Different teams at BonitaSoft work together in documenting and publishing information about Bonita Open Solution.
We have prepared a process diagram which outlines the way we do this.
Check it out on the Community Contributions page here: How to document a new feature.
Here at BonitaSoft, we like to use video tutorials, to show you how to create, use and configure Bonita Open Solution including some extra features included in the Subscription Pack.
The Workflow Patterns initiative has published a set of detailed workflow pattern descriptions to define control flow in process technology. There are also evaluations of which open-source and commercial products support which of these patterns.
