Large order quantities
Few customers
Long leadtimes
Non-alligned planning and control
Not sharing Point-Of-Sales (POS) data
Price fluctuations and promotions
Rationing and shortage gaming
Bullwhip Effect
See figure 16.1 page 367
Variations are growing upstream the SCM
due to the lack of co-ordination in
information and materials flow
Can be conducted using
Vendor Managed Inventory VMI
Customer Managed Ordering CMO

Price fluctuations
Temporary sales price changes or sales
promotions
Can increase volumes in the short term, but
Buyers will stop buying when prices are high,
only buying again when discount prices are
offered
Many retailers adopt an everyday low price
The Bullwhip Effect – Time delay
Transfer of demand information in the
supply chain – see figure 16.2 page 369
The changes in the market demand is
registered at the manufacturer with a time
delay
Meaning that the production is short of
materials and then gaining back-orders
When these are delivered – the demand
has lowered again, causing that the
retailer will wait ordering more and so on

Development towards
make-to-order
Make-to-order means that the supplier
can be involved in the process of adding
value in conjuction with customer orders
The time when no value is added often
arises in transisition between sequential
valueadding resources
Examples:
Vola (internal transisition)
Nike (global transition)

2. Driving forces towards increased coopreration in Supply Chain

Uncertain demand
Operative dependency relationships
Outsourcing and transaction costs
2.1 Uncertain demand p 370
Increasing difficulty in predicting future
demand
Ever-shorter product life cycles
Requirements to react faster to market
changes
Increased importance in avoiding time delay –
which means a better
Co-ordination of the flows of information and
materials
2.2 Operative dependency relationships
Companies are increasingly avoiding
different types of buffers
Materials: reduction of stocks
Information: reduction af leadtimes
This tendency will cause strong
dependency relationships
Only possible if it takes place in a spirit of
co-operation between companies
2.3 Outsourcing and
transaction costs pp 371-372
Transactions become more complex and
costly when carried out between external
partners
Example: Orders changed from 100 to 10
pieces per order - the transaction costs
will be multiplied by 10
Be careful when using value-adding
transistions
Use a joint perspective to become efficient

A common inter-organisational process for cross-company material flows
3.1 Customer Managed Ordering CMO
The customer can manage more of the
ordering process himself or
The entire ordering process, meaning that
no order confirmation

Customer
3.2 Vendor Managed Inventory VMI
Who owns the stocks that the vendor is
managing?
Vendor´s deliveries are usually regulated
by an agreement between the parties
Often the vendor will own the stocks
The customer will then be invoiced when
products are withdrawn from the stock
See figure 16.6 page 376

3.3 Quick Respons
Enabling company to react faster to
market changes
Holistic view of the supply chain
Focus on synchronisation
Based on access to and willingness to
exchange information
Point-Of-Sales - POS-system

3.4 Efficient Consumer Respons ECR
A joint initiative by members of the supply
chain to work to improve and optimise
aspects of SCM in order to
Create benefits for the consumer:
Lower prices
More variants
Better availability

3.5 Colaborative Planning Forecasting
and Replenisment CPFR
Aimed at creating collaborative
relationships between suppliers and
customers through
To achieve
Common processes
Structured exchange of information
Increased sales
Cost effectiive material flow
Less tied-up capital
P 380-381
4. Supply Chain Design
Vertically integrated SC
One owner has ownership influence over the
parts of the supply chain
Laterally intergrated SC
Supply Chain structured around several
independent organisations
What a laterally SC gains in core
competence focus and flexibility it may
lose in lack of understanding and control
of the SC as a whole
See figure 16.10 page 382
Figure 16.10

b) Vertical integration – Degree to which a firm directly controls multiple links in the supply chain

Based on APICS (2005)
Examples of Vertical and Lateral
Vertical integration
Zara and Ikea are examples of companies
building their supply chains on vertical
integration to some extent
Lateral integration
SuperBest, Nyt Syn and Sportsmaster are
examples

PUSH and PULL
PUSH
Produces goods in accordance to forecasts
and then PUSHes the goods along the SC
PULL
Starts producing when an order is
received from the customer and deliver in
a short time. The customer is then
PULLing the goods out of the supplier
New ways of designing PUSH/PULL
PULL
PUSH
Physical Efficient SC
Market-Responsive SC
Both Chains require short leadtimes but differ with respect to
•Costs and
•Adaptability
Physical Efficient SC (Lean SC) focus on:
•High utilisation of capacity in production
•Reducing stocks
Market-Responsive SC (Agile SC) focus on:
•Where it is best to have storage and extra production capacity
•How to satisfy the unpredictable demand at the lowest possible cost
