“We believe you should go back three times. You should do it with the people who are going to use the building six weeks before it opens, to record their expectations. That gives you a very interesting base. You should go back within the first six months, when they’re still fresh on the place and really feeling all the uneasy elements. Then you should go back about two years later, after they’ve accommodated themselves to the building. It would be wonderful to do a fourth one maybe ten years later, because by then the world has changed. Has your building been able to accommodate that change?”
