Explain why a firm might choose to outsource its information systems (IS) services

A firm might outsource some (or all) of its information systems services for many reasons. Some of these are old reasons, but some are new to today's environment:
• Cost and quality concerns: In many cases it is possible to achieve higher-quality systems at a lower price through economies of scale, better management of hardware, lower labor costs, and better software licenses on the part of a service provider.
• Problems in IS performance: IS departments may have problems meeting acceptable service standards because of cost overruns, delayed systems, underutilized systems, or poorly performing systems. In such cases, organizational management may attempt to increase reliability through outsourcing.
• Supplier pressures: Some of the largest service providers are also the largest suppliers of computer equipment (e.g., IBM or Hewlett-Packard). In some cases, the aggressive sales forces of these suppliers are able to convince senior managers at other organizations to outsource their IS functions.
• Simplifying, downsizing, and reengineering: Organizations under competitive pressure often attempt to focus on only their "core competencies." In many cases, organizations simply decide that running information systems is not one of their core competencies and decide to outsource this function to companies whose primary competency is developing and maintaining information systems.
• Financial factors: When firms turn over their information systems to a service provider, they can sometimes strengthen their balance sheets by liquidating their IT assets.
• Organizational culture: Political or organizational problems are often difficult for an IS group to overcome. However, an external service provider often brings enough clout, devoid of any organizational or functional ties, to streamline IS operations as needed.

• Internal irritants: Tension between end users and the IS staff is sometimes difficult to eliminate. At times this tension can intrude on the daily operations of the organization, and the idea of a remote, external, relatively neutral IS group can be appealing.

Identify and describe the types of ISP service, along with the Internet connection methods, in use today

There are two types of ISP service: narrowband and broadband. Narrowband service is the traditional telephone modem connection now operating at 56.6 Kbps (although the actual throughput hovers around 30 Kbps due to line noise that causes extensive resending of packets). This used to be the most common form of connection worldwide but has been replaced by broadband connections in most of the United States, Europe, and Asia.

Broadband service is based on DSL, cable modem, telephone (T1 and T3 lines), and satellite technologies. Broadband – in the context of Internet service – refers to any communication technology that permits clients to play streaming audio and video files at acceptable speeds – generally anything above .5 Mbps.

Digital Subscriber Line (DSL) service is a telephone technology for delivering high-speed access to the Internet through ordinary telephone lines found in a home or business. Cable Internet refers to a cable television technology that piggybacks digital access to the Internet using the same analog or digital video cable providing television signals to a home. T1 and T3 are international telephone standards for digital communication. These are leased, dedicated, guaranteed lines suitable for corporations, government agencies, and businesses such as ISPs requiring high-speed guaranteed service levels. Additionally, some satellite companies offer high-speed broadband Internet access primarily to homes and offices located in rural areas where DSL or cable Internet access is not available. Access speeds and monthly costs are comparable to DSL and cable.
