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.

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.
