Final answer:
The correct answer is B, which states that Waterfall teams finish one step completely before moving to the next, whereas Agile teams work in an iterative manner on different steps simultaneously. Option B is correct.
Step-by-step explanation:
Differences Between Waterfall and Agile Methods
The Waterfall and Agile methods are two different approaches to software development. The main difference lies in their structure and flexibility. Waterfall is a linear and sequential approach where each phase must be completed before the next one begins. Agile, on the other hand, is an iterative and incremental approach.
Waterfall Method
In the Waterfall model, software development is divided into discrete phases such as requirements, design, implementation, testing, deployment, and maintenance. Each of these phases follows the previous one in a sequential order, and typically, a phase must be fully completed and approved before moving on to the next. This approach can be likened to a waterfall, hence its name, where progress flows in one direction only, much like water.
Agile Method
The Agile model divides the project into small parts known as sprints. Each sprint is a cycle that includes planning, designing, coding, and testing, with the product being evaluated at the end of each sprint. This allows for adjustments to be made before the next sprint begins, enabling a more flexible and iterative design process. The Agile approach promotes collaboration among team members and stakeholders, as well as responding to changes quickly.
Answer to the Student's Question: The correct answer to the question is B. Waterfall project teams do not move on to the next step until the previous step is completed and approved, while agile teams interact to handle different steps of development simultaneously.
