The MBSE Workflow and Collaboration project will define the concepts, requirements, and metrics for an effective systems engineering workflow, its practices and collaboration that support the next generation system modeling language (SysML v2).
Number of design problems found. Cost to fix design problems.
Number of Requirements.  Requirement complexity.
Collaboration (in this context) is defined as 1) sharing common model data & 2) synchronizing tasks.
1) Sharing data can be identified when more than one Role is involved (related to) a Practice (which has an Input, Working or Output Product (SME data sub-set).For example, on a project, this represents two engineers (possibly with different roles) creating, viewing, updating and deleting common SME data simultaneously.
2) Synchronizing tasks are identified when one Practice (with an associated Role) initiates another Practice (which has a different Role associated).  For example, on a project, this represents one engineer completing a task, which then notifies another engineer that they can start their task.
The services for these will collaborations be needed in the SME Model Management concept.
Open question; should practice repository be part of the SME?
