Trend line

Definition

A trend line is a graphical representation used in burndown and burnup charts that indicates the general direction in which a project’s progress is moving over time. This line helps visualize patterns in data, such as whether tasks are being completed faster or slower than planned, allowing teams to assess their performance against the project's goals. By highlighting trends, it aids in decision-making and forecasting future performance.

5 Must Know Facts For Your Next Test

1. Trend lines can be either upward or downward, indicating whether the project is ahead or behind schedule.
2. In burndown charts, a downward trend line suggests that the team is completing tasks as expected, while an upward trend line in burnup charts indicates an increase in completed work.
3. The slope of the trend line provides insight into the pace at which work is being completed; a steeper slope means faster progress.
4. Teams use trend lines to identify potential risks early on by observing if the actual performance deviates from the expected trend.
5. Adjustments can be made to project plans based on the analysis of trend lines, allowing teams to pivot when necessary to meet deadlines.

Review Questions
