What is Supply Chain Management?
SUPPLY CHAIN MANAGEMENT (SCM)
SUPPLY CHAIN
The sequence of organizations – their facilities, functions and activities- that are involving in producing and delivering a product or service.
SCM is a strategic coordination of the supply chain for the purpose of integrating supply and demand management.

Why We need Supply Chain Management???
![Page 8: PRESENT BY : NG SI LING B050810253 LEE WEN HAU B050810183 LIM WENG KEATB050810181 1 SuppliersManufacturersWarehouses & Distribution Centers Customers Material](https://reader036.vdocuments.net/reader036/viewer/2022070407/56649e2d5503460f94b1d324/html5/thumbnails/8.jpg)
Inventory and back-order levels fluctuate considerably across the supply chain even when customer demand doesn’t vary
The variability worsens as we travel “up” the supply chain
Forecasting doesn’t help!

Bullwhip Effect

Demand forecasting practices Min-max inventory management (reorder points to
bring inventory up to predicted levels) Lead time
Longer lead times lead to greater variability in estimates of average demand, thus increasing variability and safety stock costs
Batch ordering Peaks and valleys in orders Fixed ordering costs Impact of transportation costs (e.g., fuel costs) Sales quotas
Price fluctuations Promotion and discount policies
Lack of centralized information

Cost of holding inventory - globally companies are beginning to use 25% of inventory value: Cost of capital Opportunity cost (what we could have done with
the money if we had it in our hands) Obsolescence Storage and handling costs Management and overhead Potential: losses/theft
Why is inventory a waste?

First noticed by Procter & Gamble executives examining the order patterns for Pampers disposable diapers. They noticed that order variation increased dramatically as one moved from retailers to distributors to the factory.
Problem: increases the difficulty of planning at the factory level
Example of the Bullwhip Effect

What is the SOLUTION?
![Page 16: PRESENT BY : NG SI LING B050810253 LEE WEN HAU B050810183 LIM WENG KEATB050810181 1 SuppliersManufacturersWarehouses & Distribution Centers Customers Material](https://reader036.vdocuments.net/reader036/viewer/2022070407/56649e2d5503460f94b1d324/html5/thumbnails/16.jpg)
Reduce uncertainty in the supply chain Centralize demand information Keep each stage of the supply chain provided with up-to-
date customer demand information More frequent planning (continuous real-time planning
the goal) Reduce variability in the supply chain
Every-day-low-price strategies for stable demand patterns
Reduce lead times Use cross-docking to reduce order lead times Use EDI techniques to reduce information lead times
Eliminate the bullwhip through strategic partnerships
Vendor-managed inventory (VMI) Collaborative planning, forecasting and replenishment
(CPFR)16
Four critical methods for reducing the Bullwhip effect:

Uncertainty is inherent to every supply chain Travel times Breakdowns of machines and vehicles Weather, natural catastrophe, war Local politics, labor conditions, border issues
Barriers to integration of organizations Getting top management on board Dealing with trade-offs Small businesses Variability and uncertainty Long lead times

Dealing with uncertain environments – matching supply and demand
Shorter product life cycles of high-technology products
Less opportunity to accumulate historical data on customer demand
Wide choice of competing products makes it difficult to predict demand
The growth of technologies such as the Internet enable greater collaboration between supply chain trading partners
If you don’t do it, your competitor will Major buyers such as Wal-Mart demand a level of “supply
chain maturity” of its suppliers Availability of SCM technologies on the market
Firms have access to multiple products (e.g., SAP, Baan, Oracle, JD Edwards) with which to integrate internal processes 18

Strategy Formulation In the Supply Chain

There are two major step for strategy development in the SCM.
In the first step, managers should prepare the organization for move toward apply SCM strategically.
The second Step is related to the developing strategies and encompassed the following cases:
![Page 23: PRESENT BY : NG SI LING B050810253 LEE WEN HAU B050810183 LIM WENG KEATB050810181 1 SuppliersManufacturersWarehouses & Distribution Centers Customers Material](https://reader036.vdocuments.net/reader036/viewer/2022070407/56649e2d5503460f94b1d324/html5/thumbnails/23.jpg)
Step 1 – Energize the Organization Establishment of SCM and e-Business educational
courses. Ensure top management that supply chain and e-
Business strategies are integrated. Pursue the executive team to act as a sponsor. Enhance the ways in which people work.
Step 2 – Enterprise Vision Defining the nature of the competitive
competencies possessed within the current infrastructure and outside the supply chain network.
Preliminary steps in SCM strategy development

Step 3 – Supply Chain Value Assessment Identify and then prioritize which supply chain
values should be undertaken that would provide the greatest enterprise and trading partner benefits.
Focused on improving core business functions and sustaining the competitive advantages they drive.
Step 4 – Opportunity identification Provide the collaborative with a map of possible
choices for the application of SCM strategies. Detailing and prioritizing the possible supply chain
solution and alternatives

Step 5 – Strategy Decision Focus on expected advantages whether on:
automating and integrating processes reducing costs increasing the flow of information through the supply
chain to amplify existing market realize new ways of providing value to customer

Constructing the Business Value Proposition An effective value proposition must be ready to
respond to three possible service values expected by customer: Super Service (speed and reliable delivery) Variety of Product and Service solutions Mass Customization
Developing the SCM strategy
![Page 27: PRESENT BY : NG SI LING B050810253 LEE WEN HAU B050810183 LIM WENG KEATB050810181 1 SuppliersManufacturersWarehouses & Distribution Centers Customers Material](https://reader036.vdocuments.net/reader036/viewer/2022070407/56649e2d5503460f94b1d324/html5/thumbnails/27.jpg)
Defining the Value Portfolio The following process development need to be
structured to support the business value proposition: Design (product and services) Effective cost management (able to squeeze the time it
takes from idea conception to sales) Services (accompanied with a matrix of value added
services) Quality (standard dimensions of performance and reliability)
Structuring the Scope of Collaboration Decide the scope of the firm’s processes and
activities and level of collaboration with trading partners to supply missing resources and competencies.
![Page 28: PRESENT BY : NG SI LING B050810253 LEE WEN HAU B050810183 LIM WENG KEATB050810181 1 SuppliersManufacturersWarehouses & Distribution Centers Customers Material](https://reader036.vdocuments.net/reader036/viewer/2022070407/56649e2d5503460f94b1d324/html5/thumbnails/28.jpg)
Ensuring Effective Resource Management The enterprise’s resources can be divided into three
major areas: Human knowledge (creation of products, technologies,
systems, processes and relationships) The capital invested in physical assets (warehouses, offices,
information systems, and transportation equipment) The value found in physical assets and human knowledge of
customers, suppliers, and business partners (synchronized delivery and production, outsourcing, and creating collaborative solutions)
SCM Implementation Puts the new strategies, processes and systems to
work according to the project plan in SCM strategy report.

Pursuing Growth Management Structuring a set of meaningful and focused
performance measurements that allow corporate planners to gauge the effectiveness of their supply chain solutions.

Identify whether current setup is helping or hurting your business and to determine how to improve it.
