Several years ago I watched a series of PBS specials about the development of the Boeing 777 airliner. Some searches on the internet found the title to be 21st Century Jet: The Building of the 777. It isn’t available on Amazon, but can apparently still be purchased from the Boeing Store. The film makers had an amazing amount of access as they filmed meetings, talked to engineers, suppliers, etc. It was a perfect case study in project management.
Boeing’s goal was to develop a long-range plane to fill a niche just below the capacity of a 747. With a 5-hour series the documentary was able to go into detail about certain issues (for instance the difficulty in getting a 2-engine aircraft certified for trans-ocean flights or how they test turbine blades). It was fascinating to watch the pieces come together. One way to save money was to do virtual testing of the engine instead of using a flying test platform. The engineers thought they wouldn’t even need to do the real-life tests because their models were so good. But the decision was made to do the test on a full-scale prototype anyway and on the first flight the engine flamed out (they used a 747 so they still had 3 other engines). The engineers went back and found a flaw in their computer model.
