Answer:
Support activities.
Explanation:
In 1985, Michael E. Porter introduced to the world a value-chain model. The value-chain model describes the set of activities or processes that an organization uses to create value for its consumers by creating a product from just an idea or concept.
Basically, the value-chain activities is a framework for transforming an idea, concept or raw materials into a finished product and then to the end users (consumers).
Michael Porter’s value-chain comprises of five (5) primary activities and these includes; inbound logistics, outbound logistics, service, marketing and sales, and operations. Also, all of these primary activities make use of support activities, represented by a vertical column at the top of the primary activities.
This ultimately implies that, the support activities complements all of the primary activities and they include; procurement, firm infrastructure, technology development and human resources management.
Hence, the investment that Toyota makes in Uber is an investment in support activities of the value-chain model because it involves the procurement of another business to support its logistics.
