It was in 1930s that the position of competitory advantage was foremost mentioned in “ laterality theory ” by Chamberlain ( cited in Xia, Ye, and Cai, 2010 ) . Since so, bookmans and research workers have defined competitory advantage ( CA ) with different significances. Cater ( cited in Alali, 2007 ) thinks that CA would be a alone place that the house could develop compared to its rivals. Bamberger ( cited in Alali, 2007 ) consists CA is a place of high quality in an industry or market. “ Hofer and Schendel think that competitory advantage is the singularity of market positioning an organisation through its allotment of resources comparative to its rivals ” ( Xia, Ye, and Cai, 2010, p.685 ) . From this sort of position, CA frequently resulted from resources and capablenesss ( Colgate, 1998 ) . Colgate believes that resources refer to “ assets, strengths and failings, and stocks of available factors ” ; capablenesss include a serious of marketing procedure, such as merchandise development, market research, trade name direction etc ( Colgate, 1998, p.80 ) . To sum up, competitory advantage is the properties of the endeavor which made itself beyond or better than their rivals in the particular concern.

Sustainable competitory advantage ( SCA ) completes the definition of CA on the position of uninterrupted betterment. Porter ( 1985, p.11 ) believes that “ sustainability is achieved when advantage resists eroding by competitory behaviour ” . Specifically, “ to boot sustainability can merely be produced when the resources and capablenesss are lasting, that is, they do non physically deprecate ” ( Colgate, 1998, p.80 ) .

There are many factors which influenced a house to derive SCA. Kettenger i??cited in Alali,2007i?‰ and his co-workers points there are two classs factors which are environmental factors ( includes industry alterations, political alterations, rival limitations and environment alterations ) and foundation factors ( which means alterations on the undermentioned facets: size, geographic, merchandise range, perpendicular range, organisational base, larning curve, technological resources and information resources ) . Obviously, no affair technological resources or information resources, information engineering plays a important function on deriving SCA.

Case survey of SCA in Wal-Mart and Saudi Aramco:

Wal-Mart

Wal-Mart is an American company which operates a concatenation of section shops and warehouse shops. It is the largest retail merchant company in the universe and it was the universe ‘s largest public corporation by gross ( http: //www.forbes.com/lists/2010/18/global-2000-10_The-Global-2000_Sales.html ) . It operated in 14 states which include UK, Canada, US, Mexico, Brazil, Argentina, Puerto Rico, China etc ( hypertext transfer protocol: //walmartstores.com/AboutUs/246.aspx ) . The application of IT in War-Mart could be summarized in 4 stairss and 2 undertakings ( Chen, Ji, and Kong, 2008 ) .

Stairss:

1969-1979, chiefly focal point on runing internal system

1980-1993, constructing communicating web between shops and central offices

constructing IT system to portion informations with provider to pull off stock list

1994-2001, stressing on E-Commerce

2001-2004, concentrate on adjunct activity sectors

( cited in Chen, Ji, and Kong, 2008 )

Wal-Mart has invested tonss of money in the procedure of IT to obtain competitory advantage. In the twelvemonth of 1987, Wal-Mart ‘s twenty-fifth day of remembrance, the company completed the Satellite Network, the largest private orbiter communicating system in the US which can supply bipartisan voice, informations and one-way picture transmittal between its central offices, shops, regional offices and distribution centre locations. ( hypertext transfer protocol: //walmartstores.com/aboutus/7603.aspx )

Wal-Mart ‘s provider web called Retail Link, which was initiated in 1991. It used to supplying day-to-day gross revenues informations as a information warehouse. The application of Retail Link, by which providers can entree to gross revenues, cargo, orders, returns and other informations about their merchandises selling in Wal-Mart shops. Retail Link has shown the value to both parties by sharing information ( hypertext transfer protocol: //fscavo.blogspot.com/2006/04/inside-peek-at-wal-marts-it-systems.html ) .

