It's taken a very long time, but the latest, much improved, Model Expert 2020 has now been launched.
It has new ways of displaying what your model contains - dashboards, word clouds and meta-model diagrams
It includes menu options to take you directly to problem elements, connectors and diagrams, showing you the issues and letting you fix them there and then.
Make it straightforward to check work against your modelling standards. At package or diagram level, check against tailored subsets of your best practice modelling.
Define in your model what best practice modelling looks like for your team. Then use that to create your own pop-up help, tailored choices and a simplified User Interface which just apply to specific 'managed packages'. So it's much harder to model poorly.
Sometimes you just want to let people know the best way, but not force them; other times you definitely want to make sure they don't go off piste. The choice is yours.
So no matter how large and complex your model, you can give every member of your modelling team the right level of support for them.
