Disciplines
Create the groups, such as Design or Development, that organise people on Schedule and give their rows a shared colour.
Create a discipline here, then assign it to people in Resources.
Add or change a discipline
Select Add discipline, enter a name, choose a preset colour and save. It appears on Schedule once someone is assigned to it, at the end of the schedule's group order. This list stays alphabetical.
Select the edit icon on a row to change its name or colour. A blank name keeps the form open until you correct it.
Remove a discipline
Select the delete icon on its row and confirm Delete discipline? Its people are ungrouped, not deleted, and keep their bookings. They appear in the Unassigned group, or the Studio and Supplementary bands, until you assign another discipline.
Removed the wrong one? Select Undo in the Schedule toolbar to restore it and its grouping.
Turn disciplines off
When the company turns Use disciplines off in Settings, the Disciplines page, its menu link and the Resources form's Discipline field are hidden; /disciplines sends you to Schedule. Nothing is deleted, and turning it back on restores the groups.
