gang bang - The Jargon File

The use of large numbers of loosely coupled programmers in an attempt to wedge a great many features into a product in a short time. Though there have been memorable gang bangs (e.g., that over-the-weekend assembler port mentioned in Steven Levy's Hackers), and large numbers of loosely-coupled programmers operating in bazaar mode can do very useful work when they're not on a deadline, most are perpetrated by large companies trying to meet unrealistic deadlines; the inevitable result is enormous buggy masses of code entirely lacking in orthogonality. When market-driven managers make a list of all the features the competition has and assign one programmer to implement each, the probability of maintaining a coherent (or even functional) design goes to epsilon.
