The product is the rectangle, each corner representing goals, the bigger goals a product has; the more extreme the angle and stretched out a corner of the shape is.
Your goal is to roll along in your car, with bumpy wheels, shaping the product to roll better while maintaining the core structure.
Execution shapes the wheel.
Bumping along, shaping and rounding the product as you go along, shaping can go smoothly if done right, if a wheel turns too quickly or hits a bump in the wrong place, it might make the product less smooth or damage the structure.
The path along the way can be challenging, being cautious and slowing down in uncharted terrain while maintaining a steady pace will keep your wheels in great condition, and once your wheels are nice and round, you can pick up speed.
