Job roles are useful when creating Templates if you don't know which team member will eventually perform the task. When you create Work from the Template, you can swap out the Job role placeholders with the team.
Any new task in a Template can be assigned to a Job role.
You can then search and assign the task to any of your practice Job roles.
When you create Work off a template that has specified Job roles, you'll be given the option to assign all tasks that have been allocated Job roles, to colleagues.
In the example here, any tasks in the Template assigned to the 'Bookkeeper' role will be assigned to Pax in the Work, and tasks assigned to the 'Accountant' role will be assigned to Anthony.
If you'd prefer, you can leave the tasks unassigned and allocate them to specific colleagues after the Work has been created.
