The biggest risk is the creation of system unsatisfying customer requirements. Therefore, functional and applied software certification tests, stress testing, usability testing, and security testing and others are required to avoid such a situation.

Early detection of primary mistakes in design allows reducing the risk of faulty software delivery. Introducing of design changes involves interactions between modules, user interface control, etc. Attempts to correct design mistakes at last development stages or while delivering the system to the customer can lead to non-fulfillment of delivery terms of the project, or even to non-operability of the system.
