Business interaction refers to the relationships and interactions between different entities or stakeholders within a larger ecosystem. A business ecosystem is a complex network of organizations, individuals, and other entities that interact with each other in order to create, distribute, and consume products and services.
lines may be used to show the relationships and interactions between these components. For example, a line might connect a customer with a supplier to represent the flow of goods or services between the two entities. Similarly, a line might connect a partner with a competitor to represent a strategic alliance or collaboration between the two parties.
