This document outlines key concepts in production and operations management. It discusses the importance of effective production, including lower costs, higher quality, and responsiveness to customers. Mass, flexible, and customer-driven production systems are compared. The roles of technology in manufacturing are also examined. Other major topics covered include plant location decisions, production planning and control, inventory management, quality control, and ISO standards.

Learning Goals

3. Production & Operations
Management
• Production: Application of resources such as people and
machinery to convert materials into finished goods and services.
• Production and Operations Management: Managing people
and machinery in converting materials and resources into
finished goods and services.

4. Production Systems

5. • A vital function is necessary for generating money
to pay employees, lenders, and stockholders.
• Effective production and operations management
can:
– lower a firm’s costs of production.
– boost the quality of its goods and services.
– allow it to respond dependably to customer demands.
– enable it to renew itself by providing new products.
Strategic Importance of
the Production Function

6. Mass, Flexible and
Customer-Driven Production
• Mass Production – manufacturing products in
large amounts through standardization,
mechanization and specialized skills.
• Flexible Production – producing smaller
batches using information technology,
communication and cooperation.
• Customer-Driven Production – evaluating
customer demands to link with manufacturer.

7. Technology and The
Production Process
• Robots – reprogrammable machines capable of performing routine
jobs and manipulating material
• Computer-Aided Design and Manufacturing – enables engineers
to design parts and buildings on computer screens faster and with
fewer mistakes.
• Flexible Manufacturing Systems – a production facility that
workers can quickly modify to manufacture different products.
• Computer-Integrated Manufacturing – integrates robots,
computers and other technologies to help workers design products,
control machines, handle materials, and control the production
function.

8. The Location Decision

9. The Job of Production
Managers
Oversee the work of people and machinery to convert inputs
(materials and resources) into finished goods and services.

10. Planning the Production
Process
• Choose what goods or services to offer customers.
• Convert original product ideas into final specifications.
• Design the most efficient facilities to produce those products.

11. • Process layout groups
machinery and equipment
according to their functions.
• Facilitates production of a
variety of nonstandard
items in relatively small
batches.
Process Layout

12. • Product layout sets up production equipment along a product-
flow line, and the work in process moves along this line past
workstations.
• Efficiently produces large numbers of similar items.
Product Layout

13. • A fixed-position layout places the product in one spot, and
workers, materials, and equipment come to it.
Fixed-Position Layout

14. • Customer-oriented layout arranges facilities to enhance the interactions
between customers and a service.
Customer Oriented Layout

15. Make, Buy, or Lease Decision
• Choosing whether to manufacture a needed product
or component in-house, purchase it from an outside
supplier, or lease it.
• Factors in the decision include cost, availability of
reliable outside suppliers, and the need for
confidentiality.
Selection of Suppliers
• Based on comparison of quality, prices, dependability
of delivery, and services offered by competing
companies.
Implementing the
Production Plan

16. Inventory Control
– Perpetual inventory
– Vendor-managed inventory
Just-in-Time Systems
• Improving profits and return on investment by minimizing
costs and eliminating waste through cutting inventory on
hand.
Materials Requirement Planning
• Computer-based production planning system by which a
firm can ensure that it has the correct materials for
production.
Inventory Control

17. Controlling the Production
Process
• Production control creates a well-defined
set of procedures for coordinating
people, materials, and machinery.
1) Planning
2) Routing
3) Scheduling
4) Dispatching
5) Follow-up

18. Gantt Chart

19. PERT Diagram

20. Dispatching
Manager instructs each department on what work to do and the
time allowed for its completion.
Dispatching & Follow-up
Follow-Up
Employees and their supervisors spot problems in the
production process and determine needed changes.

21. • A good or service free of deficiencies.
• Poor quality can account for 20% loss in revenue.
• Benchmarking is the process of analyzing other firms’ best
practices.
• Quality control is measuring goods and services against
established quality standards.
• Many companies evaluate quality using the Six Sigma concept.
– A company tries to make error-free products 99.9997% of the time,
a tiny 3.4 errors per million opportunities.
Importance of Quality

22. • International Organization for Standardization (ISO) - mission
is to promote the development of standardized products to
facilitate trade and cooperation across national borders.
• Representatives from more than 146 nations.
• ISO 9000 series of standards sets requirements for quality
processes.
• Nearly half a million ISO 9000 certificates have been awarded to
companies around the world.
• ISO 14000 series also sets standards for operations that
minimize harm to the environment.
