Supply Chain Management
(SCM) Systems


SCM is the process of effectively
managing the components of an
extended value chain--from suppliers,
through manufacturing and distribution
chain, and to the consumers.
SCM information systems use technology to
more effectively manage supply chains
I. What is SCM?
Why Supply Chain
Management?
1950-1980s Manufacturing
Parts

• 50 years ago, U.S. is the only country
that can manufacture cars.
Labor

● You buy a car from GM, all the money
will go to the GM.
1980-2000s Supply Chain
Management
• Today, foreign parts and labors are
much cheaper than that in US.
● You buy a car from GM, only a portion
of money will go to the GM.

From an article published in Harvard
Business Review
Radical business redesign initiatives that
attempt to achieve dramatic
improvements in business processes by
questioning the assumptions, or
business rules of the company.

III. ERP
Enterprise Resource Planning
(ERP) Systems

Enterprise resource planning (ERP) is a
term used to refer to a system that links
individual applications (for example,
accounting and manufacturing
applications) into a single application that
integrates the data and business processes
of the entire business.
Origins of ERP Systems




ERP systems grew out of a function called materials
requirements planning (MRP) which was used to
allocate resources for a manufacturing operation
MRP systems software ultimately became very
complex allowing for efficiencies of scale not
previously possible
Even more sophisticated MRP II systems began to
replace MRP systems in the 1980s
By the early 1990s, other enterprise activities were
being incorporated into ERP systems
Origins of ERP Systems

Today, an ERP system can encompass,
but is not limited to, the following
functions:





Sales and order entry
Raw materials, inventory, purchasing,
production scheduling, and shipping
Accounting
Human resources
Resource and production planning

E-Business and ERP Systems



An e-business must keep track of and process a
tremendous amount of information
Businesses realized that much of the information they
needed to run an e-business — stock levels at
various warehouses, cost of parts, projected shipping
dates — could already be found in their ERP system
databases
A major part of the online efforts of many ebusinesses involved adding Web access to an existing
ERP system
E-Business and ERP Systems


Many e-businesses want the same
things from their business
infrastructure
Thus, rather than custom build
applications, many companies prefer
to use prepackaged ERP system
software, which is often more efficient
and less expensive to implement
Cost of Implementing ERP
Systems



Most businesses need extensive help from
consultants to configure their ERP system
software around their existing business
practices, or to suggest changes in business
practices in order to better fit the ERP system
requirements
This process of mutual adaptation is called
systems integration
The consultants who supervise the
integration process are often referred to as
systems integrators
Outsourcing ERP Systems


One response to the challenge of
managing a complex ERP system is to
outsource it
Some businesses choose to outsource
not only the installation but also the
ERP system software
IV. Supply Chain Systems
Supply Chain Management
(SCM) Systems

A typical SCM system might address the
following issues:





Planning
Vendor selection
Manufacturing
Logistics
Customer relationship

Supply Chain Management
(SCM) Systems



With the advent of the Internet, e-businesses
began to demand different things from their
SCM systems
Most importantly, SCM systems vendors
(largely the same vendors that provide ERP
systems software) had to modify their
products to include a Web-based interface
The ultimate goal of a business ERP system is
complete optimization of internal business
processes
Supply Chain Management
(SCM) Systems



The two basic types of SCM system software are:
Supply Chain Planning software (SCP): uses
mathematical models to predict inventory levels
based on the efficient flow of resources into the
supply chain
Supply Chain Execution software (SCE): is used
to automate different steps in the supply chain such
as automatically sending purchase orders to vendors
when inventories reach specified levels

Customer Relationship
Management (CRM) Systems


Customer relationship management (CRM)
systems, sometimes called e-CRM systems,
use technology to help an e-business manage
its customer base
CRM allows an e-business to match customer
needs with product plans and offerings,
remind customers of service requirements,
and determine what products a customer has
purchased

Data Mining/Web
Mining/Business Intelligence


Data mining is the process of using
mathematical techniques to look for
hidden patterns in groups of data,
thereby discovering previously unknown
relationships among the many pieces of
information stored in a database
A data warehouse is a database that
contains huge amounts of data, such as
customer and sales data

PARTIAL SAP CLIENT LIST
Spacenet
BEFORE SAP R/3
Systems didn’t talk to the extent processes
required, in spite of 20 years of IS labor
 Human glue was required:

to fill-in where systems don’t talk
 to reconcile multiple views of data to arrive at an
“answer”
 to monitor “hold-points” to ensure procedures are
followed amidst the disorganization of being part
paper and part automated
 to bridge systems and paper processes

Formerly Microsoft Business Solutions – Great
Plains
With Microsoft Dynamics, you can bring supply-chain
functions online and make information available for
team collaboration—wherever your employees,
vendors, partners and suppliers are.
Business portal functionality lets you provide supplychain functions, documents, and information to
people across the chain, both inside and outside of
the organization.
And you can use the same portal technology to let
your executives review and augment performance—
when, where, and how they need to.
Why Microsoft Dynamics is for
small businesses?
