The document discusses the key steps in product development:
1) Developing a product description. This serves as the blueprint and should address the target market's needs.
2) Creating a prototype. This allows testing and refining the product concept before commercialization.
3) Testing the prototype. This identifies flaws and gathers feedback to improve the product before launch.
4) Validating market acceptability. This determines if the target market will purchase the product and tests the value proposition. Feedback from potential customers is gathered through marketing research.
