Look in the literature for examples of success and failure of international projects.
Here is a list of international projects. Try to uncover why these were successes and failures.
The Aswan Dam in Egypt;
The merger of Chrysler and Daimler-Benz;
Mergers of wineries around the world.
Use the above examples and others to start building a list of factors that lead to failure or success.
Try applying the international score card to a specific project. You will have to make some assumptions and do some thinking since you will obviously not have all of the data.
