Expert Evaluation via the Audit

I Walkthroughs; and

Think!

Kinds of questions you are asking, expertise of the ‘expert’.

Fieldwork

I In-Situ / In the Wild;

I Anthropological - small sets of people.

Difference is in the intention - Not to inform design - but to

evaluate the correctness!


...expanded in ‘Qualitative (Fieldwork) Methods’ (pg. 235)


Unobtrusive

Problems with ’normal’ Observation.

Guinea Pig: people feel like guinea pigs, therefore

change their behaviour patterns;

Role Selection: participants see the experimenter as

having an elevated status, therefore

following that experimenters lead;

Measurement as Change: aspects of experiment introduces real

changes, and

Response Sets: respondents will more frequently

endorse a statement than disagree with

its opposite.

Design criteria to avoid these.


...expanded in ‘Unobtrusive Methods’ (pg. 236)


Longitudinal Observation

Observation of user behaviour when interacting with applications

and the Web – especially for the skill gaining process – is better

observed at a longitudinal fashion. This statement is founded on

the fact that increased intervals enable the consolidation of

declarative knowledge in long-term memory, where consolidation

does not happen automatically and it is not determined at the

time it has been learned. In order to gain insights into the user

experience in the context of your development, we should conduct

a longitudinal analysis of those users if at at all possible.

Questions Regarding this Lecture!

The User Experience from 30,000ft Break! 10 / 22


Quantitative

Time etc

Laboratory, experimental - not well used in company based UX.

Card Sorting

Sorting representations into an order based on some criteria.

Triadic elicitation

Understand differences which are not immediately obvious.

Analytics

PULSE Page views, Uptime, Latency, Seven-day

active users, and Earnings and

HEART Happiness, Engagement, Adoption,

Retention, and Task success.

Analytics

Experience monitoring a qualitative representation of a single

session

Mindshare goals qualitative measures such as awareness,

branding effectiveness.

Customer support responsiveness and Customer satisfaction

evaluation.

Think-Aloud

Classic of the UX evaluation process evolving mainly from design

based approaches. It produces qualitative data and often occurs

as part of an observational process, as opposed to a direct

measurement of participant performance, as would be normal in

laboratory settings.


...expanded in ‘Think-Aloud’ (pg. 242)


Co-Operative Evaluation & Participatory Design

Enabling each individual to fully interact within the discussion

process while the UX specialist remains outside of the discussion

just acting as a facilitator for the participants views and thoughts

is a key factor in the process design.

Think Pair-Programming with Users!

The Great Measurement Debacle of 2012

Nominal Scale: Which denotes identity;

Ordinal Scale: Which denotes identity and magnitude;

Interval Scale: Denotes identity, magnitude and has the benefit of

equal intervals; and

Ratio Scale: Which has the positive properties of the three we

have already seen as well as a true zero point.


...expanded in ‘Measuring Variables’ (pg. 210)


Hybrid Methods

...known also as mixed methods or triangulation

Are terms used to denote the use of many complimentary

methods because the UX specialist recognises the inadequacies of

a single method standing alone. Indeed, the hallmark of being a

field practitioner is flexibility in relation to theoretical and

substantive problems on hand.
