For certain types of projects it's possible to accelerate delivery by using a "follow the sun" model where at the end of the workday each team hands off tasks to another team farther west. This will obviously decrease productivity per team member due to additional communication overhead and increase the risk of errors, but the trade-offs can be acceptable if the project has to hit a fixed external deadline. Doing this successfully requires a high level of project management discipline that most organizations lack.
