Burn-down Chart

a chart that shows the amount of work that is thought to remain in a backlog. Time is shown on the horizontal axis and work remains on the vertical axis. As time progresses and items are drawn from the backlog and completed, a plotline showing work remaining may be expected to fall. The amount of work may be assessed in any of several ways such as user story points or task hours. Work remaining in Sprint Backlogs and Product Backlogs may be communicated by means of a burn-down chart. See also: Burnup Chart

Burn-up Chart

A chart which shows the amount of work which has been completed. Time is shown on the horizontal axis and work is completed on the vertical axis. As time progresses and items are drawn from the backlog and completed, a plotline showing the work done may be expected to rise. The amount of work may be assessed in any of several ways such as user story points or task hours. The amount of work considered to be in-scope may also be plotted as a line; the burn-up can be expected to approach this line as work is completed.

Coherent/Coherence

The quality of the relationship between certain Product Backlog items may make them worthy of consideration as a whole. See also: Sprint Goal.
