Requirements Shell / Prototyping

I need one paragraph for each discussion and no references are need.

Week 7 Discussion 1

“Requirements Shell” Please respond to the following:

  • Functional requirements capture what a product should do. Environmental requirements refer to the circumstances in which an interactive product will operate. Think of some cases in which the functional requirements contradict environmental requirements and give examples of how the contradiction occurs.
  • From the e-Activity, compare and contrast the usability and effectiveness of the Volere Requirements Shell and the RESCUE Requirements Shell. Identify which of these shells you would use together and why.

Week 7 Discussion 2

“Prototyping” Please respond to the following:

  • Low-fidelity prototypes are mainly used to conduct research on a product and are not integrated into the final product, while high-fidelity prototypes may evolve into a final product. Compare and contrast the final product that evolves from a high-fidelity product and a product built from the ground up after studying and learning from a low-fidelity prototype.
  • Compare and contrast the design process of a cell phone interface using paper prototyping versus a tool such as Microsoft Visio, open source wireframing or mockup tools. Identify which method you would prefer to use, and why
