Describe the stages of new product development

The stages of new product development (NPD) are a structured process that companies follow to bring a new product or service to market. The stages are often referred to as the "product development life cycle" or "NPD process." Here are the typical stages of new product development:

Stage 1: Idea Generation

Stage 2: Idea Screening

Stage 3: Concept Development

Stage 4: Business Case Development

Stage 5: Product Design

Stage 6: Testing and Validation

Stage 7: Production Planning

Stage 8: Launch Planning

Stage 9: Post-Launch Evaluation

Stage 10: Continuous Improvement

Note that these stages are not always linear, and companies may iterate between them or skip certain stages depending on their specific needs and circumstances.
