Expert Solution & Answer
Chapter 4, Problem 4.3RQ
Explanation of Solution
Prototype:
Prototype is an early approximation of the final product. It sometimes implemented for users for review and it is easier to understand and evaluate than data models. The software prototyping process is categorized into four ways is as follows:
- Determining initial requirements
- Implement initial prototype
- Review
- Revise
Determining initial requirements:
The process of identifying initial requirements from user is to decide the software process.
Implement initial prototype:
It is a design phase of the system. It looks like a simple drawing on whiteboard that elaborate the working model...
