What this video covers
The double diamond model shows design as two diamonds: the first explores then defines the right problem, the second explores then delivers the right solution. Each diamond opens wide before narrowing to a point.
Stepping through the four phases, you felt the rhythm the shape is really about: open up, then narrow down - twice. The widening half is permission to explore before you commit; the narrowing half is the discipline to choose. Skip either diamond and you solve the wrong problem, or solve the right one carelessly.
