element TaskCover

Documentation

A task is a unit of work that has to be scheduled within a certain time window and requires at least one employee. TODO If multiple employees are required to complete a task, it is assumed that they have to work on it at the same time. Similarly, it is not possible to split work on a task across multiple employees (e.g. employee A works the first 30 minutes of a 1 hour task and employee B the second 30 minutes). Employees assigned to a task have to be present for the whole length of the task (if it is split into multiple parts, the same employees have to work on each part).

Properties
This component is not nillable.
