Systems
R&D project complexity in systems
• Time-Budget-Scope
• Technology
• Multi-design teams
• Various disciplines
• Integration
• Costly cycles
Some interaction differences
System
• System operator
• Error and malfunction handling
• Different levels of maintenance
• Various interaction points
• Various interaction means
• Asynchronous behavior
Product
• User
• Error and malfunction handling
• Simple maintenance
• Defined HMI
• Eexpected functionality
“Our system is very complex, it will take the users
a lot of training and practice to learn how to use it”
Overcome misconceptions
7
• Complexity of a system
≠
complex interface
• R&D investment Vs long term costs
• Team commitment to usability
Challenges
Interaction design in
complex systems is an
organizational challenge
3 Foundations of Implementation
Engagement
Methodology
Awareness
3 Foundations of Implementation
Case studies, ROI, management support, experienceAwareness
Main benefits
R&D
Solving HFE & ergonomic challenges
Shortening R&D duration
Saving design cycles
Lowering production costs
Product
Simplified operation
Error prevention
Safe working environment
Short training time
Service costs reduction
Satisfied customers
3 Foundations of Implementation
Customer study, requirements management,
task analysis, operational concept
Methodology
Awareness Case studies, ROI, management support, experience
END TO END
VISION
Requirements management
an integrative process
System definition – expected performance Task analysis – user’s job
System requirements High level requirements Operational concept
System modeling
System architecture design Detailed design User Interface Definition
Subsystem requirements cross system engagement Implementation
System Integration design dilemma solving UX Intervention
System Validation Usability testing
– system performance – user’s performance.
System Engineer Human Factors Engineer
Step II
Functional requirements
Suggested operational concept and
user interface, maintainability approach
Align with system engineering
What are the anticipated user actions?
Operational analysis, Ideation
Step III
Detailed requirements
GUI and physical interfaces Align with sub-system designers
Task analysis, ergonomic analysis
Step IV
Process control
Implementation validation, dilemma
solving
Cross-discipline alignment
Locate conflicts, attend design reviews
Step I
High level system requirements
What are the human factors principles
of the system?
Align with marketing
User research, similar products, older
models feedback

Usability forum
Design checkpoints
• Subsystems requirements
• Task Analysis
• Design reviews
• Usability testing
Teamwork effects
• Simplification of operation
• Clear and consequential operational approach
• Clear and consequential malfunction handling approach
• Subsystems operation
• Coherent interface language
How it’s Done?
Set the a team
Define your goals
Identify weaknesses
Deploy methodology
Get involved
Test
The art of alignment – Different point of view / Same goal
Enterprise Vs. Start-Up – Find what works for you
Designated team – HFE is not a “by-product”
“ If the user can’t use it, it doesn’t work”
