The Core Commerce Management functional block is responsible for all activities related to the provisioning of main business processes. It manages the catalogue of Product Offers and Products and handles the lifecycle of Product Orders starting from an order creation and following all of the orchestration actions necessary to fulfil the complete order including any assurance activities. This functional block is decoupled from the technical concerns of product delivery. This block may also include Product Inventory Management, Problem Handling, SLA Management, and other related functions such as Product Testing or Agreement Management.

The Core Commerce management functional block contains the SPA components that are related to the product instances managed by users. These include:

• the product catalogue that also contains information about the way the product is composed of the underlying services, and
• the product ordering that captures the initial orders for actions from the user such as provisioning of a new circuit, changes to existing circuit or circuit termination.
• The fault management component enables capturing and dealing with user complaints about the systems, concerning problems with services or other activities such as SSP problems or party information updates.
