Question 8

What does “iterative” mean?
What does “sequential” mean?


Iterative means repetitious.. In software development, iterative is used to describe a heuristic planning and development process where an application is developed in small sections called iterations. Each iteration is reviewed and critiqued by the software team and potential end-users; insights gained from the critique of an iteration are used to determine the next step in development. Data models or sequence diagrams, which are often used to map out iterations, keep track of what has been tried, approved, or discarded, and eventually serve as a kind of blueprint for the final product.


Sequence is the arrangement of things logically ordered.The things in the sequence has relationships with each other.A process may be sequential which means the steps of the process are related to each other and maintaining logically.
