Agenda

When firms cooperate, compete and exchange

problems with traditional supply chain management (SCM) problems this creates for

manufacturers problems this creates for their

suppliers problems this creates for consumers

Supply Chain Management Software Who id doing it What is working, what is not…

$ ? Boeing write-off in 1997 due to supply chain inefficiencies

Quiz

A box of cereal spends 104 days in the supply chain

Distorted information causes total inventory in the pharmaceutical supply chain to exceed 100 days. $11 billion in savings to be realized

Poor coordination wasting $ 30 billion annually in the food industry

$ 2.6 billion Boeing write-off in 1997 due to supply chain inefficiencies

Defining SCM

SCM is the coordination of material, information and financial flows between and among enterprises participating in the demand fulfillment process for a product or service.

Spans multiple organizations and industries

Coordination and integration of flows essential for the modern enterprise

A digital nervous system is the corporate, digital equivalent of the human nervous system, providing a well-integrated flow of information to the right part of the organization at the right time. A digital nervous system consists of the digital processes that enable a company to perceive and react to its environment, to sense competitor challenges and customer needs, and to organize timely responses.

Gates: Business @ The Speed of Thought

A digital nervous system requires a combination of hardware and software; it's distinguished from a mere network of computers by the accuracy, immediacy, and richness of the information it brings to knowledge workers and the insight and collaboration made possible by the information.

Scott McNealy on Gates’ View

He is right - I would be very nervous if my systems were based on their platforms and products!

What is the Problem?

The “bullwhip effect” - four key causes Demand signal processing

Currently only order information is shared (not actual sales) Need to instead share POS retail data (sell-through data)

Order batching (retailers only order periodically) Infrequent access to demand information

Order rationing retailers order popular items excessively Hoarding of scare products (inflate demand order of scarce

product to ensure that you have it on-hand)

Special Promotions Alter the normal pattern of product demand from customer;

so that it’s impossible to understand the “true” demand

Interorganizational Systems

Integration of supply chain across companies

Degrees of integration: information, process, property rights

Increased efficiencies through 1. optimal production/logistics planning 2. lower inventories 3. increased flexibility 4. customer satisfaction

Oh brave new world, this is wonderful…But…

But….

Look out for proprietary systems with high specificity Lock-in

Sharing processes is optimal from logistics viewpoint, but remember ‘knowledge of time and place’

Additional information acquired by one party can reduce bargaining power of other. Competitive industries like retailing, grocery and electronics has demonstrated many examples of this….

Solutions to Improve Sales Forecasting

Vendor Managed Inventory Collaborative Forecasting and

Replenishment Quantity-Flexible contracts

(as contrasted with rigid contracts)

Buyer allowed to make limited changes to forecast information, which is then shared with suppliers. Supplier only ships enough for the “newest” forecast. Why is this helpful?

Types of Shared Information

Inventory information Transition to echelon-based inventory systems Upstream companies can determine when and

what to produce Downstream companies can improve service

levels with less inventory The Apple-Fritz Supplier Hub

Fritz manages entire inbound logistics for Apple Consolidates freight, clears customs, manages the

hub, manages local transportation to Apple FLEX system

Types of Shared Information

Sales Data Variance of orders greater than that of sales The “bullwhip effect” - four key causes

Demand signal processing Move to sharing sell-through data and POS retail

data Order batching

Infrequent access to demand information Order rationing

Hoarding of scare products Promotions

Types of Information Sharing

Production/Delivery Schedule Improves due-date estimation Expand planning horizons

Other Information Sharing Performance metrics Capacity information

Models of Information Sharing

Information Transfer Model Transfer information to the other who maintains

the database for decision-making XML, Web Services, EDI, FAX

EDI Limitations Multiple industry-specific standards Rigid design for transaction processing Rigid text formats Batch-oriented Installation costs

Challenges

Aligning incentives of different partners Channel Management Example

Trust and cooperation Confidentiality of shared information Anti-trust implications, such as possible price

fixing behavior Timeliness and accuracy of information Processes, not technology.. Technological constraints
