Delayed Product Differentiation
Increased pressure from market to offer variety
Even in national markets, customers are increasingly asking for different
designs, functionality, etc
Globalization: different markets may have different requirements for the
product, due to differences in taste, language, geography, government
regulations
Technology
Multiple versions of the same product being sold at the same time
Production technologies are able to offer variety
Result: Product Proliferation
What is the impact on production/logistics costs?
Setup costs
Inventory holding costs
How can you still offer variety without increasing your production /logistics
costs?
Delayed Product Differentiation and
Push-Pull Boundary
The point of product differentiation is often the push-pull boundary
Delayed product differentiation enables reductions in demand
uncertainty
Reduced demand uncertainty enables the use of pull systems which
may be cost efficient due to economies of scale
Push Strategy
Pull Strategy
Tailored Postponement
Do not implement postponement for the portion of
demand that is certain
Reductions in processing costs
Implement postponement for only the portion where
the demand is uncertain
Reductions in inventory holding/obsolescence costs
Example: Benetton
Option 1: Dye + knit + distribution for a portion of demand
Option 2: Knit + dye + distribution for the rest
Determine the production quantity (dye + knit) in option 1 for
each color, determine the production quantity (knit) in option 2
Design For Logistics
Product and process design key cost drivers of
product cost
Design for manufacturing used design to
decrease manufacturing costs
Major supply chain costs include transportation
costs, inventory costs, distribution costs
Design For Logistics
Design for logistics uses product design to
address logistics costs
Key concepts of design for logistics
Economic packaging and transportation
Concurrent/parallel processing
Standardization
Economic transportation and
storage
Design products so that they can be efficiently
packed and stored
Design packaging so that products can be
consolidated at cross docking points
Design products to efficiently utilize retail
space
Examples
Ikea
World’s largest furniture retailer
131 stores in 21 countries
Large stores, centralized manufacturing, compactly
and efficiently packed products
Rubbermaid
Clear Classic food containers - designed to fit
14x14” Wal-Mart shelves
Concurrent/ Parallel Processing
Objective is to minimize lead times
Achieved by redesigning products so that
several manufacturing steps can take place in
parallel
Modularity/decoupling is key to implementation
Enables different inventory levels for different
parts

Supplier Integration in product
development
Competitive forces are driving firms to integrate
suppliers into product development
Spectrum of Supplier Integration
None
White Box – Informal integration
Grey Box – Formal integration, with collaborative
teams
Black Box – Interface requirements are given,
product is returned
Supplier Integration
What approach is appropriate?
Determine internal competencies
Determine product development needs
Identify external development and manufacturing needs
If future products have components that require external expertise
and can be separated from other components, a black box
approach makes sense.
If components cannot be separated, a grey box approach makes
sense.
If some expertise can be found in house, a white box approach
might make sense.
The “Bookshelf” Approach
Monitor the development of new technologies
Follow suppliers that have developed expertise
When appropriate, integrate these new technologies
This balances the advantages and disadvantages of
being on the cutting edge:
No need to gain experience with the technology, because
suppliers are doing this for you.
Can introduce the technologies when needed.
Mass Customization
The delivery of a wide variety of customized goods at low cost
The key is modular products and processes, so that customer
requests can be met
Companies need to evolve towards “modular companies”, with
managers ensuring that modules are compatible.
Needs instant, costless, seamless integration of different modules
(components)
Consider National Bicycle
Bikes manufactured based on customer weight, size, selections of
model type, color patterns and components
