The Quick and Dirty Software Development Life Cycle

I copied this from some programmer's blog. Unfortunately I couldn't remember where! I just had it saved to my Opera browser notes all this while.
Seems like a simple and straightforward plan. In other words...good! Can't wait to try this...

10: get the simplest case working.
20: get something twice as good working.
30: release to users
40: get something 5% better working.
50: goto 30

By the way, the syntax above reminds me of Applesoft BASIC. ie. My first love in programming!
