Final answer:
No, when a system fails to deliver required functions, it is not necessarily because the customer changes requirements.
Step-by-step explanation:
False
When a system fails to deliver required functions, it is not necessarily because the customer changes requirements. There can be various reasons for a system failing to meet customer needs, such as technical limitations, inadequate planning, poor design decisions, or errors in the development process.
For example, if a software system fails to perform a specific function, it might be due to a bug or coding error, rather than a change in customer requirements.
