Do you mean what do I think do doing the design and build work at the same time?
I think that it’s usually impractical to do both in parallel, but getting close to parallel is a huge advantage. I don’t necessarily advocate designing in the browser, but I definitely share my buddy Dan’s[1] sentiment of decide in the browser.
Get into the browser as soon as you can, whether you’re the designer and FED on the project, or even if those are two separate people. Having the design phase then the build phase only sets everyone up for disappointment.
If that wasn’t what you were asking, well, you can have that one for free! if you want to reword it then I’ll gladly take another stab at answering :)
