Sorry, but you completely missed the mark on this one. Are you in UX or have you led design thinking sessions? It's successful because the product stops being something the designer created and starts being a product the whole team created. It gives everyone, no matter your role, a voice in the product and the creativity to build what you think the product should be.

It also centers the process, meaning how problems and solutions are validated, on your users.
