CHARITY WATER’S WORK IN THE PAST EIGHT YEARS

Testing keeps you honest

Testing keeps you moving forward

Testing produces data

Data gives you power

“..half of product features are not only wasted, but actually have a negative impact on user experience and ultimately business goals.”

-Indeed Study, 2013

TEAMWORK

» Identify what to test, why and how success will be determined. Ideas for testing are often based on user research or data mining

» Watch test, report on results, identify, statistically sound response rate, pivot if necessary

» With test criteria in mind, design small, measurable test variants

» Ensure test is as unbiased as possible, one key element should differ between test variants

» Instrument via analytics such that test metric(s) can be tracked

» Implement test and watch for biases
