3Functional Areas Value Chain Perspective
The value chain model, views activities in
organizations as either primary (reflecting the
flow of goods and services) or secondary
(supporting the primary activities). The
organizational structure of firms is intended to
support both of these types of activities.
4Functional Areas Supply Chain Perspective
The supply chain is a business process that links
all the procurement from suppliers, the
transformation activities inside a firm (the
value chain) and the distribution of goods or
services to customers via wholesalers and
retailers.
5Functional Information Systems
Functional information systems support the
organization, processes and business model.
- Composed of smaller systems A functional
information system consists of several smaller
information systems that support specific
activities performed in the functional area. - Integrated or independent The specific IS
applications in any functional area can be
integrated to form a coherent departmental
functional system, they can be integrated across
departmental lines to match a business process or
be completely independent. - Interfacing Functional information systems may
interface internally with each other to form the
organization-wide information system or
externally systems outside the organization. - Supportive of different levels Information
systems applications support the three levels of
an organizations activities operational,
managerial, and strategic

7Supply and Value Chains
Supply chain refers to the flow of materials,
information, payments, and services from raw
material suppliers, through factories and
warehouses (Value Chain), to the final consumer
(Demand Chain). It includes tasks such as
purchasing, payment flow, materials handling,
production planning control, logistics
warehousing, inventory control, and distribution.
When it is managed electronically it is referred
to as an e-supply chain.
- Supply Chain Flows
- Materials flows are all physical products, new
materials, and supplies that flow along the
chain. - Information flows relates to all data associated
with demand, shipments, orders, returns and
schedules. - Financial flows include all transfers of money,
payments, credit card information, payment
schedules, e-payments and credit-related data.
Supply Chains contribute to increased
profitability and competitiveness
8Supply Chains Components
- The supply chain involves three segments
- Upstream, where sourcing or procurement from
external suppliers occur - Internal, where packaging, assembly, or
manufacturing take place - Downstream, where distribution or dispersal take
place, frequently by external distributors. - It also includes the movement of information and
money and the procedures that support the
movement of a product or a service. - Organizations and individuals are also part of
the chain.
9Supply Chains Classifications
- There are several major types of supply chain
- Integrated make-to-stock
- Continuous replenishment
- Build-to-order
- Channel assembly.

10Supply Chain Problems
Adding value along the chain is essential for
competitiveness, however problems exist
especially in complex or long chains and in cases
where many business partners are involved. These
problems are due to uncertainties and the need to
coordinate several activities, internal units,
and business partners.
- Demand forecasts are a major source of
uncertainties - Competition
- Prices
- Weather conditions
- Technological development
- Customer confidence
- Uncertainties exist in delivery times
- Machine failures
- Road conditions
- Shipments
- Quality problems may also create production delays
11Supply Chain Problems continued
The bullwhip effect refers to erratic shifts in
orders up and down the supply chain because of
poor demand forecasting, price fluctuation,
order batching, and rationing within the
chain. Even slight demand uncertainties and
variability become magnified if each distinct
entity, on the chain, makes ordering and
inventory decisions with respect to its own
interest above those of the chain. Distorted
information can lead to tremendous
inefficiencies, excessive inventories, poor
customer service, lost revenues, ineffective
shipments, and missed production schedules.
A common way to solve the bullwhip problem is by
sharing information along the supply chain
through EDI, extranets, and groupware
technologies. For example employing a
vendor-managed inventory (VMI) strategy, the
vendor monitors inventory levels and when it
falls below the threshold for each product this
automatically triggers an immediate shipment.
12Supply Chain Solutions
Information sharing among supply chain partners
(c-commerce) sometimes referred to as the
collaboration supply chain is one method to
overcome problems in the flow. Others are
- Optimal Inventory Levels
- Supply Chain Coordination and Collaboration
- Supply Chain Teams
- Performance Measurement and Metrics
- Various IT-Assisted Solutions
- wireless technology
- optimal shipping plans
- strategic partnerships with suppliers
- just-in-time
13ERP and Supply Chains
Enterprise Resource Planning
ERP or enterprise systems control all major
business processes with a single software
architecture in real time.
- It is comprised of a set of applications that
automate routine back-end operations - such as financial management
- inventory management
- Scheduling
- order fulfillment
- cost control
- accounts payable and receivable,
- It includes front-end operations such as
- POS
- Field Sales
- Service
- It also increases efficiency, improves quality,
productivity, and profitability.

21What is SAP? Systems Applications and Products
in Data Processing
- SAP is the leading global provider of
client/server business application solutions - SAP is the number one vendor of standard business
applications software - SAP is the fifth largest independent software
supplier in the world
22Electronic Commerce
- Interorganizational Systems
- Business-to-business
- Electronic storefront
23Market ExchangeInterorganizational Structure
- Vertical integration
- Multiple activities in the same firm
- Risk range of expertise required
- Selective sourcing
- Some outsourced activities
- Risk control of outsourcer
- Virtual corporation
- Coordination of separate activities
- Risk loss of core competency
24Questions
- Do we benefit from electronic commerce?
- Do we use information to add value to customers?
- Are we managing the product/service channel?
- Have we redesigned business with our partners to
take advantage of technology and provide security - Do we have partners with shared vision and common
purpose? - Do we have the right infrastructure?
25External / Internal Hosting
- Outside (Cheaper)
- minimize bandwidth and hardware problems
- use external experts
- installed infrastructure
- little additional staffing required
- Inside (More Control)
- dependent on third party reliability
- possible single vendor software solutions
- possible single vendor payment scheme
26External / Internal Hosting
- External better at storefronts
- but requires close integration with core business
- Internal better at business to business
- but often creates a self-contained replicated
system that can be outsourced
27Payment
- Credit Cards
- SET (Secure Electronic Transaction) with http
- Electronic Checks
- Public/private key transactions with banks
- Electronic Cash
- 3rd party software to create virtual cash
- EDI/EFT
- Value added network using 3rd party. Common in
business to business.
