3. How do we make effective use of the information?

Design method Step 1: Get Key Facts about Users
How do we get the user information?
Gain access to users Meet users in the right environment Prepare for the meetings Practice Guided Listening™ Create user reports Create a matrix of key user characteristics
and needs

Design method Step 1: Get Key Facts about Users How do we make effective use of the information we’ve gathered?
The major problems of UI design “Many users — one user interface” Feature-creep and elastic users Who’s to say what users want?
A persona* with scenarios can help solve the problems of UI design
* Based on the usage of the term coined by Alan Cooper

Persona Step A. Analyze your matrix of key user needs &
characteristics
Persona Step B. Create a hypothetical person who has the common and
most important set of needs and characteristics in the matrix
Design method Step 1: Get Key Facts about Users
How do we create a persona?

Assign weights to key users Make a master list of key needs

Design method Step 1: Get Key Facts about Users
Persona Step B. Create a Persona
“Users” are Elastic Both average and
edge-case Often
interchangeable with “programmer”
Personas are Specific Detailed Named Hypothetical

Design method Step 2: Describe the Tasks the Persona Needs to Perform
Create scenarios
Tasks that your persona wants to accomplish
The main tasks that he or she wants to accomplish
Detailed, step-by-step descriptions

Design method Step 2: Describe the Tasks the Persona Needs to Perform
Required Format for User Scenarios
1. Pragmatic: only scenarios that capture the primary tasks of your target users (contrast with use cases).
2. Created from the user’s perspective with user-based vocabulary that is implementation free.
3. Step-by-step format, limited to 10 steps per scenario.
4. Long tasks are chunked into a series of scenarios that are prioritized by importance to target users.
5. Scenarios are validated with users before testing begins.

Design method Step 3: Create a UI that enables tasks in the Scenarios
Design the UI from the Top Down
1. Start by designing the screen that the user sees first
2. Individuate the tasks in the scenarios by mutual exclusivity
3. Design the main navigation for accessing the tasks from any screen
4. Design the screens for performing each task
