6. In real life...
● Remove items from top or
bottom to fit your project scope.

will have different paths and
phases

7. Waterfall model
● Each group doing its
part

everything is correct

● Too strict

before starting the weeks worth of
next. analysis, design,

tests.
● Reiterate until project
is done.
