Answer to Question 1
Organizations have found hundreds of different ways to outsource information systems and portions of information systems.
Some organizations outsource the acquisition and operation of computer hardware. Electronic Data Systems (EDS) has been successful for more than 30 years as an outsource vendor of hardware infrastructure.
Acquiring licensed software is another form of outsourcing. Rather than develop the software in-house, an organization licenses it from another vendor. Such licensing allows the software vendor to amortize the cost of software maintenance over all of the users, thus reducing that cost for all users.
Software as a service (SaaS) is another outsourcing alternative, in which hardware and both operating system and application software are leased. Salesforce.com is a typical example of a company that offers SaaS.
Another outsourcing alternative is to outsource an entire system. PeopleSoft (now owned by Oracle) attained prominence by providing the entire payroll function as an outsourced service. In such a solution, the vendor provides hardware, software, data, and some procedures. The company need provide only employee and work information; the payroll outsource vendor does the rest.
Finally, some organizations choose to outsource an entire business function. For years, many companies have outsourced to travel agencies the function of arranging for employee travel.
