Q
What’s the traditional waterfall model ?
A
Requirement analysis > Design > > Code > > > Test > > > > Maintenance
Flaw: requirements change over time
2
Q
Refined Waterfall Model ?
A
Software + Human-Computer Interaction:
Waterfall model
> Spiral Model
> > JAD/RAD
> Star Model
> Usability engineering
3
Q
The Star Model ?
A
Evaluation: > Implementation > Prototyping > Conceptual Design > Requirements/specs > Task/Functional Analysis
4
Q
What are the 4 core evaluation paradigms ?
A
1. Quick & dirty Focus on these: 2. Usability testing 3. Field studies 4. Predictive evaluation
5
Q
Techniques for usability testing ?
A
- User testing
- Observing user activity
- Questionnaires/interviews
6
Q
Field studies ?
A
- Carried out in natural setting
- Goals: increase understanding about what users do naturally, and how tech impacts them
- Used to identify opportunities, design requirements, how to best introduce tech
- Can take from minutes to years
7
Q
What are the two methods of predictive evaluation ?
A
- Inspections - experts predict problems
> I. Heuristic Evaluation
» II. Walk-through - Predictive Models - provide measures of user performance
8
Q
What does the ‘Inspection’ part of the predictive evaluation consist of ?
A
- Heuristic evaluation pioneered by Nielsen
