Oh, and that miracle is the extraordinary effort that we all put in when we are “down to the wire”, “4th and inches”, “when the going gets tough the tough get going”. Those last 3-4 weeks of 10-12 hour days 6-7 days a week, are the all too familiar project delivery death march. How big the miracle you need depends upon how much risk you have accepted throughout the delivery. The short cuts, the missed deliverable or milestone, lack of updated documentation, the missed impact assessment for scope changes and last minute design changes… all have risks that will impact the success of your delivery.
