There is something magical about a tight schedule combined with immediate prototyping and user feedback.
We use code for prototypes. This enables a seamless transition to the minimum viable product, the MVP.
Innovation is no longer a black box run by experts. Prototypes need to be created immediately. You need to be able to test them on real devices, in real context, with real users.
We use a unique design sprint in the beginning. It involves the core stakeholder and end users in a cost-effective way.
We build prototypes immediately, and test them in an iterative manner to learn what works.
The prototype evolves into the product. There should be a continuous evolution from the first prototypes to the launch.
All the work should go into adding value to the end result. Work that does not directly add value to the end result should be minimized.
