When a completely new product is devised by going back to the roots of a problem and thinking about a solution in a different way.

• A. Radical solutions
• B. Incremental improvement
• C. Re-engineer
• D. Redesign

Answer: (A)

Radical innovation arises when you return to the roots of a problem and reimagine the solution from first principles, unbound by existing designs or assumptions. This approach aims for a completely new product by exploring fundamentally different ideas, materials, or technologies and redefining what the product should do. It’s a leap, not a step.

Incremental improvement is about small, gradual gains to an existing product. Re-engineer typically means restructuring a process or system to work better, not necessarily creating something entirely new. Redesign involves changing the form or structure, which may still fall within the same basic concept rather than a true departure.
