The user interface design developed by the designer does not account for proper support for disabled users. The cause of this situation is the designer's fatigue. The programmer implemented the user interface according to the design, but due to time pressure, did not include proper exception handling in the code for calculating bonuses. After the system was deployed in the operational environment, some disabled users reported issues with the interface, and the relevant authority imposed a financial penalty on the company. No one noticed that sometimes the bonus amount is calculated incorrectly.

Which of the following statements is CORRECT?
