Recently, I presented alongside Michael Pappas of CII and Olivier Calas from McDermott International on a webinar that covered interface management benefits, implementation examples, and numbers on the results it can provide projects in terms of minimizing project cost growth. During the webinar we received numerous questions. We answered each person individually, but we also noticed some common themes developing in the types of questions being asked. We summarized some of our most asked questions into these themes and have shared the answers below. (If you are interested in the webinar, you can go to the webinar recording.)
