Metaphors between

Metaphors between engineering in its traditional forms and software engineering are often used to argue for or against the maturity of the industry. I agree that we don't have the several hundred years of experience that went into the development of civil engineering practices, and even the civil engineers are occasionally defeated by "the user". The recent levee failures in the USA as a result of flooding weren't engineering failures: the flood levels were simply higher than their design could cope with. The user, presumably, decided that the cost of handling a "hundred-year event" flood too high.

Given the parallels and your comments however, I'd be interested to know what you think of the extreme programming "do the simplest thing that could possibly work" mantra and the shunning of "big up-front design". Extreme programming is a way of maintaining forward progress, but it's less likely to result in engineering standards. In short, everyone might end up with their own individual railway gauge. What's your opinion?

PS: Your blog's extraction of a title from the front of a comment isn't terribly meaningful, in preview at least.

AISO founders envisioned a Web hosting company that was environmentally friendly. While the company employed energy-efficient innovations like solar panels, its infrastructure produced unacceptable power and cooling requirements. Find out how AISO leveraged AMD technology to overcome their challenge in this case study white paper.

In this whitepaper, Scalar explores the opportunity to change the landscape with respect to mission critical databases built around Oracle. Leveraging technologies such as Linux, high-end commodity processing power and Oracle RAC technology to architect, design, build and maintain database infrastructure that delivers maximum availability, reliability and performance at a fraction of traditional cost.

On a typical day, weather.com, the Web site for The Weather Channel in Atlanta, serves up between 15 million and 20 million page views. But in September 2004, when back-to-back hurricanes ransacked Florida, the peak traffic on one day more than tripled: over 70 million page views by more than 7 million unique visitors. Read the full success story now.
