Murphy’s law says that if something can go wrong it will. This is why it is important to do scenario planning on your integration project.

One of the best tools in project management is Monte Carlo simulation, which will help you think about what can go wrong before, during, and especially after closing.

All kinds of random events can occur, and the pace and quantity of results can be ragged. Imagining plausible scenarios and plugging them in will improve your forecasting ability—and your management of change.
