A software development methodology is a formalized approach to implementing the Systems Development Life Cycle (SDLC). In other words, it is a list of steps and deliverables, and there are many different systems development methodologies. Each one is unique, based on the order and focus it places on each SDLC phase.
In this discussion post, you are required to explain the differences between an agile methodology (e.g., XP, Scrum) and Waterfall Development. What are the main differences? Where does each approach fit? What are the advantages and disadvantages of each?
The conventional Software Development Life Cycle has been used effectively in a number of recent system development projects (SDLC). This is the definition of the term "traditional." There are, however, certain drawbacks to this strategy to consider. What are the pros and cons of using an SDLC methodology?

Scenario
Pair programming is an agile software development technique in which two programmers work together at one work station. One types in code while the other reviews each line of code as it is typed in. The person typing is called the driver. The person reviewing the code is called the observer. The two programmers switch roles frequently (possibly every 30 minutes or less). Suppose that you are asked to build a system that allows Remote Pair Programming. That is, the system should allow the driver and the observer to be in remote locations, but both can view a single desktop in real-time. The driver should be able to edit code and the observer should be able to “point” to objects on the driver’s desktop. In addition, there should be a video chat facility to allow the programmers to communicate. The system should allow…

A user story specifies a feature that a user needs, while a test is an executable form of a user story and, as such, is directly connected to the user narrative that it describes. Early testing is critical in agile development. As part of the agile development process, it is recommended that acceptance tests be written for each user story before any code is written. Take a look at the following scenario using a university's Student Information System: A university student may use the system to register for courses and make payments online. Please submit at least FIVE user stories as part of the acceptance test for the aforementioned scenario.
