Answer Key

Describing how a system satisfies a user's need

Section A: Quick Questions

B — User, need, feature, reason

A — The system helps because...

B — Mia has trouble reading small text. The app has a zoom feature, so the system helps because she can make words bigger.

A — The app has a read-aloud button.

A — The timer helps because it reminds Jo when to stop.

Section B: Match the Pairs

The system helps because... → A sentence starter that begins the reason part of a discussion

user, need, feature, reason → The four parts of a good discussion, in the right order

A full discussion that follows the right order → Mia needs to remember her homework. The reminder alert helps because it pops up on her tablet.

A reason that explains why a feature meets the need → The big text helps because Sam can read it without his glasses.

The reminder alert helps because it pops up. Mia needs to remember her homework. → The parts are in the wrong order. The feature and reason come before the user and need.

The app is good because it is fun. → It does not name the user, the need or the feature, so the reason does not link to a need.

Section C: Definitions

user, need, feature, reason — A good discussion names the user, then their need, then the feature that meets it, and ends with the reason it works. Starters like 'The system helps because...' can help.

Section D: Fill in the Blanks

User: Mia
Need: to read the screen easily
Feature: a zoom button

User: Mia
Need: to read the screen easily
Feature: a zoom button

User: Mia
Need: to read the screen easily
Feature: a zoom button

Zoom helps Mia because text gets bigger.

Need: to read the screen easily
Feature: a zoom button
Reason: the text gets bigger

Section E: Spot the Error

D — The reason must explain how the feature meets the need. Being cheap has nothing to do with reading text. It should say something like 'It helps because text is big'.

A — The user must be a person, not a thing. A school bell is not a user. It should name Ava, who is deaf.

C — A spell check tool does not meet Tom's need to hear words aloud. The feature should be a read-aloud button.

B — A GPS arrow is a feature, not a need. The need is what Lena wants to do: find the way home.

B — The user is the person who uses the system, not the system itself. It should say 'The user is Zoe.'
