group developing
We have a team of 4 **asp.net** developers. we are developing a web application. but we don't have   exprience in group developing.  
So the first question is that can you suggest some tips for group working?  
And the second one:We decided to use three layer architecture pattern. but we don't know whether to develop each  layer completly and then start to develop another layer? or for eact functional requirement   develop all of the layers together?
