CHAPTER 6SUPPLY CHAIN MANAGEMENT

Slide 6.2

Learning outcomes Identify the main elements of supply

chain management and their relationship to the value chain and value networks

Assess the potential of information systems to support supply chain management and the value chain.

Slide 6.3

Management issues Which technologies should we deploy for

supply chain management and how should they be prioritized?

Which elements of the supply chain should be managed within and beyond the organization and how can technology be used to facilitate this?

Slide 6.4

SCM – some definitions Supply chain management (SCM) The

coordination of all supply activities of an organization from its suppliers and partners to its customers

Upstream supply chain Transactions between an organization and its suppliers and intermediaries, equivalent to buy-side e-commerce

Downstream supply chain Transactions between an organization and its customers and intermediaries, equivalent to sell-side e-commerce.

Figure 6.1 Members of the supply chain: (a) simplified view, (b) including intermediaries

Slide 6.6

The main strategic thrust of enhancing supply chain is to provide a superior value proposition to the customer.

Efficient customer response is one method for the same.

Improving customer value = improving product quality, customer service quality and/or reducing price and fulfillment times.

Slide 6.7

Efficient Customer Response

Was developed by food retailing business in USA

Since then, has been applied to other products and in other countries.

Table 6.1 Objectives and strategies for effective consumer response (ECR)

Slide 6.9

Using technology to support SCM Early implementation: 1989-1993

PC-based EDI purchasing system Electronic trading gateway:1990-1994

EDI-based but involved a wider range of parties

The move towards Internet commerce: 1996 onwards Provide a lower-cost alternative to

traditional EDI

Slide 6.10

Case Study

BHP Steel – An Australian Firm Its use of PC-based SCM dates back to the

1980s E-business here represents a change of

emphasis rather than a radically new approach

Slide 6.11

A history of SCM at BHP Steel

Early implementation 1989-1993. This was a PC-based EDI purchasing system.

Objectives: reduce data errors to 0, reduce administration costs, improve management control, reduce order lead time.

Benefits included: rationalization of suppliers to 12 major partnerships (accounting for 60%

of invoices). 80% of invoices placed electronically by 1990. 7000 items were eliminated from the warehouse, to be sourced directly

from suppliers, on demand. Shorter lead times in the day to day process– from 10 days to 26 hours

for items supplied through a standard contract and from 42 days to 10 days for direct-purchase items.

Barriers: Mainly technological.

Slide 6.12

Electronic trading gateway 1990-1994

Character Also EDI-based, but involved a wider range of parties both

externally (from suppliers through to customers) and internally (from marketing, sales, finance, purchasing and legal)

Aim Provide a combined upstream and downstream supply chain

solution to bring benefits to all parties Learnings

The difficulty of getting customers involved – only four were involved after 4 years, although an industry-standard method for data exchange was used. This was surprising since suppliers had been enthusiastic adopters. From 1994, there was no further uptake of this system.

Slide 6.13

The move towards Internet commerce 1996 onwards

The Internet was thought to provide a lower-cost alternative to traditional EDI for smaller suppliers and customers, through using a lower-cost value-added network.

Objectives: Extend the reach of electronic communications with supply chain partners. Broaden the type of communications to include catalogue ordering, freight

forwarding and customer ordering. Strategy divided transactions into 3 types:

Strategic (high volume, high value, high risk) – a dedicated EDI line was considered most appropriate.

Tactical (medium volume, value and risk) EDI or Internet EDI was used. Consumer transactions (low volume, value and risk) – a range of lower-cost

Internet-based technologies could be used. Benefits:

One example of the benefits has been reducing test certificates for products from $3 to 30 cents.

Barriers: The main barriers to implementation at this stage have been business issues, i.e.

convincing third parties of the benefits of integration and managing the integration process.

Slide 6.14

A simple model of supply chain An organization’s supply chain can be

viewed from a system perspective as the :

Acquisition of resources (inputs) Transformation {into products and services} (process) Products and services (outputs)

Slide 6.15

Supply chain management can dramatically have an impact on the profitability of a company through reducing operating costs and increasing customer satisfaction and so loyalty and revenue.

Figure 6.2 A typical supply chain (an example from The B2B Company)

Slide 6.17

What is logistics?

