Final answer:
Luis Mayo's position while working on the new breakfast cereal launch at Ralston Purina is described as a member of a venture team. This role is temporary and project-based, bringing together professionals from different departments. After the completion of the project, he will return to his standard role in accounting.
Step-by-step explanation:
Luis Mayo's temporary assignment at Ralston Purina involves working with a group to determine the feasibility of launching a new brand of hot breakfast cereal. Given that he will return to the accounting department after the product launch, his present position is best described by the role that temporarily takes him out of his usual accounting tasks to focus on the project at hand. The correct label for his position in this context would be d) member of a venture team.
A venture team is a group of employees who come together to work on a particular project or to develop a new product, often with members from diverse functional areas bringing in their respective expertise. Since Luis is an accountant, his primary skills are not in product or brand management but in finance and accounting, implying that his contribution to this project is as a specialist rather than a manager in product development or marketing.
Once the project concludes, Luis's role as a member of the venture team will end, and he will return to his primary function in the accounting department, which is typical for roles in venture or project-based assignments.
