1. SysML V2: User-Centered Design Approach
Tricia ngoon

2. Objectives Define minimal usability requirements for SysML version 2
Develop a process for identifying real user needs

3. User Classes New modelers Seasoned modelers Consumers of model data
Early career and experienced systems engineers learning SysML
Seasoned modelers
System engineers with experience in modeling, comfortable with using SysML and modeling tools
Consumers of model data
Other engineering disciplines who do not use SysML modeling tools, but need to understand and interpret model information

4. User-Centered Design
A methodology of design that involves the user at every stage in the process
Involves designing for each group of users
Involves rapid prototyping, testing, and iteration

5. Storyboarding

6. Storyboarding Process
Storyboards depict scenarios that would realistically happen to a user
They present a user need and a potential solution.

7. Prototyping

8. Paper Prototypes
Rapid low-fidelity prototypes meant to mimic what a full user experience might look and feel like
A way to come up with quick brainstorms and ideas to test without added cost and time of development
