New product development (NPD) is a collaborative and cognitive process for a new product or service development. NPD must meet customers’ needs while achieving business objectives such as growth, profitability, and competitive advantage. The stages of NPD include formatting the opportunity, identification, conception and generation of ideas, design, development, and implementation. Knowledge management encompasses fostering the creation and exchange of ideas among multidisciplinary teams, retaining and preserving accumulated technical knowledge, and capitalising on continuous learning opportunities. For this purpose, tools, platforms, and the application of management practices are necessary to accelerate the development of new products. Therefore, this paper explores an analysis dealing with the intersection between collaborative engineering, knowledge management, and digital technologies for new product development. Initially, collaborative engineering issues are discussed to identify the requirements. Then, how collaborative engineering interconnects with knowledge management will be examined, revealing synergies that enhance knowledge creation, sharing, and practical application throughout the product life cycle. The paper will also address the role of emerging technologies in this dynamic context and their transformative influence on how product development teams collaborate and manage knowledge. Therefore, the article will outline how this convergence of these three elements can accelerate the conceptual development stage of new products.
