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 associates the change request(s) with the impact analysis, and invokes it. The system performs the impact analysis, based on the rules/policies configured in the impact analysis type.

The analysis is configurablereads 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 changed resources (requirements).

The developer starts with the change request. What requirements are fullfilled by this change request? Follow links (all types) from the change req to the reqs. The user requests the list of AM resources that have direct links to/from any of the changed resources (requirements).

As a general rule links between target and source are impacted. However some link types this might not be the case (impacted-by and impacts).

policy/rule driven - configurable (specify which link types are part of impact).

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.

create accessment nodes - with links. (reified statement on link, with info relevant to the impact analysis).

Post-conditions

• A document summarizing the impact of the potential change?
