A.Iterative design leads to project delays.

B.If iterative design is used; the customer will be less involved.

C.If the incremental approach is used, risks are detected at a later stage.

D.Iterations help to deal with uncertainties.

E.If incremental design is used; key functionality is considered as early as possible.

F.The iterative approach helps to detect design problems at an earlier stage.

A.Flexibility reduces testability

B.Increased efficiency results in reduced performance

C.Simplicity increases comprehensibly
