The document discusses postponement strategies in supply chain management. It defines postponement strategy as delaying supply chain activities until customer demand is known to balance costs and responsiveness. The main types are purchasing, manufacturing, logistics, and time postponement. Postponement strategies help reduce costs and risks while improving flexibility. Companies implement postponement by having modular product designs and flexible, information-rich operations. The presenter proposes studying postponement strategies through company surveys and case studies.

Grew up in Hong Kong, China
1st year PhD student of the Centre for
Strategy and Performance (CSP)
Dr Ken Platts is my supervisor
This month is my 6th month in Cambridge

3. Struggle
I am struggling in building the conceptual framework
at this moment.
Advices and comments from all of you are welcome
after the presentation.
At any time, be my mentors.

4. The story begins…
While I was having my MPhil thesis viva,
At the end, one panel member suddenly
pointed at a bottle of mineral water in
front of him and asked me

5. “Mr. Wan, what postponement strategy
has been used for making this bottle of
water?”
Let’s think about it…

8. A postponement strategy aims at
delaying some supply chain activities
until customer demand is revealed in
order to maintain both low systemwide
cost and fast response.

9. First suggested by Alderson in 1950
Followed by Bucklin in 1965
Became popular since 1990s (Lee, van Hoek
and Yang)

12. Four Major Strategies
Purchasing postponement
Delay purchasing of some expensive and fragile
materials
Manufacturing postponement
Products in semi-finished forms and can be
customized quickly in production facilities
Logistics postponement
Products in semi-finished forms and can be
customized quickly in production facilities close to
customers
Time postponement
Finished products are kept in central location and are
distributed quickly to customers

20. Other Postponement Strategies
Product development postponement
Delay critical product development decision
Price postponement
Delay the pricing decision until customer demand is known
Postponement of passage of title
Delay the transfer of product ownership from seller to buyer
Demand postponement
Split demand due to capacity constraint

24. Requirements
High product variety
Modular and standardized product design
Flexible manufacturing system
Real time information and communication
Fast response logistics
Strategic supplier relationship

25. Example: A Sony PSP Supply Chain
Products sold in Japan, HK, China and Taiwan
Total number of units sold is roughly estimated
But, the number of units sold in each location is
unknown
Products are highly modular and standardized
Differences in
Manual and packaging (different languages)
Plugs (different sockets)

32. Option 1: Company Level Survey
Collect quantitative data by sending questionnaires
to a large number of target respondents
Employ statistical techniques such as structural
equation modelling or regression to confirm the
causal relationship between
Company capabilities (requirements) and different
postponement strategies
Postponement strategy and competitive advantage
Competitive advantage and organizational performance

36. The story ends…
“Mr. Wan, what postponement strategy
has been used for making this bottle of
water?”
I replied
“Is it the postponement of getting my
degree?”

37. In order not to let the history repeat
itself, your comments are valuable.
Thank you.
