Here we are: all ideas from previous days will be consolidated on day 4's prototype. One day to make what is sometimes a blurry concept look tangible and testable.

At Design Sprints Switzerland , the Sprintmasters, who are also Designers, will handle the creation of the prototype. The rest of the team can relax and go about their business. However, it is desirable that a member of the team (ideally the project manager) remains available in order to validate the progress of the prototype. On this day it is perfectly possible to work remotely, we communicate through chat, Skype or phone.
