When they come out of the smoke-filled room (OK, this is for drama, they are usually many rooms involved and execs these days do not smoke), each gets a number and a set of guidelines.

Each of the top execs then summons her staff, or few selected advisors, to plan for her number. This process cascades downward to roughly functional VP or director level. At this level, the single number has morphed into a set of actions that include the elimination/reduction of programs, number of people to layoff, a set of communiques, and a schedule. This is the time, you, the line managers, get busy.

First, learn the communiques and guidelines. Practicality does not allow thorough communication. Do not wait for the presentation or in-person training. Go to the web site, read the email, and study the guidelines. Ask questions only after you have done the homework.

Expect whoever planning this operation to have been hurried. Ask questions so that you can do your jobs, there is no need to criticize. This is hard for everyone, not just you. When you get the details, see if they will lead to disasters. If so, escalate quickly, but do not be insistent. No whining and no stating the obvious. Statements such as, “Do you realize this will impact morale and productivity?” is stupid and insulting. But, “if you substitute this with that, company can save more money, or avoid a major disaster” will be much appreciated.

It is human to dig dirt and gossip. That does not make these activities productive or less hurtful. Discourage by smiling and nodding politely. Gossips starve on the lack of excitement from the recipients.

Although not obvious, being laid-off is not really a bad thing. There is no need to be saddened. Sun gives a relatively generous severance and benefits to those laid-off. In a relatively healthy economy (like China), the laid-off employees usually find new job before the severance are used up.

In this industry, each individual faces competition from around the world. Someone from somewhere is trying to have your job, and vice versa. The only protection is your adaptability and professional competency. You are on a treadmill to upgrade yourself all the time. If you are not learning new skills so that you can do something totally different in a few years, you are risking being obsolescent. What are you learning now? Why would the employer pays you so much?

Being part of a lay-off operation bring this point close to home. If you are one that is receiving the package, thank the company to give you few months off to upgrade yourself. If you are a survivor, try to learn this lesson.

Wealthiest Man in the World

This is really an entry about a garden.

Mr. HE Shen (和珅, 1746~1799) died with about 800 million ounces of silver in his estate. That was 10 times China's government income. It is hard to imagine who will be wealthier than Mr. He in the 18th century.

乾隆 (QianLong, 4th emperor of the Qing dynasty, one of the most successful and respected ones in China history) trusted and loved him. Out of pure favorism, he promoted He Shen to pretty much the highest possible position in the government. He Shen made his fortune embezzling. During those 20 years in power, he amassed vast fortune. In 1777, when he was 31 and about 7 years in his accelerated career, he built this grandeur mansion. He lived there better than the emperor, with 45 wives (two foreigners) and numerous servants. The warehouse for all his possessions is a two-story building with about 100 rooms that categorized his collection.

乾隆's successor, 嘉庆 (JiaQing), bestowed him a piece of white cloth (so that he can kill himself gracefully) and confiscated all his belongings. 嘉庆's successor gave the mansion to 奕昕 (YiXing), the effective prime minister of the late Qing dynasty. 奕昕 is a royalty with the official title of 恭亲王 (GongQinWang: King Gong who is close to the emperor). People started to call the mansion 恭王府(GongWangFu, the house of King Gong). This is the largest, best built, and best preserved imperial style residential building in Beijing. The whole estate is about 60,000 square meters (more than 13 acres) and the garden is about 28,000 sq meters (6 acres) in area. Only the garden is open to the public.

恭王府 (GongWangFu) is in the area where tricycle HuTong tour is popular. Make sure you buy the “group guided tour” ticket. It is worth the 60RMB. English capable guides are available too.

The whole estate is obsessively decorated with 福 (Fu: good fortune). In Chinese, bat is pronounced similarly and you can see that all over the place, even a pond that shapes like one.

The climax of the 福 (Fu) obsession is a stele of the single Chinese character of 福. This stele is so well placed that even it was originally stolen from the palace, emperor 嘉庆 (JiaQing) could not take it back when he confiscated the rest of the estate. (Replicas from the rubbing of the stele is for sale.) The stele is known to have magical healing power and the possessor will be blessed with talents, offspring, longevity, lands, and, of course, good fortune. I bought one for good measure.

