In which way did network economics play a role in the Girl Scouts solution to their supply chain problems?

The correct choice highlights how network economics influenced the Girl Scouts' approach to their supply chain problems. Network economics refers to the idea that the value of a service or product increases as more people use it; this is particularly relevant in digital solutions where costs are often distributed across a larger user base.

In the context of the Girl Scouts’ solution, the cost per user for their hosted web solution likely decreased as more users adopted the system. This means that the overall operational expenses could be spread over a larger number of transactions or users, making it more economical for the organization. By leveraging a web-based solution, they could provide better access to resources and information across their network, facilitating improved coordination and efficiency throughout their supply chain.

The other options focus on specific technical implementations, such as the centralized database and distribution systems, which may contribute to efficiency but do not directly address the economic aspect of scaling costs in relation to network size and usage, which is central to understanding network economics.
