An engineer using SysML modeling tool B imports an XMI die produced by SysML modeling tool A (containing a complete model) and makes changes to the model What is the best way XMI provides to introduce the changes back to the original model in the original tool (Tool A)?

• A. Export only the modified and new elements to XMI and import it to Tool A.
• B. Produce a special XMI file expressing the differences from the original XMI and import it into Tool A
• C. Import the entire model back to Tool A as a separate copy and use the tool's diff/merge utility to merge in the changes
• D. Partition the models and exchange parts of the models alter identifying the parts that were changed.

What is a common reason for extending SysML with a profile?

• A. A profile overwrites unwanted SysML concepts and tool-vendor-specific extensions
• B. A profile adds user-specific needs to the model in a systems engineering project
• C. SysML requires the definition of a profile
• D. A profile adds methodology- and domain-specific concepts to SysML.

The lead systems engineer on a project has identified a set of Key Performance Parameters (KPPs) that need to be evaluated both on a periodic basis during development, and during acceptance for everydesign change.
Many of these KPPs are expressed In complex, interrelated differential equations The analysis team has identified appropriate numerical techniques for solving these equations and expressed them in a popular analysis tool.
The lead system modeler and methodologist must ensure that the architecture and design captured in the SysML system model are continuously and accurately reflected In the KPP calculations.
Which strategy is likely to be most successful in accomplishing this?

• A. Use activity and/or state models to accurately model the flow of data to numerically solve the KPP evaluation equations Ensure that the analysis team validates these behavior models Bind each relevant value property within the system model to an activity parameter or state variable such that the KPP evaluation model accurately reflects how the KPPs are derived. Next, use code generation capability inherent in the SysML tool to generate and compile the KPP evaluation routines Recompile and run these routines as needed to update KPP estimates
• B. List the parameters used to evaluate the KPPs in a spreadsheet file. Use the SysML modeling tool's inherent capability to link appropriate value properties to cells in this spreadsheet Task the analysis team with modifying their analysis routines to accept parameters as an input vector from this spreadsheet.
  Ensure that the spreadsheet is updated from the system model prior to each update of the KPP calculations
• C. Work with the analysis team to partition the KPP evaluation model into manageable, reusable subroutines Develop constraint blocks within the SysML model to represent these subroutines, exposing their parameters. Use these new constraint blocks to build a parametric model that ties the KPP evaluation directly to system model element value properties. Leverage available bridging software to link this parametric model to the evaluation subroutines executing in the external analysis tool, and re-evaluate the KPPs on an as-needed basis
• D. Task the analysis learn with recasting each of the KPP equations as constraint blocks and parametric models directly in SysML and linking the resulting parameters to value properties of current system model elements Keeping all information in the same model is the only way to guarantee the consistency the lead engineer has asked for

is it possible to conduct a systems engineering project without applying a methodology?

• A. No. even it r>o formal methodology is applied, working spontaneously is considered to be a methodology
• B. Yes. if only the project's tasks are defined
• C. No. system engineering projects will fail if no dedicated methodology is applied
• D. Yes. it only the project's processes are defined.
