When two or three flows leave a department and land on tools solving the same problem, you’ve likely uncovered redundancy. Compare feature coverage, switching costs, and integration effort. Often one platform satisfies 80% of needs across teams. Use the diagram to run what-if scenarios, illustrating how a single, negotiated license could reduce spend and complexity. This visual evidence helps groups align on standards without endless debate about personal tool preferences.
Look for thick branches into a vendor that split into very thin usage strands. That shape often hides dormant seats, terminated employees still assigned, or teams that scaled back months ago. Cross-check with HR exits, SSO inactivity, or admin dashboards. Rightsize aggressively, then create alerts tied to inactivity. When your diagram highlights these mismatches, rightsizing becomes non-controversial, because the imbalance between paid capacity and real usage is obvious and hard to dispute.
