Which is the final stage in the 5 stages of product and service development?

• A. Design process
• B. Time-to-market
• C. Product Testing
• D. Concept screening

Answer: (D)

In this five-stage framework, the last step is screening concepts to decide which ideas should move forward into development. This stage acts as the final go/no-go checkpoint, ensuring that only concepts meeting strategic fit, feasibility, and market potential proceed to design and execution. Once screening validates a concept, resources are committed for design and testing, leading toward market introduction. The design process belongs earlier, as does product testing which occurs after a concept has been developed, while time-to-market is a consideration that comes after the concept has passed evaluation and is being prepared for launch. So the concluding stage is screening of concepts.
