Over the years, I've read a lot of books on software engineering. Agile books in particular like to refute the "Waterfall Model". Every time I read about the Waterfall Model, I think to myself: I'm sure there must be companies out there that have tried this approach, but I have a hard time believing some software book would seriously propose it as the best way to write software. It must be the boogie man of software engineering methodologies. I was reading The Practice of Cloud System Administration: Designing and Operating Large Distributed Systems , and I came across this quote: Royce’s 1970 paper, which is credited with “inventing” the model, actually identifies it so Royce can criticize it and suggest improvements. He wrote it is “risky and invites failure” because “design iterations are never confined to the successive step.” What Royce suggests as an alternative is similar to what we now call Agile.