The pathway leading to the pinnacle of the garden is called 升官发财路 (career and fortune way). It is a steep slope up and you are supposed to walk up “in short steps, evenly, and quickly.” Hmm, why not? I am sure all those tourists that day, like myself, will experience the same with their career and fortune.

There is this one stone standing alone in the garden like a statue. On the top, there appears to have an engraving of 乐峰 (LeFeng: happy hill). But facing upward, where viewers standing on the ground cannot see, there was another character 独 (Du: solitary). The stone was then named “solitary joy stone.” That character changed the mood of the stone from joyous to sadness, since Chinese always treasure enjoyment of company and consider oxymoron to be joyous alone. People speculated that was the mood of Mr. YiXing when he was serving CiXi (慈禧), the famed empress of Qing dynasty. Poetic.

Temple of Guang Gong

Among many dissimilarities of Chinese is its religions, or the lack of an original one. The closest to a “native” religion is a form of multi-theist one.

Chinese generally believe all intensive and unique beings that ever existed live forever — a magnificent mountain range, a specular river, a hero who won many battles, a villain who slayed many innocent people, a daughter who sacrificed to save her father, etc. As a matter of fact, anything can be inducted into god-hood by someone erecting a shrine and offering few incenses. Becoming a god, or a spirit, is the easiest thing.


After the induction, the god needs to earn its followers. Typically, a follower offers few incenses and a prayer. If the god responded to the prayer, he or she will “return the favor” — a girl may offer a dance, a merchant may refurbish the temple, a bottle of wine will do, so will bowing three times for gratitude — whatever commensurate.

In Taiwan, two of them have amassed millions of followers. 媽祖 (Ma Zu) is the most popular one. Guano Gong (關公), whom I blogged about as the “red face,” is the other. He is a famous general that died in 219AD. He was known to be brave, loyal, wise, well-read, and good at managing money. If you pay attention, you can find a statuette of Guano in almost all Chinese restaurants.

When you visit Taipei next time, stop by 行天宮 (XingTianGong: Guano Gong's Temple) and feel the power of belief. I saw people kneel walking from the entrance all the way to pray. The are about 30 clergymen doing nothing but interpreting what General Guan's messages. How?

First, introduce yourself and describe the problem to General Guano, with few incenses raised above your head few times. After that, you throw two pieces of wood instruments, provided by the temple freely, to the ground. (See picture. If you can't read the instructions, it is not likely that you will perform this ritual by yourself. Right?) If they show the right combination, he has agreed to answer. You may now fetch a bamboo stick from a bunch. Each stick has a small inscribed number at the end. There is a shelf near-by that has stashes of pre-printed paper for each number.

With the paper clutched in your hand, you come back and do the wood ritual again. If General Guano confirms, the message is the right one. Otherwise, repeat the process.

The confirmed paper answers your question, but the language is usually archaic and vague. You are usually not wise enough to understand. No matter. Go wait in the line for one of the clergy. The interpretation is free.

Just remember to return to thank General Guano later. Thousands do.

Professionals train themselves

Professionals train themselves April 8th, 2006

Kevin, an engineering manager, was frustrated. Good projects do not come to his engineers. If there are no projects, there will be no accomplishments, and no advancements. China will feel like the high-tech colony of the 21st century and get only menial works and be stuck in the “low wage” end of the industry.

I felt for Kevin's despair. At the same time, I was astronished on how his young engineers have missed the basics and focused on the wrong things.

Like atheletes, good software engineers move up the career ladder will skills. It is quite simple, choose the arena, suit up and compete. The winners move on. The question is, “Are you training yourself everyday?”

The general categories for a software engineer evaluation are:

  • Credential:

    The pieces of paper that prove you qualified for certain tasks. The most basic ones are the diplomas. Then we have those issued by various institutes. These paper give the boss various degree of confidence that you can accomplish the tasks she needs you for. If the task has a commensurate higher job level, you may get the promotion tegether with the assignment.

    Credentials, particularly diplomas, also show your tenacity and conformity. You may not have learned much, but you stuck it out for years and met all requirements. If you can go through that, you must have what it will take to finish this project.

  • Experience:

    Young engineers hate to compete on experience. You are not qualified because you have never done this before. But how can you get the 1st project then?

