Lets Try This! • Fisher Technologies is a small firm that double its dollar contribution to a fixed cost and profit in order to be profitable enough to purchase the next generation of production equipment. Management has determined that if the firm fails to increase contribution, its bank will not make the loan and the equipment cannot be purchased. It the firm cannot purchase the equipment, the limitations of the old equipment will force Fisher to go out of business and, in doing so, puts its employees out of work and discontinue producing goods and services for its customers.

Productivity Challenge: Productivity is the ratio of outputs (goods and services) divided by the inputs (resources such as labor and capital) Productivity = Output Input = Goods and Services Labor and Capital Objective: to improve productivity! OPERATIONS AND PRODUCTIVITY

Definition Efficiency Doing job well- minimum resources/waste Effective doing the right thing. OPERATIONS AND PRODUCTIVITY

How do we increase Productivity? 1. 2. 3. Reduce inputs, constant outputs Increase outputs, constant inputs Resulting to High ROI, lower prices. OPERATIONS AND PRODUCTIVITY 4. High ROI, constant productivity = higher prices

Productivity Measurement Single-factor productivity indicates the ratio of one resource (input) to the goods and services produced (outputs) Multifactor productivity indicates the ratio of many or all resources (inputs) to the goods and services produced (outputs) OPERATIONS AND PRODUCTIVITY

Example Collins Title wants to evaluate its labor and multifactor productivity with a new computerized search system. The company has a staff of four, each working 8 hours per day (for a payroll cost of $640/day) and overhead expenses of $400 per day. Collins processes and closes on 8 titles each day. The new computerized title-search system will allow the processing of 14 titles per day. Although the staff, their work hours, and pay are the same, the overhead expenses are now $800 per day. Use Single-factor productivity. Use multifactor productivity. OPERATIONS AND PRODUCTIVITY

Productivity Variables Management Capital Labor contributes about 10% of the annual increase OPERATIONS AND PRODUCTIVITY contributes about 38% of the annual increase which contributes about 52% of the annual increase.

Which of the following is true about 84% of 100? a. It is greater than 100 b. It is less than 100 c. Its is equal to 100 OPERATIONS AND PRODUCTIVITY

Lets Try This. • At Modern Lumber, Inc. , Art Binley, president and producer of apple crates sold to growers, has been able, with his current equipment, to produce 240 crates per 100 logs. He currently purchases 100 logs per day, and each log requires 3 labor-hours to process. He believes that he can hire a professional buyer who can buy a better-quality log at the same cost. If this is the case, he can increase his production to 260 crates per 100 logs. His laobr-hours will increase by 8 hours per day. – What will be the impact on productivity (measured in crates per labor-hour) if the buyer is hired? OPERATIONS AND PRODUCTIVITY

Problem 2 • Art Binley has decided to look at his productivity from a multifactor (total factor productivity) perspective (refer to Solved Problem 1. 1). To do so, he has determined his labor, capital, energy, and material usage and decided to use dollars as the common denominator. His total laborhours are now 300 per day and will increase to 308 per day. His capital and energy costs will remain constant at $350 and $150 per day, respectively. Material costs for the 100 logs per day are $1, 000 and will remain the same. Because he pays an average of $10 per hour (with fringes), Binley determines his productivity increase as follows: OPERATIONS AND PRODUCTIVITY

Solution Current System with Professional Buyer 300 hrs. @ $10 = 308 hrs @ $10 = $3, 080 100 logs/day 000 Labor: $3, 000 Material: 1, 000 Capital: 350 Energy: 150 Total Cost: $4, 500 580 Multifactor productivity of current Multifactor productivity of OPERATIONS AND PRODUCTIVITY system: = 240 crates/4, 500 = proposed system: = 260 1, $4,
