New product development stages with examples

Here are the typical stages of new product development (NPD) with examples:

Stage 1: Idea Generation

Stage 2: Idea Screening

Stage 3: Concept Development

Stage 4: Product Design

Stage 5: Testing and Refining

Stage 6: Launch

These stages are not always linear, and companies may iterate back and forth between them. Additionally, the stages may vary depending on the company, industry, and product.