  • Skills:

    Skills are easy. Although hard to describe precisely, an engineer know how skilled she is. Software, after all, is a craft. Within few minutes, an engineer would have sized up others and a pecking order is formed.

These basic three are part of all promotion considerations. The weights of them differ as career progresses. In general, Sun values credential the least, skills most, and experience a very close second. Ask. “Am I the most skilled and experienced among my peers?”
Like atheletic competitions, software career is meritocratic. Do not waste efforts on anything before mastering the basics.

Next time, when you have finished the project, try do a bit extra:

  1. Testability:

    How is the code testable? Is there test programs that automate the process? When problems surface in the system, how easy it is to isolate the bug?

    Along the same line is demo. How would you show someone your proud achievement? Did you write another piece of program to show it off?

  2. Usability:

    Is there a web-based interface? Is there a tool to make it easier? How is the user experience? Do not hide behind areas of technology. A kernel module or a device driver can have user interfaces just like a Java application. As long as a human being can use it, you need to consider usability.

  3. Elegance:

    Is the code efficient and pretty? Nicely modulized, neatly formated, appropriately named, cleanly inferfaced? How did you treat the global state variables? How much you rely on side-effect to accomplish works? Are you proud of this piece of work like a poet?

  4. Documentation:

    Did you comment the code well? Did you write the design document? Did you let the next person who is unfortunately stuck with your code know where to pay attention?

These are where you gain experience without the assigned project. There is always something extra you can do to make your project better. When you are doing that extra amount of work, you gain experience on areas you do not normally practice in. Choose what you need to practice and do the extra work there.

And you would have done something wonderful to yourself. When you are doing those, your manager will notice that you walked the extra mile and did the extra-currriculum work. That shows your diligence, willingness to learn, and potential.

Most importantly, you gain control of your own career by doing these. Those extra works make you a better software engineer. An accomplished software engineer write his/her own ticket. You will name the next project you want to work on. Opportunities will come knocking on your door.

Lastly, wherever you look, there are bugs to be fixed and source code to be read. Pick an area of interest, read the source code, try to fix few bugs that seems trivial, talk to the owner of the code and ask him/her to review or integrate what you have done. They will appreciate it and you get the experience. This is the power of Sun's openness. Don't squander.
Train yourself.

Mr. China: A Memoir

Mr. China: A Memoir

Tim Clissold


ISBN: 0060761407

Pub. Date: February 2006

Publisher: HarperCollins Publishers

What do you expect?

Tim and his partner, Pat, made few hundred investments each thousands times the average annual income of an individual. They did it all over China, from the bitter-cold north-eastern corner to deep valleys of the west. They did it without any clues on how the legal system works, not knowing how businesses were conducted, without trusted local consultation, without good command on Chinese language, without any check and balance mechanism, without reliable monitoring processes. They inspect their investments once in few months, or until a crisis emerges.

He lost few deals to “creative operatives.” Duh!

The book provides good entertainments. Tim's description on BaiJiu (white liquor) is hilarious. I really felt for him during the heart-attack episode. His realization of China will always pursue its “chosen path” was right on. “The civilization has always endured temporary invasions and eventually absorbed the invaders.” Sometime it took a couple of hundred years and that's OK.

But as a business book, it is a yawn. When I talked to a smart venture investor in San Francisco, she was cautious, “Everyone investing in China does not make me. I need to make sure I can get good return before I pour any money into anything.” The lessons Tim learned have been learned for generations. That they also apply to China is not really novelty.

Guns, Germs and Steel

Guns, Germs and Steel: The Fates of Human Societies


Jarred Diamond


ISBN: 0393317552

Pub. Date: April 1999

Publisher: Norton, W. W. & Company, Inc.

History is never the same again. Now I think of history geographically. The book, recommended by James Gosling and Bill Gates, tried to answer a daring question, “Why is the world today dominated by Eurasian descendants, instead of Australian, Native American, or African?” Jarred Diamond refused to accept the common and obvious answer that people from the Eurasia continent are genetically superior. All people are intellectually about the same, he has observed that first-handedly. There must be a different answer.

This is where you should stop reading, unless you don't mind me ruining the book.


