Question:

"
Respond in 3-6 concise sentences. A business student has sold 10,000 preorders
for a non-existent science-fiction minecraft clone called LaserCraft and now
needs to actually build it. Due to your team's reputed expertise in this
area, you have been contracted to develop the user-management web service for
the game's online features. 
What level of fidelity will you target for your initial implementation? Why?
What application architecture will your initial implementation have? Why?
"

Marking criteria:

5 criteria:
1. Choose between proof of concept, prototype, and minimum viable product. Also acceptable is low/medium/high fidelity.
2. Provide a rational justification for choosing that fidelity level. 
3. Choose one of the discussed application architectures (2-tier, 3-tier, service-oriented, microservice).
4. Provide a rational justification for choosing that architecture.
5. Your response should be concise and direct.

A solution that would obtain full marks:

We will target a medium-fidelity prototype, because there is already market validation for the game, but requirements for the user management service still have to be validated. We will use a 2-tier architecture for its simplicity, to maximize development speed. If scalability proves an issue, the next implementation can use a different architecture.

Another solution that would obtain full marks:

We will make a low-fidelity proof of concept. User management is not a core function of the game, so we know nothing about the technical or market feasibility of its requirements. It would be best to make a proof of concept and solicit feedback before committing to a full initial implementation. The proof of concept will have a 2-tier architecture for simplicity, since the benefits of the more complex architectures are lost on a low-fidelity implementation.
