In this lesson, you review the overall factors that can affect an Office 365 deployment. However, it is important to realize that these are not necessarily complete deployment blockers, merely factors about which you need to be aware. This is the strength of the FastTrack process—your customers can take it as far as they want and can reach a deployment position where they realize value from the Office 365 platform without affecting their existing infrastructure or compromising on the benefits of the cloud based service.
