Read the first 7 Rapid Prototyping & MVP Development flashcards as text

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

    Answer: Foam or cardboard physical mock-ups

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

  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?

    Answer: 5

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

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

    Answer: Pre-sell / presale MVP

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

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

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

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

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

    Answer: Minimizing the time to validated learning

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

  6. A team releases an MVP only to a small group of hand-picked early users before a broader launch. This strategy is called:

    Answer: A closed beta / soft launch

    A closed beta invites a curated group of early adopters to provide feedback, allowing the team to refine the product before wider exposure.

  7. Which principle of the Agile Manifesto MOST directly supports rapid prototyping practices?

    Answer: Delivering working software frequently, in shorter timescales

    Agile's emphasis on frequent delivery of working software aligns directly with rapid prototyping's goal of getting tangible artifacts in front of users quickly.
