Also, a real agile development cycle started from OO design, you need to design the code well enough that each object is relatively isolate from each other before we can talk about Agile.

nowadays, every organization talk about agile development cycle, but few business ppl really spend time to understand what it is, and how much it is involved.

like one of the poster here said, "Agile waterfall"

Well that is one approach and it sometimes works. But usually it fails or least forces excessive rework because much of what you thought you knew at the beginning of the project later turns out to be incorrect. Another more agile approach is to avoid big up front design. Treat design as an emergent property and keep the internal OO design clean through constant refactoring.
