Study Notes
Design Challenges
- Interaction designers face a daunting problem due to the lack of constraints in digital interfaces and objects, unlike industrial designers working in the real world.
Organizational Structure and Strategy
- A good design starts with an agile organizational structure and a comprehensive business strategy that incorporates diverse design processes.
- Companies like Apple, Pepsi, Philips, and Kia Motors have hired Chief Design Officers (CDOs) to recognize the unpredictability of design.
Design Process
- A robust and flexible design process is required due to the dynamic nature of design.
- The design process consists of a four-phase iterative cycle:
- Requirements analysis (Phase 1)
- Preliminary and detailed design (Phase 2)
- Build and implementation (Phase 3)
- Evaluation (Phase 4)
- The cycle is repeated until the outcome from the evaluation phase is acceptable.
Organizational Change
- Resistance to new techniques and changing roles for software engineers can be a problem in traditional organizations.
- Creative leaders blend inspiration and provocation to appeal to the desire for quality that most professionals share.
Business Case for Usability
- The business case for focusing on usability has been made powerfully and repeatedly.
- Benefits of usability engineering and interaction design include:
- Shortened learning times
- Faster performance
- Lower error rates
- Higher rates of conversion
- Enlarged market share
- Increased customer retention
- Fewer returns/complaints
- Increased brand loyalty
- More referrals
Design Methods
- Design methods are the practical building blocks of the design process.
- Common design methods include:
- Sketching
- Paper mockups
- High-fidelity prototypes
- Guidelines documents
- Patterns and best practices
- Dedicated wireframing tools
Prototyping
- Prototypes are powerful design tools that allow users and designers to see and hold representations of the intended interface.
- Prototypes can be physical or interactive, and varying levels of realism can be achieved depending on the time investment in creating them.
This quiz explores the principles of good design, the challenges of interaction design, and the importance of organizational structure in achieving design goals.
