Coder Be Agile Coder Be Quick

摘要

A new force is making itself felt in the world of software development. Advocates of the agile development methodology (www.agilealliance.com) claim that its potential to increase productivity in some areas is so bright that coders are going to need to wear shades to write software with it. Instead of starting by developing a detailed set of requirements, agile methodologies call for programmers to begin by writing small chunks of functionality that can be completed in two to four weeks — "iterations," in agilespeak. Module testing receives the same level of attention as the actual writing of the code. When one iteration is done, developers find the next requirement to add more functionality to the module just completed and thereby start a new iteration.
