8. Ben Coleman, one of your systems analysis team members, surprises you by asserting that when a system uses a test for correct field length, it is redundant also to include a test for range or reasonableness. In a paragraph, give an example that demonstrates that Ben is mistaken on this one.

What will be an ideal response?

The team member does not have a clear idea about how to install an input test routine. Seven input validation methods are not mutually exclusive. Rather, by combining two or more methods, systems analysts may expect more accurate input. In a given example, if you install only a field length test, you cannot detect out-of-range input. By the same token, if you install only a range test routine, you cannot detect input with the wrong record length.
