Friedenthal's Metamodel Suggestion (Goals, Critical Success Factors, & Reqts)

["Jeffrey A Estefan" <Jeffrey.A.Estefan@jpl.nasa.gov>]

Frank et al.,

 

Some suggestions from Sandy Friedenthal regarding the development of visual models to reflect the association of Requirements with Goals and Critical Success Factors.   I posed this question to him yesterday following our RA telecon and forwarded a copy of Frank's legend and sample diagram.  [Sandy leads the OMG SysML spec and is the OMG Chair for the Systems Engineering Domain Special Interest Group (SE DSIG).]

 

I think we could produce a visual model that leverages existing UML/SysML diagram elements together with judicious use of stereotypes.  Thoughts?

I suggest that you start with a metamodel of the basic concepts. I believe the  BMM (Business Motivation Metamodel)  through the OMG deals with business goals and I think critical success factors. Once you have the concepts agreed on, then you can map a notation to it.  If we used SysML like notation, we would map the following:

 

OASIS                            SysML                 Notation

Requirement                    Requirement         Class construct with  «requirement»

Goal                               Use case              Oval with «goal»

Critical Success Factor    Property               Rectangle with «csf»

Supports                         Dependency         dashed line with arrowhead and «supports»

Opposes                         Dependency         dashed line with arrowhead and «opposes»

 

Hope all is well.
