TMFS028 Use Case: End to End Modelling of Cloud Based VPN v1.0.0

This use case focuses on the service provisioning design process for government and enterprise services. Before a new product is launched, the OSS team generates the required configuration plan based on the business requirements provided by the BSS, and initiates development, integration, and validation. Once integration testing is successful, the product is made available for commercial activation and sales through the BSS.

The use case adopts a PSR (Product-Service-Resource) modeling approach to design end-to-end service provisioning. It leverages a bottom-up, component-based modeling methodology, decomposing complex government and enterprise business scenarios into reusable service components that can be flexibly composed and configured. This approach significantly reduces redundant development efforts and greatly improves product loading efficiency and time-to-market.
