Lately, I came across a detailed resource called Burnup chart in Jira by Broken Build while exploring tools that help visualize project progress and improve deadline predictions. This page explains how a burnup chart can track work completed against total scope, helping teams adjust forecasts when there are shifts in project requirements or velocity. It also discusses how these charts allow for early identification of delivery risks by showing progress trends over time. What kinds of challenges have people noticed when trying to rely on burnup charts for deadline estimation?
