Change management and model reviews

Functional safety standards, such as ISO 26262, require change and configuration management for all development-related artifacts. Since models are now an integral part of the development of safety-related mechatronic systems, they must also be included in the change management process as “first-class entities.”

LieberLieber LemonTree ensures that model changes are traceable at all times — not only the current status, but also the exact changes between individual versions. Information about which user changed what and when is important for teamwork and indispensable in the field of functional safety.

In addition, LemonTree actively supports the review process: changes are clearly visualized, filtered, and supported with useful additional functions for the review process.

 

 

Core Function
  • Traceable changes: Every model change is clearly displayed and documented.
  • Support for reviews: Changes can be reviewed, commented on, and saved in review configurations.
  • Seamless integration into the review process: Reviews can be paused at any time without losing information when resuming.
  • Review comments as model versions: Comments are written in separate branches and can be merged with LemonTree without changing the productive model.
Benefits For Users
  • Security: All changes to UML or SysML models are precisely documented.
  • Traceability: Every user intervention can be traced exactly in terms of time and content.
  • Efficiency in the review process: Changes are presented in a comprehensible manner, can be filtered, and can be checked at any time.
  • Optimized workflow: Review comments can be maintained and merged in separate model versions.
    Long-term documentation: Changes can be permanently saved and visualized, e.g., via XML export.
Advantages Of LemonTree
  • Audit compliance according to ISO standards
  • Complete change history
  • Merge review comments
  • Checkmarks for reviewed changes
