10303-243 wants to provide traceability to respond to business questions like:

(Who) What organization was used for this simulation/analysis?
What requirement version should be used for this behavior analysis assessment
This method/tool should be used for this requirement verification.
(How) What method/tool was used for this simulation?
What is the delta of the product definition that should be sent for this simulation?
Where was this assumption used for a decision?
Why was this technology used for this component?
Prove that the right analysis result was used for this assumption.
If there is a change to this requirement version what does it impact?
This behavior simulation model should be used for this breakdown element (of thisarchitecture, with these interfaces and these operational scenarios).

Ensure consistent product information models through the different product life cycles and technical disciplines (ref.: results of the ASD SSG “Through life cycle interoperability” WG).
Ensure the smooth evolution and the longevity / upward compatibility of the STEP modular standards.
Speed up the adoption of the STEP based standards, by the proper management of a set of consistent standards, sharing the same principles and common subsets (modules).
Improved decision making for complex products, improved traceability
Improved sharing of modelling and simulation information linked to a Systems Engineeringcontex
