Step 2: C2="Positive"

Step 3: AND(TRUE, TRUE)

Step 4: IF(TRUE, "Yes", "No")

Cell Reference Map

    A           B           C           D
1 | Design Idea | Prototype  | Feedback   | Validated
2 | Login      | Yes ------> TRUE       | Yes
3 | Checkout   | No  ------> FALSE      | No
4 | Profile    | Yes ------> TRUE       | No
5 | Search    | Yes ------> TRUE       | Yes

Cells B2 and C2 are checked to decide if design is validated in D2.

Result

    A           B           C           D
1 | Design Idea | Prototype  | Feedback   | Validated
2 | Login      | Yes        | Positive   | Yes
3 | Checkout   | No         | N/A        | No
4 | Profile    | Yes        | Negative   | No
5 | Search     | Yes        | Positive   | Yes

The Validated column shows 'Yes' only when prototype exists and feedback is positive, confirming prototyping validates design ideas.

Sheet Trace Quiz - 3 Questions

What does the formula check first?

A If design is validated

B If user feedback is positive

C If a prototype was created

D If feedback is negative

Key Result

IF(AND(prototype_created = 'Yes', user_feedback = 'Positive'), 'Yes', 'No')

Practice

1. Why is prototyping important in validating design ideas?

easy

A. It is only useful after the product is fully built.

B. It replaces the need for user feedback entirely.

C. It guarantees the final product will have no bugs.

D. It helps test ideas quickly and cheaply before final development.

Solution

1. Step 1: Understand the purpose of prototyping

   Prototyping allows designers to try out ideas early without full development costs.

2. Step 2: Compare options with prototyping benefits

   Only It helps test ideas quickly and cheaply before final development. correctly states prototyping helps test ideas quickly and cheaply before final development.

3. Final Answer:

   It helps test ideas quickly and cheaply before final development. -> Option D

4. Quick Check:

   Prototyping = Quick, cheap testing [OK]

Hint: Remember: prototyping saves time and money early [OK]

Common Mistakes:

• Thinking prototyping removes need for user feedback
• Assuming prototyping guarantees bug-free final product
• Believing prototyping is done after full product build

2. Which of the following is the correct way to describe a prototype in Figma?

easy

A. A static image with no interaction.

B. A fully coded application ready for deployment.

C. An interactive design that simulates user flow.

D. A text document describing the design.

Solution

1. Step 1: Define what a prototype is in Figma

   A prototype in Figma is an interactive design that simulates how users navigate the interface.

2. Step 2: Evaluate each option

   An interactive design that simulates user flow. correctly describes a prototype as interactive and simulating user flow; others are incorrect.

3. Final Answer:

   An interactive design that simulates user flow. -> Option C

4. Quick Check:

   Prototype = Interactive design [OK]

Hint: Prototypes simulate interaction, not just images [OK]

Common Mistakes:

• Confusing prototypes with static images
• Thinking prototypes are fully coded apps
• Mixing prototypes with documentation

3. What is the main benefit of using interactive prototypes when presenting to stakeholders?

medium

A. They improve communication by showing how the product works.

B. They guarantee the product will be built faster.

C. They replace the need for user testing.

D. They reduce the need for any further design changes.

Solution

1. Step 1: Identify the role of interactive prototypes with stakeholders

   Interactive prototypes help stakeholders understand the product by showing its flow and behavior.

2. Step 2: Analyze each option

   They improve communication by showing how the product works. correctly states that prototypes improve communication by demonstrating product functionality.

3. Final Answer:

   They improve communication by showing how the product works. -> Option A

4. Quick Check:

   Interactive prototypes = Better communication [OK]

Hint: Show, don't just tell, to communicate design [OK]

Common Mistakes:

• Assuming prototypes remove all design changes
• Thinking prototypes replace user testing
• Believing prototypes speed up build time automatically

4. You created a prototype in Figma but users report they cannot click buttons to navigate. What is the likely issue?

medium

A. The prototype file is corrupted and unusable.

B. You forgot to add interaction links between frames.

C. Users do not have permission to view the file.

D. The prototype is too complex to run on browsers.

Solution

1. Step 1: Identify why buttons are not clickable in Figma prototype

   Buttons need interaction links connecting frames to enable navigation.

2. Step 2: Evaluate other options

   You forgot to add interaction links between frames. correctly identifies missing interaction links as the cause; others are less likely or unrelated.

3. Final Answer:

   You forgot to add interaction links between frames. -> Option B

4. Quick Check:

   Missing links = No button clicks [OK]

Hint: Check if interaction links exist for clickable elements [OK]

Common Mistakes:

• Assuming file corruption causes click issues
• Blaming user permissions for navigation problems
• Thinking complexity breaks browser prototype

5. A team wants to validate a new app design quickly. They create a prototype but skip user testing. What risk does this pose?

hard

A. They might miss usability problems that only real users find.

B. The prototype will automatically fix design flaws.

C. Skipping user testing saves time without any downside.

D. The final product will be perfect without testing.

Solution

1. Step 1: Understand the role of user testing in prototyping

   User testing reveals real usability issues that designers may overlook.

2. Step 2: Analyze consequences of skipping user testing

   They might miss usability problems that only real users find. correctly states the risk of missing usability problems without user feedback.

3. Final Answer:

   They might miss usability problems that only real users find. -> Option A

4. Quick Check:

   User testing finds real problems [OK]

Hint: Never skip user testing to catch real issues [OK]

Common Mistakes:

• Believing prototypes fix all flaws automatically
• Thinking skipping testing has no risks
• Assuming final product is perfect without testing
