Hoe kun je user research inrichten zodat het past binnen het snelle, iteratieve agile proces? Hoe kun je laten zien wat de business value van user research binnen agile is? Wij hebben een manier gevonden om de gebruiker een vaste rol te geven in het agile proces. Inmiddels is gebruiksonderzoek bij IceMobile volledig geïntegreerd in onze agile manier van werken en doen we bij verschillende projecten in elke sprint gebruiksonderzoek. Ik deel in deze presentatie wat voor ons de grootste uitdagingen waren en wat onze manieren zijn om het te laten werken.
17. Transfer information effective
The team should learn most of the user test, not the UX researcher
Fit the user into the process
Do testing so that it is not ‘extra work’
Make results visible
Value should be clear and measurable
We wanted to find a way to:
19. Which practice proved its value?
Individuals and interactions
Working software
Customer collaboration
Responding to change

Usability Testing is an iterative process!

33. Pulse: iterative User Involvement
•Prioritize: test important part(s) most extensive
•Frequent: reliable results, also test improvements
•Empathize: learn what matters to users
•Optimize: learn to test
Allow responding to change

I've just found 10000

34. Pulse UX TestingTraditional UX testing
Iterative UX testing:
every 2 weeks
UX testing (near)
the end of a project
Continuous testingSingle test
Small sessionsBig session
Performed by the teams:
the team members learn most
Performed by researchers:
the researchers learn most
Changes early in the process;
thus less costly
Changes late in the process;
thus very costly
Rise in ‘first time right’
of features
Few ‘first time right’
of features
120% end-result
in 80% of the time
Difficult to measure success
35. Transfer information effectively
