This paper proposes that Artificial Intelligence (AI) vendors should prioritise developing knowledge services for designers to improve the product innovation design process in the rapidly changing AI landscape. Emphasising a Knowledge-Based View (KBV), it argues for knowledge and its management as a key competency in design, crucial for product innovation. It explores the interaction of Open Innovation, Knowledge Management, and Foresight in enhancing knowledge delivery for designers, focusing on the importance of speed and accuracy of ideation in product innovation. The paper highlights the role of internal and external knowledge in improving design process outcomes and provides strategy and frameworks for integrating knowledge utilising a knowledge service, aiming to enhance innovation efficiency.
