What is the characteristic of spiral development acquisition strategy?

The characteristic of the spiral development acquisition strategy centers on the notion that requirements are not fully defined at the start and can evolve over time. This approach is particularly beneficial in complex projects where initial requirements can change as technology matures and new insights are gained during the development process.

In spiral development, the project is often broken down into iterations or "spirals," where each iteration allows for refining and adapting the project's goals based on the results of previous cycles. This iterative nature enables teams to incorporate feedback and lessons learned, ensuring that the final product better meets the needs of users and stakeholders.

This strategy contrasts with approaches that require a fully defined set of requirements from the beginning or those that aim to deliver all developments in one comprehensive effort. By allowing for flexibility and adaptation, the spiral development strategy supports innovation and improved alignment with evolving technological capabilities and user needs.
