Operations ManagementOperations Management

The systematic design, direction, and control of processes that transform inputs into services and products for internals, as well as external, customers

Processes can be linked together to form a supply chain – interrelated processes within a firms and across different firms that produce a service or product to the satisfaction of the customers

DEFINITIONS, PROCESS CONSIDERATIONS, AND EXAMPLES OF COMPETITIVE PRIORITIES

FLEXIBILITY Definition Process Considerations Example7. Customization Satisfying the unique

needs of each customer by changing service or products designs

Low volume, close customer contact, and easily reconfigured

Ritz Carlton

8. Variety Handling a wide assortment of services or products efficiently

Capable of larger volumes than processes supporting customization

Productivity Improvement: ExampleProductivity Improvement: Example

Calculate the productivity for the following operations:

a. Three employees process 600 insurance policies in a week. They work 8 hours per day, 5 days per week.

SOLUTION

a. Labor productivity = Policies processed

Employee hours

= = 5 policies/hour600 policies

(3 employees)(40 hours/employee)

Productivity Improvement: ExampleProductivity Improvement: Example

Calculate the productivity for the following operations:

b. A team of workers makes 400 units of a product, which is sold in the market for $10 each. The accounting department reports that for this job the actual costs are $400 for labor, $1,000 for materials, and $300 for overhead.

SOLUTION

a. Multifactor productivity = Value of output

Labor cost + Materials cost + Overhead cost

= = = 2.35(400 units)($10/unit)$400 + $1,000 + $300

$4,000$1,700

Problem 1Problem 1

Student tuition at Boehring University is $150 per semester credit hour. The state supplements school revenue by $100 per semester credit hour. Average class size for a typical 3-credit course is 50 students. Labor costs are $4,000 per class, material costs are $20 per student per class, and overhead costs are $25,000 per class.

a. What is the multifactor productivity ratio for this course process?

b. If instructors work an average of 14 hours per week for 16 weeks for each 3-credit class of 50 students, what is the laborproductivity ratio?

Page 27: Chapter 1

1 – 27Copyright © 2010 Pearson Education, Inc. Publishing as Prentice Hall.

Problem 1: SolutionProblem 1: Solution

a. Multifactor productivity is the ratio of the value of output to the value of input resources.

Value of output = 50 studentclass

Value of inputs = Labor + Materials + Overhead

Multifactor productivity = = = 1.25$37,500/class$30,000/class

Problem 1: SolutionProblem 1: Solution

b. Labor productivity is the ratio of the value of output to labor hours. The value of output is the same as in part (a), or $45,000, so

Problem 2Problem 2

Natalie Attire makes fashionable garments. During a particular week employees worked 360 hours to produce a batch of 132 garments, of which 52 were “seconds” (meaning that they were flawed). Seconds are sold for $90 each at Attire’s Factory Outlet Store. The remaining 80 garments are sold to retail distribution at $200 each.

What is the labor productivity ratio of this manufacturing process?

Page 30: Chapter 1

Problem 2: SolutionProblem 2: Solution

Labor productivity = = $20,680

360 hoursOutputInput

Labor hours of input = 360 hours

Value of output = (52 defective 90/defective) + (80 garments 200/garment)

= $20,680

= $57.44 in sales per hour
