2. Motivation
Have you experienced problems during integration of MATLAB Simulink models?
Are those people working at different locations, even countries?
Do you feel that your teams develop several times similar stuff, e.g. libraries?
Do you want to adopt agile methodologies?
Are your models complex?
Are there 10+ people working on the same model?

Best practices for modular mode design
Use model reference for unit-level models.
Pick a strategy for grouping units into features.
Avoid algorithmic content at the integration level.
Classify models according to safety requirements.
Use model metrics to monitor unit complexity.
Define the role of model architects and integrators.

Do you know who I´m talking about?
So… why don’t we use some of their approaches?
SOFTWARE ENGINEERING
These problems are not new, there are a lot of engineers that have been struggling for years with them.

Putting your models in version control system
Restore previous versions.
Maintain properly our versions.
Understand all the time what is happening.
Encourage collaboration.
ALL OF THAT JUST BY INTEGRATING PROPERLY A VERSION CONTROL SYSTEM IN YOUR COMPANY

Where are we now at CLAAS
Departments that have developed a modelling process without git, are being trained and will adopt this methodologies in the near future.
Growing number of machine Simulink models are being built on top of git submodules.
Different departments are already working using this methodology.
