Characteristics

Couple and coordinate consecutive processes – reducing the need for inventory Changing traditional roles Enabling technologies � Electronic data interchange (EDI) � Electronic funds transfer (EFT) � Item-level coding; bar codes; RFID � POS data collection and tracking

• e.g, Wal-mart’s Retail Link allows > 4,000 suppliers to get POS data through EDI and a web interface.

Grocery industry:

Efficient Consumer Response

Efficient Consumer Response (ECR) is the realization of a

Focus areas: 1. Category Management

• • Product Promotions and • Store Assortment

2. Product Replenishment

simple, fast and consumer driven system, in which all links of the logistics chain work together, in order to satisfy consumer needs with the lowest possible cost (

Apparel Industry:

Quick response

A comprehensive business strategy to continually meet changing

makes effective use of resources and shortens the business cycle throughout the chain from raw materials to consumer

i

closer to selling. Methods: � Improved information flows � standardize recording systems � cooperation along the supply chain

requirements of a competitive market place which promotes responsiveness to consumer demand, encourages business partnerships,

(QR Committee of the American Apparel manufacturers Assoc ation, January 1995).

Aim: lead time reduction (less inventory, more accurate forecasting, less discounting) -- bring assortment planning, design and manufacturing

Vendor-Managed Inventory (VMI) The vendor takes responsibility for inventory replenishment Vendor works to agreed-upon LOS (usually in terms of fill rate) Steps:

1. Assemble data: (M) �

2. Forecast sales (M) 3. Forecast orders (M) 4. Generate replenishment orders (M) 5. Order fulfillment (M)

Expected benefits: �

� Supplier: stronger customer tie; integrated supply chain � Rationale: vendor can pool the risk

Reality: � KMART: 300 ⇒ 50 suppliers, other retailers canceling VMI altogether �

� Limited collaboration

DC withdrawal for DC-level retail VMI POS in store-level retail Storage levels in chemical plants (e.g., Air Products, Synergistics)

Customer (retailer): higher fill rates, reduction in price, reduction in inventory

LOS failures due to forecast failures

Co-Managed Inventory (CMI/JMI)

Emphasis on collaboration Steps:

� Joint business process planning (R+M) � Assemble data: (M) � Forecast sales (R+M) � Forecast orders (R+M) � Generate replenishment orders (R+M) � Order fulfillment (M)

Significant successes But: high costs

Supply Chain Strategies

14 © Yossi Sheffi, MIT14

Role of Trust

When there is none: difficult to collaborate � Requires a detailed contract � Stifles innovation; similar to arms’ length

When it is full: there is no need � Less fear of opportunistic behavior � “Implicit contracts” (based on consistent past

behavior)

Most collaborations: “Trust and verify”

Collaborative Planning, Forecasting and Replenishment (CPFR)

Developed by the Voluntary Inter-industry Commerce Standards Association (VICS) Builds on “best-in-class” VMI and CMI implementations Principles: � Builds on the trading partners’ competencies

(includes several “scenarios”) � Working off a single forecast which imbeds the

retailer’s view (of multiple suppliers’ plans) and the supplier’s view (of multiple retailers’ actions)

� Making the whole supply chain more efficient (optimizing the entire chain)

� Increase in retail sales by 14% �

� Identification of many store locations with significant over-stock � coordination around product

CPFR Pilot Projects: Kimberly Clark and Kmart

Results: Increased in-stock rate from 86,5% to 93.4% without overall increase in inventory levels

Cost avoidance by discovering discrepancies

Unexpected benefits: improvedrollovers and new product introductions

Pre-trial work

Choosing a supplier � Done work with J&J SC folks � Similar culture � Committed to speed without fuss � Wanted to do the project

Setting collaboration objectives � Agreed-upon sales forecast � Developed a scorecard for benefit tracking

Front End Agreement � Expectations � Responsibilities

Problems Encountered –

Technical Alignment of Superdrug & J&J exception criteria � Partner had difficulties aligning the criteria. � Solution: used the S/W vendor to do it.

Visibility of data at Superdrug � Firewall problems, slow response �

Multiple exceptions against single product �

weeks � Solution: software fixed to recognize this

Inconsistent data feeds from supplier � Some bar code inconsistencies

Solution: changed internet provider

A problem with J&J sales forecast manifested itself in all

Problems Encountered –

People & Processes

Time available to work on project � More work then expected initially � Solution: redefined roles and responsibilities

so people focused only on their part Depth of Resource Project Discipline Tracking of benefits � Watching the joint scorecard