Homo Sapien started from Africa and Eurasia. After many thousands of years, they migrated to America and Australia. When they came to the new continents, they quickly hunted all big mammals to extinction. Those mammals never saw human before and therefore defenseless. We human were more than happy to digest the protein.

Back in Eurasia, specifically around the Fertile Crescent and China, people started to develop agriculture. That changed the society to sedentary, from nomadic. Agriculture was more effective in food yield. Domesticated animals provided milk, meat, and energy other than human muscle. Population and density both increased. Technology, civilization, and political structure developed. Germs from animals jumped to human and people developed resistance to them.

But the diffusion of those advances encountered natural barriers in America and Africa. These two continents were delayed by more than 10,000 years in terms of food production technology and other progresses that come with it. Around 500 years ago, the clash happened when Eurasian developed modern ocean capable transportation.

Jarred claimed that germs Eurasian brought over killed more native Americans and Aboriginal Australian than guns. Historical records show that common germs wiping out whole native American and Aboriginal Australian tribes. Their populations reduced to a fraction of that before the encounter and the continents are now entirely dominated by Erasmus.

The most controversial chapter is the epilogue. Jarred speculated the reasons why China is less dominant than western Europeans. In that chapter, he observed something very unique about Chinese — it is the only old continental culture that remained unified for over 3000 years. Not even USA enjoys the same consistency in language and political unity. For thousands of years, China has been centrally governed. For this reason, it enjoyed centuries of leading position in technology and innovation. But since about 500 years ago, the unity reared its ugly side. A single government can stop or reverse the progress much easier than a diverse one. China stopped ocean exploration in 1500 A.D. and missed the opportunity to colonize America. European came few hundred years later and profited handsomely. Similarly, China stopped metallurgy, guns, rocket, clock, water-powered mills, etc. The diversity of Europe slowed down its innovations but also provided more venues for them to survive. Columbus, for example, tried many kingdoms before being funded by Spain. If he was in China, there will be no 2nd chance for him.


Is history predictor for future? Is so, what has Jarred taught governments and corporations today?

How exciting.

What crime the iron committed?

Yue Fei (岳飛, 1103-1141), was my hero. He is the epitome of poignancy in China history. So, so sad. So, so maddening. I blogged about a poem he wrote earlier.

Around 1200 A.D., Han people under Song dynasty (宋) was invaded by Mongolians. Song was among the worse dynasty in China history. Most emperors were weak and corrupted. No wonder Mongolians thought great opportunity to grab the fertile middle kingdom.

YueFeiTomb
Yue was a great general. His troops won battles again and again. It looks as if the dynasty had a chance to fight back and send those barbarians home. Alas Mongolians are not stupid. If they cannot win by force, they go the alternative method that has proven to work everytime — find an insider. They don't even need to try bribe this time. The prime minister, 秦檜 (QinKuai), believed in negotiating with the enemy. Mongolians' position was clear, no negotiation if Yue is in power.

But Yue was winning. That's very inconvenient for Qin.

He sent 12 “Emergency Executive Order” from the emperor to summon Yue back from the battlefield. Yue wanted to stay and command the troops, but felt he must obey the orders from the emperor. He came back and got arrested immediately. When challenged which crime he committed, Qin's answer became the most famous one, “There needs not be a reason” (莫須有, MoXuYou). Soon, Yue was tortured, sentenced, and killed.

One of the guard stole his body and buried him in a secret location. 21 years later, the new emperor realized how horrendous the mistake was. He gave a large reward to the guard and re-buried Yue, properly this time, next to West Lake, in the city of HanZhou. He also bestowed honorific title for Yue. Too bad that Yue's son was long dead from the battle. The tomb was first built in 1221 and maintained few times later. The last major maintenance was in 1979.

QinKuai
The tomb featured, very interestingly, the iron statues of Qin and his wife kneeling in front of Yue's tomb. It was the punishment for what they did. Over the thousands of year, the statues were destroyed and rebuilt many, many times by people kicking, bashing, spitting, and urinating on them. Finally, the government fenced them off and put up a sign to plead people not to.

Gate
There are two lines of rhythms on the gate of the tomb.

