"I think, really, that this is one reason that so many intelligent people drift away from baseball (when they come of age), that if you care about it at all you have to realize, as soon as you acquire a taste for independent thought, that a great portion of the sport's traditional knowledge is ridiculous hokum."

My sons have prompted me to read Moneyball by Michael Lewis. Anyone interested in baseball should find this a fascinating read. While contemplating Moneyball I found myself making comparisons between baseball and software development. The book tells the story of Bill James who began to statistically analyze baseball data and his results showed that there were skills that weren't recognized as having appropriate value. Value is considered in terms of what wins baseball games, contributions to runs. His efforts to convince the baseball establishment were met with stiff resistance. His message, although statistically sound and rational, was not synchronous with an irrational and stubborn baseball culture. I wondered whether the baseball phenomenon was similar to the resistance of the academic computer science culture to incorporate new proven methods, such as unit testing, into fundamental programming courses. This "we don't need no stinkin tests" culture leads to the creation of professionals who haven't been taught a very valuable skill that is sorely needed in the contemporary IT work place. A parallel example in baseball is that as youngsters, baseball players are not taught to be more selective about which pitches they swing at. Just as it has been shown that on base percentage is a more meaningful (in terms of contribution to runs) statistic than the batting average, we still announce a player's batting average when watching a televised baseball game. When was the last time you heard a baseball announcer tell the player's on-base percentage? We are a culture paying attention to statistics that focus on a less important aspect of the game. In software development, although it has been shown numerous times that unit-tested software increases ROI, our industry still suffers from >50% failure rates in large IT projects. Nevertheless, just as in baseball, we continue to go about these projects in the way the culture dictates instead of following proven practices. Even worse, we educate future programmers the same way we did fifty years ago. Isn't it time to re-evaluate how we are educating our future software developers?
Moneyball describes the development of the science of baseball to the point where people began to analyze the game from the perspective of derivatives in the stock market. However, to accomplish this, a better system was needed to analyze baseball events. For example, when a person hits a double in baseball, there are so many factors in play, that from an analytical perspective the term 'double' did not contribute enough information. An entirely new system was designed to analyze the events in baseball. The same is needed in software systems development and in the educational process at the undergraduate level.
