In fact, agile has been extremely successful.
It's the people that claim to "do agile" that invariably don't do it. But software development used to fail most of the time, and it doesn't do that anymore.
It used to fail once after a long time, now software fails a lot every 2 weeks.
They cloned one true scottsmann in the end..
If the idea does not compute with human nature, the idea is flawed, its basis the knowledge of human nature is non-existent and thus it had no place in reality after all..
Hmm that reminds me of what some people say about communism :)
Waterfall was also extremely successful.
People who failed just did it wrong. /s
What makes you say that it has been extremely successful? And when you say doesn't fail anymore, do you mean it doesn't go over budget and/or changes scope?
