CPI Rapid Prototyping & MVP Development 5

Question 1

Which prototyping method is MOST appropriate when testing the physical ergonomics of a new hardware device at very low cost?

Accepted Answer

Foam or cardboard physical mock-ups

Answer

Foam or cardboard mock-ups let teams test grip, size, and form factor cheaply before committing to tooling or manufacturing.

Question 2

What is the recommended maximum number of participants for a usability test to uncover most major usability issues, according to Nielsen Norman Group research?

Accepted Answer

5

Answer

Research by Nielsen shows that five users reveal approximately 85% of usability problems, making larger samples inefficient in early prototype testing.

Question 3

An MVP that earns revenue from real customers before the full product is built is best classified as which type?

Accepted Answer

Pre-sell / presale MVP

Answer

A presale MVP validates both demand and willingness to pay by collecting real money before the product is completed, providing strong market validation.

Question 4

During a rapid prototyping session, 'diverge' and 'converge' phases refer to:

Accepted Answer

Generating many ideas broadly and then selecting the most promising ones to develop

Answer

Diverge phases encourage broad ideation without judgment, while converge phases involve evaluating and narrowing ideas to actionable prototypes.

Question 5

What does a 'Build-Measure-Learn' cycle prioritize above all else?

Accepted Answer

Minimizing the time to validated learning

Answer

The entire loop is optimized to reduce the time between forming a hypothesis and getting validated evidence that confirms or refutes it.
