Suppose a 400-kilometer relay is performed by 400 runners where
everyone runs a single kilometer. Say that the
mean time for each runner is 5 minutes with a standard deviation of
30 seconds. Use the normal approximation to
calculate the probability that this rally will last at least 33
hours and 45 minutes (You may use the symbol Io in your
answer.)

How can we assess whether a project is a success or a failure? This case presents two phases of a large business transformation project involving the implementation of an ERP system with the aim of creating an integrated company. The case illustrates some of the challenges associated with integration. It also presents the obstacles facing companies that undertake projects involving large information technology projects.
