QUESTION 8

ITERATIVE: Iterative can be defined as a repetitive or recursive case that cycles until a case or an effect stop it. The aim of iteration is being able to find the problem even after progress is started or finished. Iteration gives the ability to person to go back easily and check the method step by step again and again. Hence, it has an important advantage over the waterfall diagram model which does not give the ability to turn back to steps of process.

SEQUENTIAL: Sequential can be defined as following each other in an order without any gap, consecutively or successively. If I try to correlate it to iterative, iterative spans all process and operations, but sequential spans only two operations and only the relation between them. Therefore, iterative and sequential have similar meanings but different extents.
