Operations 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

A Process View

• Physical, durable output

• Output can be inventoried

• Low customer contact

• Long response time

• Capital intensive

• Intangible, perishable output

• Output cannot be inventoried

• High customer contact

• Short response time

• Labor intensive

 Support processes provide vital

resources and inputs to the core processes

Support Processes

TABLE 1.1 | EXAMPLES OF SUPPORT PROCESSES

Capital acquisition The provision of financial resources for the

organization to do its work and to execute its strategy

Budgeting The process of deciding how funds will be

allocated over a period of time Recruitment and hiring The acquisition of people to do the work of

the organization Evaluation and compensation The assessment and payment of people for

the work and value they provide to the company

Human resource support and development The preparation of people for their current

jobs and future skills and knowledge needs Regulatory compliance The processes that ensure that the company

is meeting all laws and legal obligations Information systems The movement and processing of data and

information to expedite business operations and decisions

Enterprise and functional management The systems and activities that provide

strategic direction and ensure effective execution of the work of the business

Operations Strategy

PRIORITIES COST Definition Process Considerations Example

2 Top quality Delivering an outstanding

service or product May require a high level of customer contact and may require

superior product features

3 Consistent

quality Producing services or products that meet design

specifications on a consistent basis

Processes designed and monitored to reduce errors and prevent defects

4 Delivery speed Quickly filling a

customer’s order Design processes to reduce lead time Dell

5 On-time

7 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

Trends in Operations Management

 Productivity improvement

 Global competition

 Ethical, workforce, and environmental

issues

Productivity Improvement

EXAMPLE 1.1

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

600 policies

Productivity Improvement

EXAMPLE 1.1

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

 Calculate the year-to-date labor productivity:

 Calculate the multifactor productivity:

This Year Last Year Year Before Last

= 24.66/hr 112,000

Last Year 2,475,738

= 21.91/hr 113,000

Year Before Last 2,175,447

= $18.91/hr 115,000

Solved Problem 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

labor productivity ratio?

3 credit hours student

Value of inputs = Labor + Materials + Overhead

= $37,500/class

= $4,000 + ($20/student  50 students/class) + $25,000

= $30,000/class

Labor hours of input = 14 hours week 16 weeks class

Labor productivity = = $45,000/class

224 hours/class

Output Input

= 224 hours/class

= $200.89/hour

at $200 each What is the labor productivity ratio of this

manufacturing process?

Value of output = (52 defective  90/defective)

+ (80 garments  200/garment)

= $20,680

= $57.44 in sales per hour
