DESCRIPTION
At agile testing days 2012 Gojko Adzic gave us a mission: “Test the next level in the software quality hierarchy!” This year I’d like present how testers can test usability, usefulness and in the end the successfulness of the software. This is a type of testing the business actually wants to pay for because it provides focus in gaining value. Knowing your customer is the most important focus a tester needs to achieve this goal. In this presentation I elaborate techniques and tools that provide you information on your customer’s journey. In order to know if your software is useful you need to analyze the journey your customer takes using the services your company provides. This goes beyond just one product. It concerns your complete customer experience. This analyses provides input for your impact maps. They can make your impact maps less assumption based. Furthermore I show that with the help of A/B Testing you are able to shorten the feedback and so ruling out branches of your impact map. With this focus and the use of these techniques testers are able to bring testing to the next level. Testing is not only about technology any more. Testing on actual business value is at reach and we testers can bring that change!

User-centered design
User-centered design =
a problem solving process that requires:
• Designers to analyze and foresee how users are likely to use a product.
• Test the validity of their assumptions with regard to user behavior in real world tests
with actual users.
