Marvis Lumber Mill produces large wooden beams for construction. Lately, a labor shortage has caused the amount of direct labor hours to diminish to a point where production will likely fall next quarter. Production supervisors are also worried that one of the saw mills may not make it to the end of the quarter, resulting in a reduction of machine hours.
