Collaboration depth

Shared boards, Gantt charts, assignment of one or more owners per task, in-task comments with @mentions and a single shared workspace are all evidenced, and dashboards are documented to compile one or more boards into progress, budget and workload overviews, with a portfolio template spanning multiple teams. Capacity surfaces only as an input to AI task assignment, and we found no public information on guest or client access, permission depth or explicit dependency handling, so team-level planning is real but its edges are asserted rather than shown.

Tasks carry assignments, comments, subtasks and dependencies in four types with critical path and automatic planning, and Project Portfolios from Premium aggregate across projects; Guest and External roles, with unlimited free externals from Premium, give client access alongside permission notes like local links not extending access. What tempers it is capacity: the member perspective shows per-person task counts, and we found no public information on workload or capacity planning.
