Tasks are the individual units of work that need to be done to for an
organisation,
programme,
project,
sub-project or
change request. Tasks are grouped into sub-groups and ultimately into a
task group.Tasks contain estimates of the duration, effort, start date, end date and progress. These estimates of time and effort are added up into the sub-group or WBS that this task belongs to.Tasks can be allocated to individual users or to groups of users. Users can see the tasks that have been allocated to them in their “My stuff” view and they can then log time against their tasks on their
timesheets.When time is logged on timesheets against a task it updates the actual effort for that task. This actual effort is also added up into the task group this task belongs to.