青山有幸埋忠骨,白铁无辜铸奸臣

Roughly, “The hills are lucky to harbor loyal bones. What crime the iron committed to be formed in the shapes of traitors?”


epilogue:

Song dynasty went steady downhill after Yue's death. They moved the capital south to near HanZhou, from near Xi'An. Lasted few more decades and was conquered by Mongolians who started the Yuan dynasty.

Defining Moments

Defining Moments January 12th, 2006

Career progresses not linearly. After few years, you have become proficient with your job, how does it go from here? Where do you break out from this current path?

Corporate ladder is more like a pyramid. There are fewer and fewer positions as you move up. With each rung, there are only a fraction of people who will advance. How would you be the one that get chosen? More importantly, how is the selection done? Without knowing the rules of the game, how is it possible for you to win?

I frequently tell the old Chinese folklore of waiting for the rabbit (守株待兔).

There was a farmer who was resting under a tree after a long morning's work. A rabbit dashed through and crashed into him. The farmer was pleasantly surprised. This made up more than the rest of the work. He took the rabbit and enjoyed the meal.
The next day, the farmer chose to wait under the tree for another rabbit. It did not come. But the farmer kept on waiting, day after day.

Imagine you are one of a group of farmers waiting for rabbits. There is a luck element here. If it ran the other way, someone else will get it. You will just keep on waiting.

If, however, the rabbit comes your way, are you skilled enough to capture it? Are you nimble enough? Do you design traps? Do you work with the ones next to you to optimize the chances for both of you?

First thing a manager must do is get better with what he does. Everyday, think how can you do better, what skills do you need to acquire, and who can do it with you? There are few basic skills every manager must have. Review them. Ask a mentor to give you candid feedbacks.

And when the rabbit comes, what I call the defining moment, are you sure you know what it looks like? Surprisingly, a promotion opportunity is not that recognizable. You should train to recognize them.

Most common opportunities come in the form of a resignation. A peer or someone a level higher quit. That causes the organization to shift. This means you can benefit from it. Obviously, it will be much better if you learned about the departure ahead of the time. A good resignation is done secretly. Very few people will know about it. But the big boss is always in the knows. He either has a plan or will need a plan quickly. You may be just what he needs. But your timing must be perfect so that he can plan with you as an element.

Second form is a reorganization. Companies today must be agile to deal with the dynamics of the market. As the result, they re-align their resources to enhance the chance of achieving the goals. Since the market changes frequently, the goals, short- and long-term ones, shift priorities. Re-org is when new priorities are recognized officially. What exactly are the new priorities now? How would your skills be applied, differently, now? Make that known to the decision makers so that your skills can be better utilized.

Expansion is clearly the easiest one to recognize. But getting promotion from it always comes with a price. All major expansions begin with some studies, but not all studies lead to real, funded expansion. Those who contributed the studies, investigation, or prototyping are frequently tapped to participate the expansion project when it is funded. Why are you not there on “ground zero?” Two possibilities: your skills were not required in the early stage or you did not show willingness to contribute without assured return.

Downsizing is such a dreaded word that few recognize its benefits. If done properly, downsizing can be great career opportunities. Downsizing means the cancellation of projects that are large enough to meet the financial target. The surviving groups usually end up with slightly more resources, therefore, it is actually expansion for them. Again, if you are skilled, there is nothing to worry about.

Build your skills relentlessly, answer the door when opportunity knocks. It hurts when the rabbit comes and you are not ready. It hurts even more when someone captured a herd of geese and you did not even know what is a net.

First Snow


Let it snow, let it snow, let it snow. I am giddy like a kid. Not many times in my life snow flakes fall where I can reach.

Clearly snow removal equipment is not a familar concept here. People try to clear away the snow with the most basic tool – sweeper. These two guys have been sweeping the same pathway for half an hour when I took the picture. When they reach the end, they walk back to the beginning and start again.

Like all cities that experience snow less than 10 times a year, Beijing is paralyzed. In 45 minutes, I advanced less than a mile on the highway and passed 2 accidents. When the radio reported 30 accidents in the hour started from 8:30am, I decided to turn back work from home today. Not that I may get into an accident myself, I won't reach office before noon at this speed.

