Key Principle of course:
1. The Strategic Role of Ops
“A company’s operations function is
either a competitive weapon
or
a corporate millstone.
It is seldom neutral.” [Skinner ‘69]
S. Chopra/Operations/Strategy

Key Principle of Course:
2. The Process View of Ops
 By
rethinking the IBM Austin assembly plant and
introducing cells,
– distance traveled by a card was cut from 1.5 miles to 200
yards
– floor space was reduced to half
– production tripled with about the same number of workers.
[Chicago Tribune, July 1992]

Operations & the Process View:
What is a Process?
Information
structure
Inputs
Process
Management
Network of
Activities and Buffers
Outputs
Goods
Services
Flow units
(customers, data,
material, cash, etc.)
Labor & Capital
Resources

What defines a “good process”?
Performance: Financial Measures
 Absolute
measures:
– revenues, costs, operating income,
net income
T
Ct
– Net Present Value (NPV) = 
t

Relative measures:
t 0
1  r 
– ROI, ROE
EBIT  Tax
– ROA = Average Total Assets

Survival measure:
– cash flow

Firms compete on product attributes.
This requires process competencies.

Process Competencies are affected by
Process Structure and Management
 Process
structure or architecture:
– (1) inputs and outputs
– (2) flow unit (“jobs”)
– (3) network of activities & buffers
» quantity & location
» precedence relationships
– (4) resource allocation
» capacity & throughput

A Strategic Framework for Operations
 Corporate
Strategy
 Business Unit Strategy
– Sales pitch used by sales (target segments).

Operations Strategy
– What must Operations do particularly well? What
capabilities must Operations develop?

Operations Structure
– How should Operations processes and resources be
structured to develop capabilities and support strategy?
S. Chopra/Operations/Strategy

Wal-Mart
Corporate Strategy
(Gain competitive advantage by) providing customers access to quality
goods, when and where needed, at competitive prices

Wal-Mart (Resulting Benefits)
 Inventory
at retail stores turned over twice a week
(Industry averages once every two weeks)
 Improved targeting of products to markets
 Sales per square foot increased from $102 in 1985 to
$140 in 1991 to $455 in 2002 (Industry average
increased from $102 to $110 to $224)
