Requirements focus on the solution; Designs focus on the need

Requirements focus on the "what"; Designs focus on the "how"

Requirements are for stakeholders; Designs are for developers

There is no functional difference in BABOK v3

Requirements focus on the "what"; Designs focus on the "how"

Classic BABOK distinction: Requirements = What; Design = How.
