Objectives can be used to formulate a goal that you want to achieve. An objective have both a description and can be assigned a value or a kano type. The counterpart to a risk is a risk.
A number of stories or epics can be linked to an objective. This means that completing these stories will contribute to achieving this objective. For the advanced use, it is also possible to quantify this contribution with a percentage value, i.e. “this story contributes with 35% of the goal described in this objective (worst-case only 25%)“
Objectives can be viewed and managed primarily from the Storymap view and will often also be included in the Roadmap.
