A practical guide to uncovering and fixing hidden flow problems by making tasks, blockers and dependencies visible so teams can manage work instead of reacting to it. It identifies common “silent killers” — excessive work-in-progress, frequent interruptions and unplanned work, unclear priorities, and hidden dependencies — and shows how simple visual practices (Kanban-style boards, WIP limits, aging and blocker signals), explicit handoff and triage policies, and basic metrics (cycle time, throughput) reduce context switching, expose bottlenecks and help teams prioritize and finish work reliably.
