Operations Management
Refers to the management of the production system
that transforms inputs into finished goods and services.
Production system: the way a firm acquires inputs then
converts and disposes outputs.
Operations managers: responsible for the transformation
process from inputs to outputs.
Operations management seeks to increase the quality,
efficiency, and responsiveness of the firm.
Seeks to provide a competitive advantage.

Operations Management Concepts
Quality: goods and services that are reliable and
perform correctly.
Quality allows customers to receive the performance that they
expect.
Efficiency: the amount of input to produce a given
output.
Less input required lowers cost and waste.
Responsiveness to customers: actions taken to
respond to customer needs.
Firm can react quickly and correctly to customer needs as they
arise.

Improving Responsiveness to Customers
Without customers, organizations cease to exist.
Non-profit and for-profit firms all have customers.
Managers need to identify who the customer is and their
needs.
What do customers want? Usually customers prefer:
A lower price to a higher price.
High quality over low quality.
Fast service over slow service.
Also good after sale support.
Many features over few features.
Products tailored to their specific needs.

Price v. Attributes
Firms offering high quality, fast service and other
customer desires, often must raise price.
Customers must tradeoff price for attributes.
Operations management tries to push the
price/attribute curve to the right with better production.
Provides more attributes at the same cost.
By enhancing the price/attribute relationship, the firm can
increase its competitive position.

Customer Responsive Production Systems
An output’s attributes is determined by the
production system.
Firms must strike a balance between cost and attributes
Improving Quality: can apply to firms producing
goods and services.
A firm that provides higher quality than others at the
same price is more responsive to customers.
Higher quality can also lead to better efficiency.
Lowers waste levels and operating costs.

Improving Efficiency
Labor productivity allows labor comparisons between
organizations.
Improved efficiency leads to lower costs and better
performance.
TQM and Efficiency: TQM can lead to much higher
labor productivity.
When quality rises, less time is wasted on scrap.
Flexible manufacturing and efficiency: reduces the
set-up costs for production systems.
Facilities layout: seeks to design the machine-worker interface
to increase production efficiency.

Efficient Manufacturing
Most firms face major expense when setting up to
produce a product.
These costs must be paid before production begins.
The more often products to be built change, the higher setup
costs become.
Flexible Manufacturing reduces setup costs.
Just-in-Time (JIT) inventory, while developed for
TQM, also adds to efficient production.
Many costs are reduced including warehousing, holding costs
and inventory tracking.
Firm does not have a supply of parts, but can be vulnerable to
strikes or supply problems.

Efficient Manufacturing
Self-managed teams boost efficiency by allowing for a
flatter organization structure.
The team takes the role of the supervisor.
Teams working together often become very skilled at enhancing
productivity.
Kaizen: Japanese term for a management philosophy
the stresses the need for continuous improvement.
Better operations can come from many, small, continuous
improvements.
Focus on what adds value to the product and try to eliminate
steps that do not add value (such as inspection for defects).

Reengineering
Process Reengineering: the fundamental rethinking
and radical redesign of the business process.
Can boost efficiency by directing efforts to activities that add
value to the good or service produced.
While Kaizen focuses on continuous enhancements, process
reengineering considers wholesale change.
Top managers must support operations enhancement
tools for them to be accepted by workers.
Usually, a successful operations change means a complete
change in the organizational culture.
Without a supporting culture, change will not succeed.
