Agile Development more gyaan

I couldn't resist from linking to an article on Agile which I came across while browsing titled,
Secret To Software Success

Frankly What I feel is that this one is a must read for all those involved in SDLC process.
Some excerpts from that article,

1. Why Building Software Is Not Like Building a Bridge
2. If this were the pharmaceutical industry, we'd be killing people,"
3. Desperate to avoid the scapegoat's horns, some technology executives are finally beginning to take up arms against this sea of failure, redefining how software is built. They call it Agile Development, a disciplined, minimalist approach that's both elegant and arduous, and maybe IT's best hope to avoid "Yet Another Trip to Hell."
4. Build on success, not hope. As often as once a week, and not less than once a month, complete a piece of software. Then have your business deciders test and approve it.
5. Think of it as climbing Mount Everest. Do you set a plan and say, 'On day seven we'll be here and the weather will be this and I'll need my ice pick'? You can't do that
