The Need for Supply Chain Management
• In the past, organizations did little to manage
the supply chain beyond their own operations
and immediate suppliers which led to
numerous problems:
– Oscillating inventory levels
– Inventory stockouts
– Late deliveries
– Quality problems

What is Operations Management?
“ Operation Management is the set of
activities that create goods and services
through the transformation of inputs into
outputs.”
(Slack, 2001)

Today’s OM Environment

Customers demand better quality,
faster deliveries, and lower costs
20
Competitive Priorities- The Edge


Four Important Operations Questions:
Will you compete on –
Cost?
Quality?
Time?
Flexibility?
All of the above? Some? Tradeoffs?
Source: Reid and Sanders, 2005.
21
Lower prices
(or higher profits)
Faster customer
response
Cost
Speed
Quality
Error-free products
and services
Dependability
On-time
deliveries
Flexibility
Wider variety
More customisation
More innovation
Cope with volume
fluctuations
22
Are There Priority Tradeoffs?




Which priorities are “Order Qualifiers”?
e.g. Must have excellent quality since everyone expects it
Which priorities are “Order Winners”?
e.g. Dell competes on all four priorities
Southwest Airlines competes on cost
McDonald’s competes on consistency
FedEx competes on speed
Custom tailors compete on flexibility
Can you have both high quality and low cost?
e.g. Yes, Coke and Pepsi are good examples
Can you offer design flexibility and short delivery?
e.g. Yes, modular housing manufacturers do it
23
Measuring Productivity

Productivity is a measure of how efficiently inputs are
converted to outputs
Productivity = output/input

Total Productivity Measure
Total Productivity = $sales/inputs $

Partial Productivity Measure
Partial Productivity = cars/employee

Multifactor Productivity Measure
Multi-factor Productivity = sales/total $costs

Highlights




Business Strategy is a long
range plan. Functions
develop supporting plans
Strategy must address
mission, environment, and
core competencies
Business strategy provides a
guide for designing
operations strategy
Operations strategy must
consider which competitive
priorities are essential to
meet business objectives



Competitive priorities are
cost, quality, time, and
flexibility
Productivity measures how
effectively a firm is using
resources
Productivity is computed as
a ratio of outputs divided by
inputs