By the application of information system, Wal-Mart is ever one measure in front of their rivals. To sum up, distinguished IT capablenesss can rise the organisation ‘s competitory place and get more net incomes than rivals. When the competitory advantage can be continued, organisations build sustainable competitory advantage. ( Xia, Ye, and Cai, 2010 )

Saudi Aramco

Saudi Aramco is the state-owned national oil company of Saudi Arabia. It is the largest oil corporation in the universe with the largest proved petroleum oil militias and production. Oil production started in Saudi Arabia in 1933 when California Arabian Standard Oil Company ( Casoc ) affiliated of Standard Oil of California ( Socal, today ‘s Chevron ) . In 1939, another American company joined in the oil geographic expedition and production called Saudi named Texas Company ( Texaco, portion of Chevron ) . By 1944, Casoc changed its name to Arabian American Oil Company known as Aramco. “ Standard Oil of New Jersey and Socony-Vacuum Oil ( both now Exxon Mobi ) joined Socal and Texaco as proprietors of Aramco in 1948 ” . Later on, these four companies were known as sister companies to ARAMCO. ( Alali, 2007, P. 928 )

Existing Competitive Advantage of Aramco:

The modesty of rough oil and gas is the chief CA of Saudi Arabia. The ownership of Oil conveyance company which covered all over the universe is the other CA of Saudi Arabia. In add-on, Saudi Aramco ‘s terminal capacity can make to 10 oilers per twenty-four hours. Above descriptions are the bing CA of Saudi Arabia. ( Alali, 2007, p.928 )

IT becomes sustainable competitory advantage:

Earlier CASCO started in 1930s as mentioned when there is no basic substructure in the state and even Saudi Arabia has non got unified yet. CASCO planned to build its ain communicating system since they found that the Fieldss are at a distance of 100s of kilometres. Therefore, the basic substructure of IT was set up:

The basic telephone switches

Cabling substructure

Microwave systems

( Alali, 2007 )

By utilizing the IT system, the company minimized travelling and decreased determination devising clip ; improved public presentation and technology attempts. Because the demands of development, Saudi Aramco construct a immense communicating substructure from communicating to calculating and including the procedure and control of workss, oil armored combat vehicles and information ace main road. The IT system is composed by:

Telephone services

Calculating services

Networking services

Wireless communicating service

Satellite connexion service

Internet/Intranet services

Procedure and control services

High Frequency services to pass on with ship over the universe

Other services that support operation in the desert countries

Aramco for rather long clip had its ain Television channel and Radio channel

( Alali, 2007 )

Specifically, there are several grounds for Aramco to construct their communicating substructure and IT system:

1 ) They recognized they need to pass on with other countries where their markets are.

2 ) Aramco was owned by four major companies, those companies wanted to hold a autumn entree to information in Aramco.

3 ) Aramco ‘s installations span a really big country of the east cost of Saudi Arabia, these countries needed to be on contact for determination devising and operation.

( Alali, 2007 )

Similarities & A ; differences:

The evident similarity of the two instances is that companies invest immense money on constructing their ain communicating substructure and IT system. In the interim, these investings bring outstanding public presentation as return. Furthermore, they keep introducing on IT to distinguish themselves from their rivals. It is obvious that the aim was achieved by the application of IT and cooperation with related concern company. Actually, these visual aspects should impute to the belongings of regulating and pull offing IT which means to obtain sustainable competitory advantage, therefore the company can last in a viing environment, .

Because the Wal-Mart is a retailing company, the accomplishment of obtaining SCA is conveying more clients and selling more merchandises. All IT infrastructures used to supply better service to client. For these ground, Wal-Mart lay peculiar emphasis on direction, such as logistic direction, warehouse direction, etc. Otherwise, Saudi Aramco belongs to fabricate, it more focus on bring forthing procedure. All application of IT designed to bettering productiveness, minimising production clip, diminishing cost, etc. So the accomplishment of Saudi Aramco is Price advantage, by control of oil production to acquire more SCA. In short, the accomplishment of acquiring SCA in War-Mart and Saudi Aramco are different, they are direction and control individually.
