Open Group IT4IT Reference Architecture Request Rationalization Component

​Purpose

• Rationalize, break down, and route “clean order” requests (ready for fulfillment) to appropriate Fulfillment Execution engines or providers in order to deliver services to consumers. May involve breaking down a single order/request into multiple Fulfillment Requests.
• Ensure appropriate fulfillment-related Subscription information is kept up-to-date, such as approval/rejections, modifications, cancellations, and so on.
• Enable the recording of patterns of service consumption that can be used to shape demand for new and/or improved services.
• Break the request down into the IT services and provide these to the Fulfillment Execution functional component and create the Subscriptions for these services upon their successful fulfillment.
• Fulfillment status is tracked and completion notifications from fulfillment channel(s) are received. Consumers will be able to receive status updates at the Subscription level, not at the level of the underlying requests needed to fulfill the Subscription.
  

Main Functions

• Shall provide information to the consumer on the fulfillment status.
• Shall provide Subscription information for the creation of the associated Chargeback Contract.
• Shall provide information on Request delivery times for SLA measurements.
• Shall break down the composite request (described by the Shopping Cart and consumer-selected values) into the individual Requests that need to be fulfilled.
• Shall send the bound Service Catalog Entry to the Fulfillment Execution functional component in order for it to create the Fulfillment Requests needed to satisfy the order.
