Of course. ARGOS supports collaborations across diverse teams. There are two most frequent ways that can address this question:
A. Everyone works on the same DMPs and other research plans, but on different descriptions
In this case, each organisation makes its own description(s) in a single DMP or other research plan. That means that the manager (i.e. person responsible for the DMP or other research plan activity) creates a DMP or other research plan in ARGOS and shares it with everyone. If the DMP or other research plan are shared with co-ownership rights, then the people will be able to edit it and add their descriptions at any time during the project. If there is the need to control editing rights of people writing the DMPs or other research plans, then the manager can create the description(s) and share these each time with the team members that are responsible for adding input for the specified descriptions.
B. Everyone works on their own DMP or other research plan and content is later merged into one single DMP or other research plan
In this case, each organisation might work on their own DMP or other research plan for the same project. At one point, you need to decide which DMP or other research plan is going to be the core for the work you perform, share co-ownership between managers of all DMPs or other research plans so they can copy all descriptions of their DMPs or other research plans in this single plan document.
