All the deals currently being worked, at various stages, with total dollar value.
Pipeline is the forward view of revenue. It's the sum of all active deals × their stage probability. A well-qualified pipeline lets you forecast next quarter with reasonable accuracy. A bad pipeline (full of stale deals or unqualified opportunities) produces misses. Good sales leadership spends more time on pipeline health than on any other metric.
Pipeline is how you see the future. If pipeline coverage is 1.5x quota, you're almost certainly going to miss. If it's 5x, you're probably fine but inefficient. Healthy is 3-4x quota, with fresh inflow each week.
