YOU’LL KNOW IT BY IT’S ABSENCE
#NERDERYWEBINAR @THE_NERDERY
#NERDERYWEBINAR @THE_NERDERY
YOU NOTICE THE LACK OF USABILITY WHEN... ¼ Things don’t work as you expected ¼ Tasks require repetitive effort ¼ Your effort seems lost or wasted ¼ It’s impossible to tell if you’re done
#NERDERYWEBINAR @THE_NERDERY
SO WHAT IS AND ISN’T USABILITY?
#NERDERYWEBINAR @THE_NERDERY
#NERDERYWEBINAR @THE_NERDERY
WHAT IS USABILITY?
Usability captures the feedback of users
Usability focuses on the user’s ability to comprehend and utilize the product
Usability tests the product, not the user
#NERDERYWEBINAR @THE_NERDERY
PRAGMATIC DEFINITIONS
Restricted to formal lab settings
Judgmental of user ability
A barometer for user aesthetics
A referendum on designer skill
A license not to fix things
Flexible in setting and format
User inclusive and user centered
A method that evaluates design
A tool for improving design
A test of assumptions, approaches and executions
USABILITY IS… USABILITY IS NOT…

JUDGING THE NEED FOR USABILITY TESTING
NOVELTY & COMPLEXITYThe more you have of each, the more you need to test.
#NERDERYWEBINAR @THE_NERDERY
ALWAYS MAKE ROOM FOR SOME TESTING
#NERDERYWEBINAR @THE_NERDERY
WHEN YOU TREAT USABILITY AS...
Assumptions go unnoticed
Unplanned rework raises costs
Timelines break in QA at latest
Launch quality is a gamble
Assumptions are mitigated
Efforts are scaled and budgeted
Timelines remain stable
Output quality increases
AN INTEGRAL PART OF THE PROCESS AN OPTIONAL ADD-ON
#NERDERYWEBINAR @THE_NERDERY
FIVE POINTS WHERE YOU SHOULD TEST
#NERDERYWEBINAR @THE_NERDERY
GOOD TIMES TO TEST
Articulated Prototype
Pre-testing Concept

TEST EARLY, TEST OFTEN.

CHAPTER 4 OF 5
#NERDERYWEBINAR @THE_NERDERY
THE RISKS OF GOING UNTESTED
Tales of horror, woe, and unrecoverable loss
Quantifiable losses: the wounds you can see
Intangible losses: the awkwardness of
public failure

QUANTIFIABLE LOSSES
® Tannoy
#NERDERYWEBINAR @THE_NERDERY
FUN WAYS TO FAIL
FEATURES UNUSABLE
TIMELINE EXTENDED OR MISSED
BUDGET EXCEEDED
And you don’t have to choose just one.
#NERDERYWEBINAR @THE_NERDERY
INTANGIBLE LOSSES
#NERDERYWEBINAR @THE_NERDERY
SO MANY FUN WAYS TO FAIL
The worst negative feedback is often no feedback at all.
Opportunity pool is
constrained
Users view all of your products
negatively
Credibility takes work to rebuild
Business community sees you as a poor risk

Look for things that will benefit from user insight
Plan testing to support the project’s progress
Allow time to use what you learn in testing
#NERDERYWEBINAR @THE_NERDERY
TEST EARLY, TEST OFTEN
#NERDERYWEBINAR @THE_NERDERY
TEST ITERATIVELY FOR BEST RESULTS
Make a thing to test
Adjust and repeat
(as needed)
Test it
#NERDERYWEBINAR @THE_NERDERY
TEST TO SOLVE PROBLEMS AND ANSWER QUESTIONS
#NERDERYWEBINAR @THE_NERDERY
Test the assumptions, test the concept, test the design, test the code. You should always question everything.
