Open Group IT4IT Reference Architecture Strategy to Portfolio HPE Implementation

​The Strategy to Portfolio RI includes selected products and integrations which support an end to end use case of creating a proposal to modify an existing service in response to a change in business strategy.
This use case includes the following activities:

• An IT policy and a supporting business objective were defined. 
• A proposal to modify an existing service was created to achieve the business objective. 
• This proposal, along with other items of demand backlog, were evaluated and prioritized. 
• The Expense Management service architecture was modeled in the as-is and to-be state and the service’s architectural gaps were identified, estimated, and a work package of deliverables was created.

The following are the main products and integrations included in this RI:

• UCMDB manages the configuration items of the existing service.
• PPM manages information about the business objective created as a result of a policy change and demand upon the existing service in the form of a proposal to add a mobile channel to access the service.
• PPM is integrated with UCMDB to align the demand to the existing business service.
• EM manages the architectural model elements for the existing service.
• EM integrates with PPM to gain motivational and proposal information impacting the service.
• EM integrates with UCMDB to gain the list of configuration items composing the service.
• Sparx Systems Enterprise Architect is a 3rd party product that models the as-is and to-be states of the service.
• EM integrates with Sparx EA to capture the impacted model elements resulting from a gap analysis between the as-is and to-be models of the service.
