Product development is the creation and launch of products. Product development is a collaborative and interdisciplinary effort that involves cross-functional teams. Product developers often assemble researchers, product designers, marketing specialists, and user experience specialists to help them evolve the product they envision. Stakeholders and early customers provide feedback which help refine the product. Finally once a product is launched, user feedback over a product’s lifecycle helps inform and influence subsequent product development cycles and new iterations of the product.
