Speaker notes:
As who loves fitness?
Get some hands in the air.
Reveal that they were actually volunteering to do planks on stage - bring them up for the duration of the talk.
Talk about how in testing, you have to frame your questions in a way to not bias the answer
Fake it til you make it
A bit about my journey.
DTP freelance/webagency student
Computer Science —> Information Science (UX Design)
Accenture, Google: design on the side
Startups: delta method brandwatch
Accenture: product design, design system
How UX relates to business analyst?
This will probs feel rushed. Ask questions throughout.
Intro
What is prototyping?
Where does it fit?
How do you convert requirements into prototypes
Types:
which
what they’re good/ bad for
when to use which
Design Thinking according to Stanford School, is a linear process
building a product, is a circular process
This design flow exists on many levels, scales and variants
GOAL:
Validate assumptions
Generate confidence in direction
Design process is about making -> Doing is the best kind of thinking —> show don’t tell
Find the quickest path to the experience
Use methods and materials that move at the speed of though to maximise learning
At what stage are you at? and how can we make the learning loop smaller?
Test the right thing, know your riskiest assumption, ask the right question
Test it in the right way, figure out how to measure it,
Build it in the right way: Get there fast, Cheap, easy, Choose the right tool for the job
So what are the tools
How do you bring ideas to life?
Ranges in fidelity, complexity and testability
Range from wireframes -> lofi mocks -> hifi mocks -> click through dummies
Range micro interactions -> flows -> parts of apps -> A/B testing
A/B Prototypes
Design Thinking -> linear
Product -> circular
GOAL:
Validate assumptions and
Generate confidence in direction
Ask the right question
Doing is the best kind of thinking —> show don’t tell
