• Chose B4

  The key difference between Agile vs. Waterfall is that Waterfall breaks down software development into isolated phases that flow into each other, while Agile advocates iterative development cycles in which multiple lifecycle phases can run in parallel.

  Option A, "Waterfall increases agility to implement faster while Agile promotes reliability," is incorrect. Both the Waterfall and Agile methods can be used to deliver software quickly, and both methods can be used to deliver reliable software. Option B, "A phase begins after the previous phase has ended in Waterfall while Agile phases run in parallel," is also incorrect. In both the Waterfall and Agile methods, phases of the development process may be carried out in parallel. Option D, "Requirements can be updated in Waterfall while in Agile it should be gathered in the beginning," is also incorrect. In both the Waterfall and Agile methods, requirements can be updated as the development process progresses. However, the Agile method places more emphasis on gathering requirements at the beginning of the project and being responsive to changing requirements throughout the development process.
