Solution
The principal disadvantages of the waterfall development methodology are:
a. It minimizes changes to the requirements as the project proceeds: This is not necessarily a disadvantage. In fact, it can be seen as an advantage because it helps to maintain focus and avoid scope creep. However, it can become a disadvantage if the requirements need to change due to unforeseen circumstances or changes in the business environment.
b. A long time elapses between the completion of the system proposal and the delivery of the system and the design must be completely specified on paper before programming begins: This is a major disadvantage of the waterfall model. It can lead to delays in the project if the requirements are not clearly understood or if changes are needed. Additionally, it can be difficult to predict all the requirements at the beginning of the project, which can lead to problems later on.
c. The design must be completely specified on paper before programming begins: This is another major disadvantage. It can be difficult to fully specify the design before starting programming, especially for complex systems. This can lead to problems during the implementation phase if the design is not fully thought out.
d. It identifies system requirements long before programming begins: This is not necessarily a disadvantage. In fact, it can be seen as an advantage because it helps to clarify the scope of the project. However, it can become a disadvantage if the requirements change during the course of the project.

Consider the following two software development projects:X. Development of a conventional compiler for a well-known programming language (e.g., C, C++, Java) for a newly designed machine The project team is quite experienced in developing this kind of software.Y. Development of an application that manages the administrative activities of a doctor’s office. The project team is not very experienced with these kinds of projects and is expecting regular requirement changes during the product development. Which of these two projects is likely to better correspond to the Waterfall model, as it was originally proposed and why? Question 1Select one:a.Y is more suited for the Waterfall model because it's an administrative activities-based project.b.X is more suited for the Waterfall model because the original set of requirements is clear and the project team has experience in developing such projects.c.X is more suited for the Waterfall model because it's a programming language-based project.d.X and Y are both equally good candidates for applying a Waterfall process model.e.Y is more suited for the Waterfall model because this case requires adapting to regular changes in requirements throughout the development process.
