Answer Key

Proof-of-Concept, Prototype and Product

Section A: Quick Questions

B — True

B — Proof-of-concept

A — False

A — Product

A — True

Section B: Match the Pairs

Proof-of-concept → A small test used to prove an idea is technically possible

Prototype → A working model used to demonstrate and test how a solution works

The final, polished solution ready for real-world use → Product

The stage that comes first, testing only feasibility → Proof-of-concept

The team skipped straight to building a full product without testing feasibility first → A proof-of-concept should be used first to confirm the idea is possible

A rough prototype was sold directly to customers as the finished product → A product should be fully developed and tested before release, unlike a prototype

Section C: Definitions

Proof-of-concept, Prototype, Product — Three progressive stages of solution development: proof-of-concept tests feasibility, prototype demonstrates function, and product is the final polished release

Section D: Fill in the Blanks

A proof-of-concept tests feasibility first

A prototype
 demonstrates how the solution works

Section E: Spot the Error

A — A product is the final stage of development, not the first — a proof-of-concept comes first.

A — Proof-of-concepts come before prototypes, not after them.

B — A proof-of-concept is minimal and not polished — that describes the product stage instead.

B — A prototype can and should be tested and changed based on feedback.

C — Testing feasibility of one idea describes a proof-of-concept, not a product.
