Count fewer back-and-forth messages before a task starts, fewer meeting rescopes, and clearer pull requests. Sample journal summaries for recurring blockers that are shrinking. These are early signs communication is landing better, reducing wasteful friction while making collaboration calmer and faster without brute-force pressure that burns people out.
Watch for faster handoffs, kinder code comments, and more cross-functional pairing. Listen for language that moves from blame to curiosity. Notice when new members contribute earlier because norms are legible. These human signals, documented lightly, demonstrate real improvement long before quarterly metrics catch up or leadership decks get updated.
