It is based on the following philosophy:
Design is an art of creating beautiful, elegant, and innovative solutions, which works in the user and customer context.
Design is an accident that kicks in at conception, and D3 creates maximum opportunities to make accidents happen.

DDD vs TDDSomething... driven development
You write first the tests in order to have the tests as a point of reference for your logic
The tests protects your application, the tests runs before the deployment and assures that nothing is broken (by mistake) on your code
The tests helps you understand the needed functionality better and write better code
You design first the way your “ideal” experience your user (potential customer) wants
You create designs (personas/entities, work-flows, task-flows, wireframes) and you make sure “everyone” and “everything” have them as a point of reference
You execute according to the designs, in order to focus and deliver what the designs aspired to deliver!
