THAT THESE SYSTEMS CAN SUPPORT

15

Interactive applications that support decision making; DSS characteristics:

An easy-to-use interactive interface; Models that enable sensitivity analysis,what-if analysis, goal seeking,

and risk analysis; Data from both internal databases and external sources, added to by the

decision maker, who may have insights relevant to the decisionsituation.

DSS applications: Storage; Analytics; Manage performance; Display.

SUPPLY CHAIN & LOGISTICS SUPPORT

19

Definition & components of supply chain;

Description of logistics in context of supply chain;

Attainment of company competitive advantage depends on how well

the supply chain is aligned & managed;

Importance of SCM by discussing Walmarts global sourcing strategy;

Abilities of supply chains to create extended enterprise & RFID for

tracing, monitoring & validating products & materials.

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.

SUPPLY CHAIN & LOGISTICS SUPPORTABILITIES OF SUPPLY CHAINS TO CREATE EXTENDED

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.

PURPOSE & FUNCTIONS OF VIRTUALISATION

27

Storage virtualisation;

Network virtualisation;

Hardware virtualisation.


BMIT5103


BMIT5103


INITIATIVES FOR ADOPTING ENTERPRISE CLOUDS OR PRIVATE CLOUDS

28

Reduce costs to manage software programs and licences; Reduced complexity, lower costs, and improved scalability afforded byenterprise clouds.


BMIT5103


BMIT5103


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.
