Which of the following is part of the incremental development model?

The incremental development model emphasizes the process of building a system in small, manageable pieces, or increments. Each increment represents a functional component of the system that can be developed, delivered, and utilized independently.

Iterative feedback is a foundational principle of the incremental model, as it allows teams to assess each increment upon completion, gather input, and refine subsequent increments based on that feedback. This feedback loop is crucial because it helps ensure that the evolving product is more closely aligned with user needs and expectations, ultimately resulting in a higher-quality software product.

In contrast, the other options focus on concepts not characteristic of the incremental development approach. A single release does not capture the essence of incremental development, which involves multiple releases or increments. Sequential phases imply a linear progression typically found in models like the waterfall model, which does not support the flexibility needed in incremental development. Comprehensive documentation suggests a focus on detailed records, which, while important, does not inherently relate to the incremental delivery of software functionality, where documentation is often lighter and more agile to keep pace with rapid changes.
