Then they find they've lost, not gained, flexibility by being tied into a long-term lease in an unsuitable building. Site location consultants can be a useful resource since they tend to remain objective. Try to avoid moves during the summer months. You will be competing for scarce moving equipment, supplies and vehicles. Get everything in writing, whether it relates to the move or conditions at the new site.
International relocation is particularly tricky.
If you can, consult with other firms who have made a similar move. Just remember that they may not admit to poor judgement and that misery loves company. International consultants are a good resource, as are your own country's ambassadors and trade representatives abroad. A list of sources who can help you relocate will soon be available here. Editorial contributions and ideas for the Project-Manager site are encouraged from practitioners and experts, in all areas of project management.
