The greatest advantage to having a clear organizational structure (agreements, circles and roles) in a single place is that it becomes even easier to give transparency on how everyone in the organization is using this structure to perform work.

To get clarity on what Role is doing, Nestr has a simple Kanban board system where everyone can follow Projects organized by status and Tasks per Role and per person.
The possible states of a project are:
In case a project has a due date, the date also shows on the project's summary card.
Projects can only have a single leader (Role or individual action), that is the person to go to if you want a status report, and also the responsible for delivering the project.
If you need to further specify what is needed to conclude the project, you can use Tasks and subtasks inside the project, that can be assigned to other people as well.
Another good practice is to use the built-in comments feed to leave project status updates, also able to mention people using the '@' command, like this:
