A methodology to explore solutions to problems of public organizations like cities. The largest project produced the playbook how cities can mix the new private (e.g. bikesharing, UBER/Lyft, car-pooling etc) with traditional transit options. The result was used by cities representing over 20 million people. We defined personas and use cases, developed solutions together with private-sector companies, examined the impact by using acutal data and confirmed the desirability of the solutions by engaging and surveying the local community in the lead city. As a result we were able to document recommendations for the future of mobility and integration of the different systems.
