The sooner we can find which features
are worth investing in, the sooner we
can focus our limited resources on the
best solution to our business problems.

Quantitative Qualitative
What? Why?
Data is solid and repeatable
Confirm and deduce
Result-oriented
Large sample sizes
Data is rich and deep
Explore and describe
Process-oriented
Small sample sizes
A/B or multi-variant testing
Analytics
Remote un-moderated
usability testing
Surveys
Focus groups
Cognitive walkthroughs
Moderated usability

1. Background
2. Falsifiable Hypotheses
3. Details
6. Next Actions
5. Validated Learning
4. Results
User 1 User 2 User 3 etc.
Hypothesis 1
Hypothesis 2
Etc.
What feature or assumption to test
What questions to ask
How well does X perform
Etc. What to test next
What hypothesis do we want to validate
1. That majority of users think X
2. That majority of users perform Y
3. That majority of users need Z
4. Etc.
Previous experiment taught us
We want to find out
We want to test our solutions
1. We can proceed with X
2. We need to tweak Y
3. We need to pivot and get rid of Z
Title: Experiment 2: XXX Author: Created:
From focus groups, it was clear that one barrier
with other online providers has been the lack of
trainer support
That providing access to trainers in the classroom
and telling students upfront about trainer
availability will eliminate barriers and increase
conversion
Show users the marketing pages that talk about
trainer availability
Show users the classroom with the trainer being
online
Users indeed look for trainer availability and are
comforted by knowing OTI provides access to
them
Test something else! ; )

Thank you
Qualitative data can in fact be
converted into quantitative
measures even if it doesn't come
from an experiment or from a large
sample size.
Jeff Sauro Measuring Usability
#3: 15 years in the usability and UX space, most of it at the management level of some sort
Last stint before Dius was 8 years at Stamford (Auss largest specialised UX agency)
Ive done my 10000+ hours
#6: privately owned
100 staff in both Melb & Syd
In May next year we will be 10 years old
SW engineers at heart, BA, hardware engineers, UX
Agile and nimble
People drive our culture to innovate
We believe in a strong and vibrant community.
We sponsor conferences and meetups.
Our employees give their time and skills to solve community problems.
#7: Product and technology strategy: what product should be built, how to get it to market. We do this for our own products too.
Web applications: QANTAS-Jetstar accommodation booking, Vodafone self-service
Application-specific devices: a fridge magnet for displaying in-home energy usage
Mobile applications: the iPad app for Australia Post Digital Mailbox
#9: Any uxers out there? Hand up. Who can confidently define what UX means?
#10: Firstly, most people still dont know the breadth of user experience skillset (uxisnotui)
#17: UX metrics are relatively easy and black and white, so I wont be covering them today. You can google and find out all about them.
#18: In this Im going to cover the qualitative aspects.
#19: So youre probably thinking to yourself what does Qualitative measurements look like in your agile project
#21: When you dont have access to users. I used this when working for an enterprise startup - OTI
#22: Enterprise startup using Lean Startup approach.
#25: Next best thing to users
Managed to capture and count the number of times the following themes occurred:
Motivations and expectations to study
Concerns/fears/barriers/pain points
Ideal experience and channel
Outcome:
Personas
Feature sets
Hypotheses
#26: Watch out for anecdotes. Plural of anecdote is anecdotes, not data!
#31: Qualitative, small size but to go deep and understand sentiments, reasons for behaviours and perceptions etc.
As we had planned to run experiments throughout the project, keeping it lean and light was important.
#32: Things to look out for when running group-based sessions: poor facilitation, group think,
In quant, each data is seen as being independent. In a focus group, the entire session = 1 data point, due to Group Think effect.
We split users up and do activities to increase our data points
#50: So how much do these activities cost
Ux REDUCES COST
INCREASES PRODUCTIVITY
SALES
BRAND LOYALTY AND ADVOCAY
Just to name a few
Research was done by Forrester Research that suggested the cost of fixing code was 10 times the cost of the design activities if done upfront , and up to 100 x when the product was launched
#51: We have trusted partners / market research recruiters that find our users form a large database
#53: Picking the right technique is very important. And these questions can help you choose and narrow down on the technique you need.
#54: For the OTI project, I spent 1 hour very early on defined the research/experiment approach, costed it and put it to the PM. It was included in the budget and signed off.
Now some of you may not have access to the person with the wallet, or the budget may have already been allocated prior. In this case, you may have to take a more guerrilla approach to your experiments, OR find an advocate who can play in your team to try and convince a minimum number of user sessions.
#55: Keep it lean, quick and fast
5 6 users per experiment
Prioritise issues
Feedback quickly
You dont want to be seen as been the bottleneck pragmatism is important
#56: Get them to observe
If not, make sure you run through your issues
Agree on pivots and recommendations
#57: Use consistent approaches to test and report
Consider using templates
Benchmark as design matures for future measurability
#58: Use consistent approaches to test and report
Consider using templates
Benchmark as design matures for future measurability
#62: If too expensive, to Guerrilla Usability Testing
Shorter, often 15 30 mins
Few features tested
Often, on the road or at the participants location, and with some training developers can do it (Steve Krugs book This is not Rocket Surgery)
Book by Steve Krug Rocket Surgery Made Easy provides tips on how anybody can conduct usability testing.
#63: You can convert a usability problem into a frequency, using confidence intervals
Categorizing and counting issues
N= + 30 = good estimate for standard deviations, otherwise stick with t-distribution
#64: As the product matures, you can introduce more UX metrics and quantitative measurements
#65: Measuring the User Experience is more statistical, and assumes you have an existing product or service.
