Final answer:
Radical innovation is the type that requires significant change in thinking, leading to fundamental shifts and new developments in products or industries.
Step-by-step explanation:
The type of innovation that relies on significant change in thinking is known as radical innovation. Unlike incremental or continuous development, which focus on gradual improvements and refinements to existing practices or products, radical innovation involves a fundamental shift and often leads to the creation of completely new products, services, or markets that change existing industries or create entirely new ones. Disruptive innovation, while similar to radical in its impact, specifically refers to an innovation that reshapes an existing market by displacing established market leaders.
