Final answer:
The two kinds of requirements that are discovered from the user story perspective are functional and non-functional requirements, which guide the development, prototyping, and evaluation of a solution.
Step-by-step explanation:
The two kinds of requirements which are discovered from the user story perspective are:
- Functional requirements
- Non-functional requirements
Functional requirements define what the system should do, while non-functional requirements specify how the system should behave and impose constraints on the design and implementation, such as performance, usability, and security. Requirements and constraints play a significant role in the design process. Requirements might include specific needs like the purity of water or the lifetime of a designed system, while constraints might refer to budget limitations or environmental considerations. These drive the development of a problem statement, which then informs the ideation, prototyping, and testing phases of a solution.
