This configuration management strategy is likely to be most successful because it allows the engineers to work on the system model collaboratively and concurrently, while maintaining configuration control and avoiding conflicts. A configuration management tool is a software tool that helps manage changes to model elements and track their versions and history. A package is a grouping mechanism that can contain any kind of model element, such as diagrams, blocks, activities, etc. By using a configuration management tool, the engineers can check out packages for editing, which locks the elements in that package and prevents other users from modifying them. The engineers can also view packages in read-only mode by any user at any time, which allows them to see the latest version of the model without affecting it. The engineers can also receive alerts when a package they are viewing has been modified and checked-in by another user, and see the changes highlighted. This way, the engineers can stay informed and synchronized with the model updates. By not allowing packages to remain checked out overnight, the engineers can avoid holding up the work of other users who need toaccess or modify those packages.

The information in option E is necessary and sufficient for the engineering team to begin selecting and procuring COTS components for the embedded real-time control system. This information defines the timing and cost requirements and constraints for the system and its components, which are essential for evaluating and comparing the available COTS components. The other options are either incomplete or irrelevant for this purpose. For example, option A does not include the minimum period of time between critical inputs, the maximum number of critical inputs, or the cost information. Option B does not include the minimum period of time between critical inputs or the maximum number of critical inputs. Option C does not include the maximum number of critical inputs or the allocation of cost to system components. Option D does not include the maximum number of critical inputs.

This tool characteristic is required for this project because it ensures that the modeling tool follows the SysML abstract syntax, which defines the metamodel elements and their semantics. The abstract syntax is essential for ensuring consistency and interoperability between different tools and models. The concrete syntax, which defines the notation and presentation of the elements, can have some deviations as long as they do not affect the meaning or interpretation of the model. For example, a tool can use different colors or shapes for some elements without changing their semantics.

 If a systems modeling tool conforms to the XMI specification and includes the XMI representation of the UML Profile for SysML and the XMI representations of Model Libraries defined by SysML, the tool provides the import and export of both SysML diagrams and model data from one tool to another. XMI (XML Metadata Interchange) is a format specification that enables the interchange of objects and models through an XML formatted file. It is based on a metamodel that defines the abstract syntax and semantics of the model elements. By conforming to the XMI specification, a tool can serialize and deserialize SysML models in terms of XML elements and attributes. The tool can also include the XMI representation of the UML Profile for SysML, which defines the mapping of SysML concepts to UML concepts, and the XMI representations of Model Libraries defined by SysML, which provide predefined types and units for SysML models. This way, the tool can import and export both SysML diagrams and model data from one tool to another, ensuring consistency and interoperability.

A best practice to provide the MARTE information to the engineers who require it is to define a viewpoint and conform views for the engineers. A viewpoint is a specification of a perspective on a model that addresses a set of stakeholder concerns. A view is a representation of a model that conforms to a viewpoint. By defining a viewpoint and conform views for the engineers, the MARTE information can be presented in a way that is relevant and understandable for them.

Two cross-cutting mechanisms within SysML that can be used to establish traceability between the systems model and a UML software model are allocations and stereotypes. Allocations are dependencies that indicate a relationship between elements in different models or domains. Stereotypes are extensions of existing metaclasses that add additional information or semantics to model elements. By using allocations and stereotypes, different aspects of the systems model and the software model can be linked and traced.

OCL stands for Object Constraint Language, which is a standard language for expressing constraints on UML and SysML models. Constraints are used to specify additional rules or conditions that are not directly captured by the modeling elements or their relationships. OCL can be used to define constraints on stereotypes, their properties, or their relationships in a profile.
