What are the differences between extreme programming XP and Scrum methodologies?
XP teams typically work in iterations that are one or two weeks long. Scrum teams do not allow changes into their sprints. Extreme Programming teams work in a strict priority order. Features to be developed are prioritized by the customer (Scrum’s Product Owner) and the team is required to work on them in that order.
What makes extreme programming different than scrum?
Extreme programming is a software development methodology, the goal of which is to satisfy the customer by delivering high-quality, valuable software at small intervals. Scrum is a framework for sustainably developing complex products, and you can use it with products other than software.

What are advantages and disadvantages of the waterfall model?
Advantages and Disadvantages of Waterfall Model
| Advantages | Dis-Advantages |
|---|---|
| Before the next phase of development, each phase must be completed | Error can be fixed only during the phase |
| Suited for smaller projects where requirements are well defined | It is not desirable for complex project where requirement changes frequently |
