Examples of CIs can include individual requirements, software, models, and plans. Link: defined relationship between two items of information. Note that when we refer to following a link from one item to another in the following, this does not imply a specific direction for the link OSLC: Open Services for Lifecycle Collaboration – a defined set of services to enable collaboration between tools using related types of information. PDM user: User of a product data management system, typically a designer or implementer RM user: User of a requirements management system, typically a requirements author or requirements manager Requirement Set: A collection of requirements of similar nature or pertaining to the same function. Impact Analysis: Process of identifying downstream affected product lifecycle artifacts as a result of a change. Satisfaction: The characteristic of sets of information items that one set is necessary and sufficient to satisfy another Traceability: The ability to link product requirements back to stakeholders’ needs and forward to corresponding product lifecycles artifacts. Traceability supports numerous product development activities such as change impact analysis, compliance verification, requirements verification and requirements validation.

Our initial focus is on viewing and accessing the RM tool features from PDM tool environments because we have more control over creating this access than we do trying to access PDM data since each PDM tool interface might be different. ---++ <a name="_Toc253494601"></a><!--[if !supportLists]-->4.1 <!--[endif]-->PDM User Use Cases PDM tool user performs the following operations related to requirements management: <!--[if !supportLists]-->UC1. <!--[endif]-->View requirement or requirement sets <!--[if !supportLists]-->UC2. <!--[endif]-->Create requirement or requirement sets <!--[if !supportLists]-->UC3. <!--[endif]-->Edit requirement or requirement sets <!--[if !supportLists]-->UC4. <!--[endif]-->Link requirement set to a CI in PDM system <!--[if !supportLists]-->UC5. <!--[endif]-->Follow link from a CI to a requirement or requirement set in the RM system <!--[if !supportLists]-->UC6. <!--[endif]-->Display requirement or requirement set linked from a CI <!--[if !supportLists]-->UC7. <!--[endif]-->Carry out traceability analysis <!--[if !supportLists]-->UC8. <!--[endif]-->Decompose a requirement [[#_ftn4][<!--[if !supportFootnotes]-->[3]<!--[endif]-->]] ---++ <a name="_Toc253494602"></a><!--[if !supportLists]-->4.2 <!--[endif]-->RM User Use Cases RM tool user performs the following operations related to product data management: <!--[if !supportLists]-->UC9. <!--[endif]-->View CIs <!--[if !supportLists]-->UC10. <!--[endif]-->Follow link from a requirement to a CI or CI set in the PDM system <!--[if !supportLists]-->UC11. <!--[endif]-->Display CI linked from a requirement or requirement set <!--[if !supportLists]-->UC12. <!--[endif]-->Create a requirements baseline and link It to high-level CI in the PDM system <!--[if !supportLists]-->UC13. <!--[endif]-->Carry out traceability analysis from requirements to CIs <!--[if !supportFootnotes]--> --- <!--[endif]--> <div id="ftn1"> </div>
