Final answer:
The statement is false; value co-creation relationships in supply management are considered an investment due to their potential to provide long-term benefits like comparative advantage, not just a cost.
Step-by-step explanation:
The statement that as a supply manager, you should view value co-creation relationships as a cost and not an investment, is false. In the context of supply chain management and business relationships, value co-creation is a strategic approach where businesses and suppliers collaborate to develop products or services, which can lead to innovation and competitive advantage. Viewing these relationships as an investment rather than a mere cost recognizes the long-term benefits of strengthened supplier partnerships, enhanced product quality, and shared growth potential. Indeed, anything that can lead to different levels of productivity, such as value co-creation, can be a source of comparative advantage for economies or businesses.
