Miscommunication

I recently had some difficulties caused by poor communication in a group project. Just before spring break, we were presenting our final concepts for a library project we've been working on all semester. I was responsible for laser cutting a 1/16 scale model from plans made by another group member. The model was supposed to fit into a larger site model which was also built to a scale of 1/16"=1'. Taking the drawings made by a group member, I finished cutting and assembling the model right before the presentation deadline. Unfortunately, there was some misunderstanding about the required scale, resulting in a model which was ridiculously over-sized for the site model. The problem could have been easily avoided if we had discussed our plans more thoroughly as a group before taking action.
