Question 5

difficulties with the waterfall approach

Answer 5

Demands for development resources are so numerous that AIS projects can be backlogged for several years.

A newly designed AIS does not always meet user needs.

The development process can take so long that the system no longer meets company needs.

Users are unable to specify their needs adequately.

Changes to the AIS are often difficult to make after requirements have been frozen into specifications.
