Chapter 11 Objectives
• How do enterprise systems provide value for businesses?
• How do supply chain management systems provide value for businesses? – 11.1.Enterprise systems (p. 380-383)
– 11.2. Supply chain management systems (p. 384-393)
Dr K. ROUIBAH Chapter 11 (QM 240) / dept QM & IS

How Enterprise Systems Work
• ISs that integrate and coordinate key internal processes of the firms, integrating data from different business functions
• Enables data to be used by multiple functions and business processes for precise organizational coordination and control.

Enterprise system architecture

Benefits of Enterprise Systems
• Firm structure and organization: A more uniform organization
• Management: More efficient operations and customer-driven business processes –Firm-wide knowledge-based management processes
• Firm-wide information for improved decision making - Technology: Unified IT platform

The Supply Chain vs. Supply Chain Management (SCM)
Supply Chain• A network of organizations and business processes of procuring
material, transforming raw materials into intermediate and finished products, and distributing the finished product to customers
• Materials, information, and payments flow through the supply chain in both directions.
Supply Chain Management (SCM)
• Coordination of business processes to speed information, product,
and fund flows up and down a supply chain to reduce time,
redundant effort, and inventory costs

Supply Chain Processes
SCOR (Chain Operations Reference Model) identifies five major supply chain processes: • 1-Plan: Balancing demand and supply to meet sourcing,
production, and delivery requirements • 2-Source: Procurement of goods and services needed to create a
product or service• 3-Make: Processes that transform a product into a finished state • Deliver: Processes to manage order transportation and
distribution • 5- Return: Processes associated with product returns
and post delivery customer support
Logistics: Planning and control of all factors that have an impact on the supply chain

Information and Supply Chain Management
Problem of supply chain
• Inaccurate or untimely information causes inefficiencies in supply chain, such as shortages, excessive inventory
• Objective of supply chain management is to overcome bullwhip effect (أثر كرة الثلج)
• There are several solution: Just-in-time
Just-in-time strategy
• Scheduling system for minimizing inventory by having:
• (A) components arrive exactly at the moment they are needed and
• (B) finished goods shipped as soon as they leave the assembly
line
Dr K. ROUIBAH Chapter 11 (QM 240) / dept QM & IS
10
Bullwhip effect
• Distortion of information about the demand for a product as it passes from one entity to the next across the supply chain
Dr K. ROUIBAH Chapter 11 (QM 240) / dept QM & IS

Supply Chain Management Applications [need to find useful examples-based on my background _OR]
Supply chain management systems
• Automate flow of information between company and supply chain partners (suppliers, logistics partners)
Supply chain planning systems
• Generate demand forecasts for a product (demand planning) and help develop sourcing and manufacturing plans for that product
Supply chain execution systems
• Manage the flow of products through distribution centers and
warehouses to ensure that products are delivered to the right
locations in the most efficient manner
• E.g. Agility when it delivers product to Jamayyats in Kuwait
Dr K. ROUIBAH Chapter 11 (QM 240) / dept QM & IS
12
Supply Chain Performance Measurement
Metrics for measuring supply chain performance
• Fill rate (the ability to fill orders by the due date)
• Average time from order to delivery
• The number of days of supply in inventory
• Forecast accuracy
• The cycle time for sourcing and making a product (total elapsed time to complete a business process)

Supply Chain Management Systems (cont’)
Internet-based supply chain management applications:• Provide standard set of tools
• Facilitate global supply chains
• Reduce costs
• Enable efficient customer response
• Allow concurrent supply chains
Two types of demand-driven supply chain management: Push & Pull

Push- versus Pull-Based Supply Chain Models
Dr K. ROUIBAH Chapter 11 (QM 240) / dept QM & IS
16
Supply Chain Management Systems (cont’)
Push-based model • Production master schedules based on forecasts of
demand for products, and products are “pushed” from manufacturer to customers
Pull-based model • Supply chain driven by actual customer orders or
purchases• It is also called demand-driven model or build-to-order

The Future Internet-Driven Supply Chain
The model is not any more sequential …Random

Business Value of Supply Chain Management Systems
• Improved customer service and responsiveness
• Cost reduction
• Cash utilization