Working remotely with a VPN connection and attending “meetings” over phone forwarded to my cell, I certainly realized, “This is not much different from in California.” In fact, without looking out the window, this feels pretty at home.

World is Flat and Moneyball

I am the least smart person in the family and proud of it.

Both daughters are bright, smart, intelligent, personable, and, I am unbiased saying this, drop-dead pretty.
They read in very different styles. Younger one “binge read.” She attacks a book by burying in it. Older one used to read with a computer on her side. When we were in Lake Tahoe, I noticed that she no longer. Instead, she scribbled on this blank paper bookmark once in a while.

I now hold a pen when I read. But I just scribble on the title page when something triggered a thought.


The World Is Flat: A Brief History of the Twenty-First Century


Thomas L. Friedman

ISBN: 0374292884

Pub. Date: April 2005

Publisher: Farrar, Straus and Giroux

Honestly, right after China Inc., I did not want to read another book on globalization. But Vijay gave us each a copy when we were in Bangalore.
I binged it on the flights to US. Hey, if there is one thing this business travel is good for. I read a lot more now.

“Vanilla just won't put food on the table anymore,” Tom Friedman tried waking up Americans. “You have to offer something totally unique.” In this flattened world, everyone competes globally. Whatever you have that was good enough for the village, town, city, state, or even country. It is no longer. It must be the best, or most unique, in the world. Tom Friedman told a story of China selling Virgin of Guadalupe statuette in Mexico. It is not exactly a high-cost country, it has a huge distance advantage, and the statuette is it's own patron saint. Yet China has taken over this market by simply making the statuettes better and cheaper.

“Would Americans wake up,” I thought when I finished the book on the flight back to Beijing. “No.” IT professionals, just like auto workers in the mid-80's, are in deep denial. Instead of upgrading their skills, they spend the precious time protecting their “ways of life” and pretending their jobs cannot possibly be offshored.

Tom put it clearly. There are only 4 untouchables who cannot be offshored: special, specialized, anchored, and adaptive. Honestly, for us “normal” people, the only hope is to be adaptive. This means the way of life of getting a job after a technical degree and enjoy football over beers every weekend is no more. To survive, one must be upgrading himself constantly. Never rest, always embrace changes. It does not matter one likes this new lifestyle or not. There are billions of people over there doing exactly that. They don't mind drinking your beers, when they take over your job. Detroit has proven, unionization does not work. You compete or the factory closes. The way of life is gone.

That just does not sound American. Does it?


Moneyball: The Art of Winning an Unfair Game


Michael Lewis

ISBN: 0393324818

Pub. Date: April 2004

Publisher: Norton, W. W. & Company, Inc.

Moneyball is a much lighter book. It is my first ever on baseball and I learned a lot.

Major League Baseball (MLB) is a complicated sport with a very rich history. The heart of the game is the players who entered the feeder system via high-school or college drafts. The new entrants to the system go into the minor league where they are paid meagerly and watched all the time.

Once they are considered good enough. They are brought up to the “big game” where fame and money shower on them. The system is ruthless. When the talent is no longer needed, or not good enough, the player will be dropped back to the minor leaque or traded away.

Michael Lewis depicts the strange and arcane system most teams use to evaluate the players. As a contrast, Oakland A's general manager, Billy Beane, does it differently. Gosh, he was scientific. The revolutionary general manager that has a vision and the intensity to change. Clearly, he also enjoys autonomy from the owner to run the team his way, as long as he keeps on winning.

Billy Beane has a system that gives each player an “expected score per dollar” evaluation. Simply put, the objective is to win. To win a game, you must score. For baseball, scoring is a mixture of luck and player talents. If there exists a system to give the expected score of a player, per game, you can then compute the expected score of the game, given the totality of all players. Statistically, if you have enough “runs” (baseball's term on scoring), you are likely to win.

Beane's system is complicated, since players have positions in defense and try to slug when they are at bat. The system must evaluate both defensive skills and offensive ones. It is further constrained by the budget allocated by the owner. The general manager's job then becomes running a complicated linear optimization — win enough games to enter playoff with the least amount of money. Billy Beane is so good that he routinely beats other teams that have much larger budget.

Strangely, this is more a management book than baseball. I read Michael Liewis's Liar's Poker years ago. This one is as much a pager turner.
