Interestingly Jared M. Spool waxed on recently about slowing down and changing the design process, from one large change to just hundreds of small testable alterations. Now this is nothing really that new.
In the early days of the web (1995 to 1997) I remember it was all about making small changes, validating them.
You know the drill make small changes, implement, test response, respond to test. These can be from changing a typeface, moving a heading, changing the location and size of a button.
