Quick Questions

Shade in the A or B circle for each question.

1. What is the main focus of user-centred design?

A Building the solution around the needs of its real users

B Building the solution around what the developer finds easiest

2. When should users be involved in user-centred design?

A Throughout development, from early planning to final testing

B Only after the solution is finished and released

3. Which action is an example of identifying user needs?

A Choosing the colour scheme the developer likes best

B Surveying and interviewing the people who will use the app

4. A tester says the menu buttons are too small to tap. What should the developer do under user-centred design?

A Ignore the feedback because the code already works

B Revise the design, such as making the buttons larger, then check again with users

5. True or false: user-centred design only needs feedback collected once at the start of a project.

A False: feedback is collected repeatedly and used to refine the design

B True: one round of feedback is enough for the whole project

D print(count, "comments")

Question 2

A needs = ["fast", "simple"]

B for need in needs:

B for user in users:

C print("Survey", user)

Question 4

B total = sum(ratings)

C average = total / len(ratings)

D if average > 3:

E print("Revise design")

Answer Key

User-centred design

Section A: Quick Questions

A — Building the solution around the needs of its real users

A — Throughout development, from early planning to final testing

B — Surveying and interviewing the people who will use the app

B — Revise the design, such as making the buttons larger, then check again with users

A — False: feedback is collected repeatedly and used to refine the design

Section B: Match the Pairs

user-centred design → Designing a solution around the needs of its real users and involving them throughout development

survey = ask_users("What do you need?") → Identifying user needs by asking real users what they require from the solution

Involving users in feedback: collect their comments on a prototype so the design can be improved → feedback = get_feedback(prototype, testers)

Revising the design from user feedback: change the design when users report a problem → design = revise(design, feedback)

design = build(developer_ideas) release(design) → The design is built only from the developer's own ideas. User needs were never identified, so it is not user-centred.

needs = ask_users() design = build(needs) release(design) → Users are asked once at the start but never involved again. There is no feedback step and no revision.

Section C: Definitions

user-centred design — Designing a solution around the needs of its real users, by finding out what they need and involving them throughout development, using their feedback to revise the design.

Section D: Fill in the Blanks

feedback = []
feedback.append("menu is confusing")

for comment in feedback:
    print(comment)

version = 1
if "confusing" in comment:
    version = version + 1

need = input("What do you need? ")

rating = int(input("Rate 1-5: "))
if rating < 3:
    print("Revise the design")

Section E: Spot the Error

C — Lists have no .len() method. Use len(feedback) to count how many pieces of user feedback were collected.

C — The loop should print each single need, so it must use the loop variable need. Printing needs shows the whole list every time.

A — The list items must be separated by a comma. It should be users = ["Sam", "Priya"] so the real users to survey are stored correctly.

D — The design should be revised when users rate it LOW. The condition should be average < 3, so poor feedback triggers a revision.

A — print() only displays text and returns None. To collect feedback from the user, use input("Any issues? ").
