Waterfall-model
Question 1 |
The major shortcoming of waterfall model is
The difficulty in accommodating changes after requirement analysis. | |
The difficult in accommodating changes after feasibility analysis. | |
The system testing | |
The maintenance of system. |
Question 1 Explanation:
Advantages:
1. Waterfall model is simple and easy to understand.
2. It works as reference model for others.
Disadvantage:
1. Real projects cannot be sequential
2. Initially all requirements should known i.e requirements are frozen. It may be suited for static projects.
3. Error omission too costly
4. Maintenance is too costly(We have to redesign the whole project from scratch)
5. Customer must have patience
6. It is based on Big-Bang approach