Logistics is the time related positioning of resource, or the strategic management of the total supply chain.

Slide 6.18

What is logistics?

Used to refer specifically to the management of logistics or inbound and outbound logistics

Inbound logistics: The management of material resources entering an organization from its suppliers and other partners

Outbound logistics: The management of material resources supplied from an organization to its customers and intermediaries

Push and pull supply chain models

Slide 6.20

The Value Chain

A model that considers how supply chain activities can add value to products and services to be delivered to the customer

Benefits for customers are created by reducing costs and adding value to customers within each element of the value chain and at the interface between elements of the value chain

Slide 6.21

In equation form,

Value = (benefit of each VC activity – its cost) + (benefit of each interface between VC activities – its cost)

Slide 6.22

Electronic communication can be used to enhance the value chain by:

- making value chain activities (eg. Procurement) more efficient

- enabling data integration between activities

Slide 6.23

Internet enables value to be created by gathering, organizing, selecting, synthesizing and distributing information.

Virtual value chain – processing is machine based rather than paper based.

Figure 6.4 Two alternative models of the value chain: (a) traditional value chain model, (b) revised value chain modelSource: Figure 6.4(b) adapted from Deise et al. (2000)

Slide 6.25

Internet technologies can reduce production time and costs by increasing the flow of information as a way to integrate different value chain activities.

Through this the value chain can be made more efficient and services delivered to customers more readily.

Slide 6.26

Restructuring the internal value chain

Some weaknesses in the traditional value chain: Most applicable to manufacturing of physical products It is a one-way chain involved with pushing products

to the customer Does not highlight the importance of understanding

customer needs Does not emphasise the importance of value

networks Deise et al. (2000) adapted a new model

Slide 6.27

Towards virtual organization An organization which uses information

and communication technology to allow it to operate without clearly defined physical boundaries between different functions.

Characteristics: Lack of physical structure Reliance on knowledge Use of communications technology Mobile work Boundaryless and inclusive Flexible and responsive

Slide 6.29

Restructuring the Supply Chain as part of strategy definition for e-business

SCM options can be seen as a continuum between internal control of supply chain elements and external control of supply chain elements through outsourcing.

The two end elements of the continuum are referred to as Vertical Integration and Virtual Integration.

The intermediate situation is referred to as Vertical Disintegration or Supply Chain Disaggregation.

Slide 6.30

Vertical Integration

The extent to which supply chain activities are undertaken and controlled within the organization.

Slide 6.31

Virtual Integration

The majority of supply chain activities are undertaken and controlled outside the organization by third parties.

Slide 6.35

Benefits of applying IS to SCM

Increased efficiency of individual processes Benefit: reduced cycle time and cost per order

Reduced complexity of the supply chain -disintermediation Benefit: reduced cost of channel distribution and sale

Improved data integration between elements of the supply chain Benefit: reduced cost of paper processing

Reduced cost through outsourcing Benefits: lower costs through price competition and reduced

spend on manufacturing capacity and holding capacity. Better service quality through contractual arrangements?

Innovation Benefit: better customer responsiveness.

Slide 6.36

Benefits to buying company/customers

Increased convenience through 24 hours a day, 7 days a week, 365 days ordering

Increased choice of supplier leading to lower costs Faster lead times and lower costs through reduced

inventory holding The facility to tailor products more readily Increased information about products and

transactions such as technical data sheets and order histories

Slide 6.37

IS-supported upstream SCM

The key activities of upstream SCM are procurement and upstream logistics

RFID (radio-frequency identification microchip) Microchip-based electronic tags are used

for monitoring anything they are attached to

Slide 6.38

IS-supported downstream SCM Involves selling direct to customers Operating a strategy of

disintermediation by reducing the role of its branches

Slide 6.39

Outbound logistic management Relates to the expectations of offering

sales through a web site

Slide 6.40

IS Infrastructure for SCM

Its required to deliver supply chain visibility to different parties.

Hence there is a need for an integrated supply chain database with different personalized views for different parties

Slide 6.41

A Typical IS Infrastructure

Applications can be divided into those for planning and those for executing, the supply chain process.

Key feature is the use of a central operational database that enables information to be shared between supply chain processes and applications.

This database is usually part of an ERP system.

Use of internet technologies to deliver information over a TCP/IP protocol
