+### Calculated value
+
+A Calculated value is a [project attribute](#project-attribute) in OpenProject and available as an [Enterprise add-on](#enterprise-add-on). It enables automatic computations based on formulas using numeric project attributes. This is very helpful for project scoring and evaluation. [Read more about calculated values in our system admin guide](../system-admin-guide/projects/project-attributes/#calculated-value-project-attribute-enterprise-add-on).

+### Watcher
+
+In OpenProject, a watcher is a [user](#user) who receives [notifications](#notifications) about updates or changes to a specific [work package](#work-package), even if they are not the assignee or the accountable. Watching a work package helps users stay informed about its progress, comments, or status changes without actively participating in the task. Users can choose to watch a work package themselves or be added as watchers by other project members with sufficient permissions.

+### Weighted item list
+
+In OpenProject, a Weighted item list can be used both as a [custom field](#custom-field) and as a [project attribute](#project-attribute) and is available as an [Enterprise add-on](#enterprise-add-on). It allows adding items as a hierarchy, together with underlying numerical values. This can be helpful for project evaluation, but also used for other purposes.

 ### Widget
 
 A widget in OpenProject is defined as a small and customizable element that provides relevant information at a glance. Use widgets on your [My page](#my-page) dashboard or on the [project overview](#project-overview). [See all available project overview widgets](../user-guide/project-overview/#available-project-overview-widgets) and read [how to add a widget to the project overview](../user-guide/project-overview/#widgets).
