User-Interface Prototyping is usually successful. It will have many of the same risks as either Throwaway Prototyping or Evolutionary Prototyping, depending on whether you develop the user-interface prototype as a throwaway or as an evolutionary prototype.

For more details on the risks of Throwaway Prototyping, see Managing the Risks of Throwaway Prototyping, Managing the Risks of Throwaway Prototyping.
If you develop the user-interface prototype as a throwaway, beware of these risks:
Keeping a throwaway prototype
Inefficient use of prototyping time
Unrealistic schedule and budget expectations
CROSS-REFERENCE
For more details on the risks of Evolutionary Prototyping, see Managing the Risks of Evolutionary Prototyping, Managing the Risks of Evolutionary Prototyping.
If you develop the user-interface prototype as part of an evolutionary prototype, beware of these risks:
Unrealistic schedule and budget expectations
Diminished project control
Poor end-user or customer feedback
Poor product performance
Unrealistic performance expectations
Poor design
Poor maintainability
Feature creep
Inefficient use of prototyping time
