Lead: When determining the number of employees to fill a job, Labor Management includes a time period leading up to the staffing requirement. For example, a location needs two servers between 11:15 a.m. and 11:30 a.m. If you specify a lead duration of 15, Labor Management determines the location needs two servers starting at 11:00 a.m.
Lag: When determining the number of employees to fill a job, Labor Management includes a time period after the staffing requirement. For example, a location expects a dinner rush from 5:00 p.m. to 8 p.m. Since there are not many dishes to wash at the beginning of the rush, the location needs only one dishwasher from 4:00 p.m. to 6:00 p.m. Labor Management detects a sharp increase in sales from 5:15 p.m. to 5:45 p.m., meaning there are more dirty dishes. Set a lag duration value to staff more dishwashers starting at 6:00 p.m.
