The betterplace lab follows an application- and output-oriented approach that is further fine-tuned by feedback loops. We identify relevant themes and develop concepts through previously available studies as well as with our own independent research. Whenever possible, we then conduct pilot studies with chosen users (from the betterplace.org community) to empircally and quickly test our applications in order to discover the best possible methods. This form of "rapid prototyping" allows us to make any necessary adjustments to our results and tools so that we can offer them to a larger user group. The cycle is closed with a project evaluation phase, from which further pilot tests are run and the process is repeated. This methodological approach is reflected in our individual projects as well.
