2. Use the first story as a benchmark.
3. Compare stories in the first sprint.

What type of information can be easily seen in a cumulative flow diagram?

Information such as backlogged tasks, work in progress, and work completed are easily seen within the diagram. Moreover, the Cumulative Flow diagram can provide deeper insight into potential problems and disruptions in the progress. This insight can be used to make adjustments to the process.
