Refined Waterfall Model ?

Software + Human-Computer Interaction:

Waterfall model
> Spiral Model
> > JAD/RAD

> Star Model
> > Usability engineering

3

The Star Model ?

Evaluation:
> Implementation
> Prototyping
> Conceptual Design
> Requirements/specs
> Task/Functional Analysis

4

What are the 4 core evaluation paradigms ?

1. Quick & dirty
Focus on these:
2. Usability testing
3. Field studies
4. Predictive evaluation

5

Techniques for usability testing ?

1. User testing
2. Observing user activity
3. Questionnaires/interviews

6

Field studies ?

- 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

What are the two methods of predictive evaluation ?

1. Inspections - experts predict problems
> I. Heuristic Evaluation
>> II. Walk-through

2. Predictive Models - provide measures of user performance

8

What does the 'Inspection' part of the predictive evaluation consist of ?

- Heuristic evaluation pioneered by Nielsen
