To include the minutes to either start or end of a business day, tick the checkbox Includes minutes, and insert the time range for a workday. The length of the working day is calculated and shown in parenthesis to the right of the Working hours label.
Resource assignment option allows to select a Jira field used for task assignment (in task edit dialog) and resource workload calculation. By default, it is Assignee. If your company has a special custom field for resource assignment, then select the field here.
