Virtually any move is plagued by risk, and some won't be known until disaster strikes. The key to success is assessing known risks and planning appropriate countermeasures.
If you are moving products or processes to another location, you need to assess the complexity of the move, the business risks, and how to minimize those risks. You can measure the complexity of the move by ranking each of these 10 factors in terms of its complexity. Generally, if three or more factors are rated "high" in terms of complexity, you are dealing with a high-risk move that must be carefully planned and managed to ensure success.
