Abstract:

One lesson we've learned over the past several years here at Cooper is that on the vast majority of our projects, intimate client collaboration is a critical ingredient for success. This is a lesson that we have sometimes learned the hard way; collaboration can be messy, unpredictable and has often forced us to compromise what we thought was a supremely clear and elegant vision.
