The waterfall method is characterized by a linear and sequential development approach where each phase must be completed before the next phase begins. This model emphasizes distinct objectives at each stage, making it easy to manage and follow because there is a clear progression from requirements gathering, design, implementation, testing, and deployment.

In the context of the waterfall method, once a phase is completed, it is typically not revisited, which means that changes or feedback loops are limited. This structure is particularly suitable for projects where the requirements are well-understood from the start and unlikely to change. By maintaining clarity and order through distinct objectives, teams can ensure that all necessary steps are taken in a logical order, reducing ambiguity and the potential for misunderstandings during the development process.

The other options focus on different methodologies. Iterative development with feedback loops, as described in another option, is characteristic of agile methodologies rather than waterfall. A focused approach on agile methodologies would not align with the waterfall's structured process. Lastly, while collaboration and cross-functionality are important in project management, the waterfall method does not typically involve multiple teams working together in a collaborative manner throughout all phases of a project; it is more rigid and structured in nature.
