Final answer:
1. Prototyping The spiral design process involves iterative rounds of development, prototyping, user testing and refinement based on feedback, making it the model known for releasing multiple beta versions to solicit user feedback.
Step-by-step explanation:
The software development model that releases multiple beta versions and solicits frequent user feedback is known as the spiral design process. In this iterative process, designs are developed, prototyped, evaluated, and then refined based on testing results and user feedback.
This is essential for understanding the strengths and weaknesses of the design, and making adjustments accordingly to improve the quality of the final product.
Prototyping is a crucial step in this process, where a trial working model, or prototype, is built to test design decisions and identify potential problems. User feedback is specifically relevant here, as it can highlight real-world usage issues that may not be apparent to the design team.
Through multiple iterations of this cycles involving prototyping and user testing, the design gradually evolves, with enhancements being made in line with user requirements and feedback until the design meets all constraints and performs acceptably, at which point the product can be finalized for deployment.
