OSLC Architecture Management Scenario: Impact Analysis

Overview

The developer is presented with a change request? or a set of change requests. These may be changes in requirements, test plans or any other external resource that can affect the integrity of the design captured in the AM service provider. The user examines the AM resources to acces the impact of the change.

Pre-conditions

• A requirement motivating a change request has already been processed (linked to the change request and test plan).
• The AM service provider manages the archiecture resources. These existing resources have been established ( CLM Linking).
• Individual architecture resources have various types of links to requirements, test cases, and other resources both within and outside of the AM service provider.
• The change reqest(s) have links to other resources, including AM resources.

Main Flow

The developer starts a new impact analysis, by selecting a pre-defined/configured impact analysis type. An Impact Analysis is policy/rule driven. It can be configured to perform the analysis in different ways, following different link types and resource types.

The developer associates the change request(s) with the impact analysis, and invokes it.

The system starts the impact analysis, based on the rules/policies configured in the impact analysis type.

The developer reads the change request, and identifies the set of requirements and resources that will change. The user requests the list of AM resources that have direct links to/from any of the resources that will change.

As a general rule links between target and source are impacted. However some link types this might not be the case (i.e. owning-project). Policy/rule driven impact analysis should be configurable (specify which link types are part of impact).

The impact analysis creates assessment nodes - with links. (reified statement on link, with info relevant to the impact analysis). [this is similar to the suspect links in Req Pro]

Post-conditions

• A document/report summarizing the impact of the potential change?
• A set of assessment nodes.
