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

1950-1980s Manufacturing
• 50 years ago, U.S. is the only country that can manufacture cars.
● 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.

Business Process Reengineering
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
![Page 13: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/13.jpg)
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.
![Page 14: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/14.jpg)
![Page 15: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/15.jpg)
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
![Page 16: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/16.jpg)
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
![Page 17: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/17.jpg)
Major ERP Systems
SAP R/3 Oracle PeopleSoft (have been merged by
Oracle) Toyota uses PeopleSoft and SAP
Microsoft Dynamics (formerly Microsoft Business Solutions - Great Plains)
![Page 18: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/18.jpg)
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 e-businesses involved adding Web access to an existing ERP system
![Page 19: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/19.jpg)
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
![Page 20: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/20.jpg)
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
![Page 21: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/21.jpg)
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
![Page 22: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/22.jpg)
IV. Supply Chain Systems
![Page 23: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/23.jpg)
Supply Chain Management (SCM) Systems
A typical SCM system might address the following issues: Planning Vendor selection Manufacturing Logistics Customer relationship
![Page 24: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/24.jpg)

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
![Page 26: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/26.jpg)
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
![Page 27: Introduction to Supply Chain](https://reader036.vdocuments.us/reader036/viewer/2022062304/55cf8efe550346703b97d54b/html5/thumbnails/27.jpg)

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

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

Microsoft Dynamics 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 supply-chain 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.
