What Rapid Development is not? u It isn't Rapid Development™ —a magic phrase or buzzword u It isn't a glitzy Blaze-O-Matic® or Gung-HO-OO™ rapid-development methodology 7
What is Rapid Development? u It is a generic term that means "speedy development" or "shorter schedules" u It means developing software faster than you do now 8
Quotes u I wish I had a simple solution to the development-speed problem. I also wish I had five million dollars. But simple solutions tend to work only for simple problems, and software development isn't a simple problem. Rapid development of software is even less simple. (Steve Mc. Connell) u For every complex problem, there is an answer that is short, simple, and wrong. (H. L. Mencken) 9
