What : User Experience (UX) refers to all the good / bad feelings towards your product
Who : the project manager, UI designer, IA expert, the man/woman ready to make him/her “happy”
Why : if the user is not “happy” he/she will not use your product and will look for a better experience
How : improve the user experience but respect the business goals
Where : in the user environment, where he/she uses normally your product
When : UX can be improved anytime during the development process

eCommerce websites
Different flavours. Similar goals.

2. eCommerce websites
• Different design approaches / Hard to differentiate sometimes
• Huge competition : existing on a global market
• Price comes first, but without a good UX, the user won’t get to that point
• UX it’s not optional
• Depends on the business goals
• Common elements: shopping cart, offers, they want to sell you a product
• Differences: design, anticipate user needs, targeted market, personalisation level

3. UX testing
• There is no silver bullet method
• Time / money constraints
• The client doesn’t always sees why to UX “whatever” test
• Options
• Classic UX testing
• Discount (cheap and fast) testing
• No testing = No results = No user feedback … failures looms around the corner

Classic User testing Discount testing No testing
Methods
user interviews, focus groups,
eye tracking, advanced
prototypes, personas,
scenarios, etc.
expert review, heuristic
evaluation, simple user test,
proto-personas, user journey
graph
being optimist
Cost high low none
Users 5-many 1-5 0
Time 7-30 days 30 min 0
UX team 3-10 1-3 0
Results plenty few none

UX means innovation + evolution
www.amazon.com

UX = Evolution = more $$$

4. Cheap and fast ???
1. When we can not do proper UX testing
2. To convince a client investing in UX
3. Limited budget
4. Limited time
5. Restricted access to users
6. Cannot replace full length UX testing
7. Better little than none !!!
8. Focus on the core features / functions

5. Testing methods
1. Create a set of methods (max 3)
2. Establish a scale of experience values (-10 to +10)
3. Create a user scenario - to attain a goal
4. Apply methods and measure the UX
5. Analyse the top pain points
6. Modify the project accordingly and repeat after an interval to measure improvement

Method A - user journey graph
Heuristic markup / Emotional map / Focus on goals

1. Establish a goal : buy a pair of woman shoes
2. Create a scenario (steps to follow)
3. Pick a typical user / UX practitioner
4. Record the emotions and reactions of the user while
using the website
5. Create a graph based on the reactions of the user
[scale -10 to +10 as reactions] on each page/step
6. Analyse the top 3 lowest points
7. Add comments: type of failure, severity, how it affects
the main goal
