From management ,ITO is a strategical business innovation . to many corporations, the increase of tecnolgy , demand for high system and the supply to the depose system ,they make the corporation’s aims satisfied and information tecnolgy cost controlled come ture much harder .

1. business

reason of ITO . from theory,anyone should choose SO if it only do with supply at background and don’t create the turnover. a classic example can introduce this problem . according research , 68%in USA credit card business comes ture from uncommercial bank , the bank’core competitive power is finance , it is unnessary to hire too manyweb masters to maintain their web , giving it to web company will be much better.

2.finance

Finance is anther important reason to choose SO, SO can cut down the payment, contrl the cost , rebuild the budget of the information system to solve a part of source for other target , avoid the happening of “IT collapsar” . to those corporations which are no energy to put big money and human power intocorporation information frame costruction starting form hardware base, SO can help them. Acrooding USA forrest research company’s estimate, corporations in America set up a web site and maintain it , the payment is 220000 dollars ,but it’s only 45000 dollars if they give it to professional SO company .j

3. tecnolgy

ITO can get high level information tec worker’s skills , improve tec sevice , supply the choice to connect the new tec ,make internal information tec workers care about core tec moves. Corprations can let the best professional company for them to finish every tach in value chain . for example , trust bank in Australia deal a bargain which is5years limited and 17000000 dollars with hp ,hp manage and maintain trust bank’s IT system ,and help trust to develop new bis----web bank 、elc bank 、personal bank 、 biz bank and so on . If no company like hp , it is hard to finish only on internal information department of the bank.

4.corpration’sstratagem

SO can improve sevice for speed and efficiency ,professional tec workers from SO company can solve the internal information department of corporation from maintain daily , reduce the risk, and improve the department’s honor. , face to a new tecnolgy comes out , most of corporations is hard to use it because of payment and learning , so , ito can draw assistance from SO company and tec in future keeping in-phase , improve tec service , supply the chance to connect new tec, to carry out the function is payed much less ， mumh short time ， much smaller risk in development .

5.human source

Acoording SO , corporation don’t need to make itself human power be large , reduce the energy cost and press because of recruit or person with ability lost . saving the trainning’s cost , and increase flexibility of depoly on human source.

Corporation have many meanning in carrying out ITO : core competitive power , keeping flexibility of copration organizings,improve market competitive, reduce risk ,improve tec sevice,increase cost control, improve and develop in corporatin and so on , but , running SO is not easy , if following the fasion blindfold, and disregard analyse on the risk and keeping away, SO will not bring the prifitbut let the corporation defeat .

research to ITO’s risk is because it has very especial meanning .

One side , the demand can intensify the risk ,coachthecontrl and management , then did it the best , from large side ,acrooding SO , shorten the distance with international top corporation in information tec and management , make them goes well,
