Zozee,
I am finishing up two school team projects and I can relate it to quilting too. With Uni projects I try on the first team meeting to discuss the teams strengths and weaknesses. It is surprising how resistant people are to this important first step.
When my guild does charity quilts or other group projects, I love to help with layout, ironing, making HST, trimming said HST, but not the sewing of the pieces to make the quilt. I am not a perfectionist, but I appreciate a quilt where the quilter has paid incredible attention to detail. I have been asked to take a top home to correct a mistake after it was pieced and I was happy to do that. We have people in our guild whose seaming is impeccable, it is best that they take care of that.
