In software development, there are two main models. These are the waterfall model and the iterative model. The waterfall model is a sequential process where one person designs software before handing it to another person who then builds on top of what was done before. This is the most common form of development, but it is also considered to be slow and inefficient. The iterative model is an incremental process where one person designs software and then hands it off to someone else who builds on top of what was done before with no limitations on how many times they can build upon it. This method is faster and more efficient than the waterfall method, but it can also lead to user frustration as they will not always see changes or improvements in their product right away.
