OrgPlannerPro vs Visio for org planning

Visio is deeply capable at diagramming and familiar to Microsoft shops. For reorg planning, though, you want to drag a person to a new manager and instantly see the cost delta, the new span of control, and whether you just created a single point of failure. That's a different job than drawing shapes.

Do I need a Microsoft 365 license?

No. OrgPlannerPro runs in the browser and imports a plain CSV, so anyone on the team can open it without Visio or a desktop install.
