THE USABILITY SPRINT

VALIDATED INTERFACE

ELEMENTS VS. USERSTORIES

REFINED USER

STORIES & MOCKUP’S

So you don’t deliver asolution no one can

use.

So you practice drivingto user stories and

test yourself on yourunderstanding andreadiness.

DONALD NORMAN’S 7 STEPS

Signifier: The dial suggest anup/down affordance

JUST ANOTHER

YUCKY TUB?

Affordance: The tub dial in fact

offers an up & down movement

Constraint: The dial only goes up anddown (not side to side, etc.)

Feedback: When water is running,you can tell whether the drain isstopping the water.

Mapping: The dial controls theopening of the drain- a wellunderstood conceptual model.

STEP 1: ID WHAT YOU NEED & FIND COMP’S

Don’t reinvent the wheel.(startup’s have enough risk)

Identify the interface elements you

need, then find comparables andexisting patterns.

YOUR BRIEF

Who & What?We want to make an assessment of the user’s relationship to

 the available affordances and their appropriateness to [x set of

user stories].

Why?We need to determine if our current approach is likely to be

usable to [personas] so we decide on possible revisions.

How?Our deliverables will be: a research design with subject testresults as well as possibly notes and revisions to our current

user stories and test cases.
