Currently а cоmpаny is аble tо meet demand оf 5000 units a month. To do so they utilize 240 labor hours at $25/hour and 20,000 board feet of lumber at a cost of $8/foot. Assume additional labor and materials are available at the same cost. The company is current considering three possible investments. Which of the following 3 option results in the largest improvement in productivity (measured in units/$, based on the data in this question)? Option 1 - a marketing campaign will increase demand for the product by 50% and drive up sales. Option 2 - a design option will reduce the necessary lumber by 25% per unit. Option 3 - a management option will decrease the necessary labor by 50% per unit.
