Prototypes can be used to eliminate risk and facilitate communication by: a) Specific assumptions, dependencies or concepts are tested thus resulting in a better understanding of the system. b) Encourage end-user participation during all stages of development thereby largely reducing product uncertainty. c) The systems development process becomes clear to all stakeholders and tangible deliverables are produced on a continuing basis allowing for regular end-user assessment and testing. d) The iterative approach may identify possible risk areas early in the life cycle that will alert the project manager to apply risk management criteria to reduce the possible influence thereof on the project.
