Why wait months to test an idea, when it can be done in days? Shorten the innovation process and break through endless debates. The one-week Service Design sprint, based on the Google Design Sprint methodology, is the fastest method to test a certain product or feature and know if further investments are wise. In a service design sprint we bring together experts of your organisation and Koos to go through five battle-tested steps. Koos facilitates service design sprints that are tailored to the requirements of your team and challenge. The validated results of a service design sprint can be tweaked and refined in a UX Design Sprint.
