Which step in manufacturing involves demonstrating 'proof of concept' and being assessed to determine if the product could be developed safely and effectively?

• A. Quality Assurance
• B. Production
• C. Validation
• D. Development

Answer: (D)

The development stage is where a new idea is first tested for feasibility and potential safety, showing proof of concept and assessing whether it could be developed into a safe and effective product. In this phase, researchers and engineers create initial prototypes or experiments to demonstrate that the concept can work in principle, identify key risks, and gauge whether the product could be produced reliably at a larger scale. This early validation helps decide if pursuing full development is worthwhile.

Quality Assurance focuses on maintaining quality during and after production, ensuring processes meet requirements. Production is the actual manufacturing of the product. Validation comes after development and confirms that processes, equipment, and methods consistently produce outputs that meet predefined specifications.
