Module 10

Question 1

What is a prototype?

Answer 1

1. Simulates a product : in order to understand how that product works
2. Simulates the interactive experience
3. Allows the design to be tested with users
4. Communicates the solution to stakeholders
5. Prototypes are a work in progress
6. The purpose of a prototype is to improve the design

Question 2

Why prototype?

Answer 2

1. Helps improve the quality of designs
2. Identifies issues before the build
3. Reduces the risk of building flawed products
4. Reduces cost in the medium time
5. Helps validate (or invalidate) assumptions
6. Helps share ideas with team mates and stakeholders

Question 3

Prototyping helps manage stakeholders

Answer 3

1. Communicate design ideas clearly
2. Reduce ambiguity (creates a clear vision)
3. Get executive feedback and buy-in
4. Improve decision-making
5. Showcase design flair

Question 4

Choosing the right prototype

Answer 4

Choosing the level of fidelity depends on:

1. Available resources and skills
2. Time available
3. The audience you are presenting to ( the further the audience is from the design process the higher the fidelity needs to be)
4. What needs to be tested

Question 5

Low Fidelity

Answer 5

What can you learn from low fidelity prototypes:

1. If broad concepts and mental models make sense to users
2. Finding out if users “get it”
3. Optimising flow (making sure sequence of screens is efficient and makes sense to users)

Question 6

Benefits of low fidelity prototypes

Answer 6

1. Quick and easy to produce
2. Catches potential problems early
3. Low skill level required to product

Question 7

Cons of low fidelity prototypes

Answer 7

1. Limited learning (can only test high level flow and mental models)
2. Can’t test interactions, screen states or product experience
   3.

Question 8

Medium fidelity prototypes

Answer 8

What you can learn from a medium fidelity prototype:

1. Learn more detailed concepts and flows (ensure user’s mental models are aligned and concepts are grasped)
2. Learn about screen layout and hierarchy
3. Basic interactions
4. Navigation
5. Copy and labelling

Question 9

Medium fidelity prototype benefits

Answer 9

1. Relatively fast and inexpensive to produce
2. Easier to test with users
3. Easier to communicate with stakeholders
4. Richer data and insights

Question 10

High-fidelity prototypes

Answer 10

What you can learn from a high fidelity prototype:

1. Assess flows and concepts
2. Assess screen design and layout
3. Assess performance of form designs
4. Test rich interactions such as mapping

Question 11

Benefits of high fidelity prototyping

Answer 11

1. Richer user testing
2. Developer understanding
3. Stakeholder buy-in

Question 12

Wireframes

Answer 12

The schematic representation of the layout and functionality of a screen

Question 13

What makes an effective wireframe

Answer 13

1. Limited to key page elements
2. Quickly conveys the hierarchy of elements
3. Avoids stylistic details
