SUPPLY CHAIN & LOGISTICS SUPPORT
DEFINITION & COMPONENTS OF SUPPLY CHAIN
20
Logisticsis the science concerned with managing material andinformation flows to optimize supply chain operations.
Logistics has been described as having the right thing, at the rightplace, at the right time.

IMPORTANCE OF SCM BY DISCUSSING WALMARTS GLOBAL SOURCING STRATEGY
21
Sourcing involves identifying sources (sellers) that could provideWalmart with products or services to sell in its stores and online;
Its sourcing strategyis designed to reduce costs of goods, increasespeed to market, and improve the quality of products;
Particularly companies in manufacturing, distribution, and retail,SCM is critical to survival.

ENTERPRISE & RFID FOR TRACING, MONITORING & VALIDATING PRODUCTS & MATERIALS
22
IT systems manage and control supply chain management are: ERP; SCM.
RFID is a technology that uses electronic tags (chips) instead ofbarcodes to identify objects or items.

IT INFRASTRUCTURES, CLOUD COMPUTING & SERVICES
DEFINITION OF CLOUD COMPUTING & REASONS FOR USING THE CLOUD
29
Internet-based computing in which shared resources (such as harddrives for storage) and software apps are provided to computers andother devices on-demand, like a public utility;
Reasons for using cloud: Offers a steep drop in IT costs because applications are hosted by
vendors and provided on demand, rather than via physical installationsor seat licenses;
Rental arrangement with vendors.
