An End-to-End solution can refer to a few different concepts depending on the situational context. In one instance, it can be a description of a service or product that requires no additional suppliers in order to meet the buyer’s requirements. Conversely, a solution that only provides limited fulfillment of the buyer’s requirements and requires a third party to complete the system is not considered End-to-End. (similar to turnkey). In the  e-business context, end-to-end can refer to a streamlined, seamless, and real-time flow of information and linkages across a value chain.
