Cooper's Steve Calde has a nice overview article entitled "Design Research: Why you need it." An excerpt:
A design research phase consists of three main activities: stakeholder interviews, domain research, and user interviews. Some combination of all three makes for a successful phase. The length of each activity depends on the complexity of the product. More is always better, but effective design research can be gathered in a relatively short amount of time.
