Why would an analyst need to have an awareness of outsourcing as an alternative to handling IT services in-house?
Analysts need to be aware of outsourcing as an alternative. When generating alternative system development strategies for a system, an analyst should consult with organizations in the area that provide outsourcing services. Perhaps outsourcing the replacement system should be one of your alternatives. Knowing what your system requirements are before you consider outsourcing means that you can carefully assess how well the suppliers of outsourcing services can respond to your needs. However, should you decide not to consider outsourcing, you need to determine whether some software components of your replacement system should be purchased and not built in-house.

Describe how an IT service firm can meet the needs of an organization. Provide an example of an IT service firm.
If a company needs an information system but does not have the expertise or the personnel to develop the system in-house, and a suitable off-the-shelf system is not available, the company will likely consult an information technology services firm. IT services firms help companies develop custom information systems for internal use, or they develop, host, and run applications for customers, or they provide other services. These firms employ people with expertise in the development of information systems. Their consultants may also have expertise in a given business area. Examples of IT firms include IBM, HP, and Computer Sciences Corp.
What is outsourcing? Identify two outsourcing arrangements. Identify two reasons for outsourcing.
Outsourcing is the practice of turning over responsibility of some to all of an organization's information systems applications and operations to an outside firm. A company may hire a third party to develop and run its applications on the third party's computers. Another alternative is for the third party to run the applications on-site and on your computers. Reasons for outsourcing include cost-effectiveness and the company's core mission does not involve managing an information systems unit.
Why would an organization outsource information systems operations?
Outsourcing may be cost-effective. If a company specializes in running payroll for other companies, it can leverage the economies of scale it achieves from running one stable computer application for many organizations into very low prices. Outsourcing also provides a way for firms to leapfrog their current position in information systems and to turn over development and operations to outside staff who possess knowledge and skills not found internally. Other reasons for outsourcing include: freeing up internal resources, increasing the revenue potential of the organization, reducing time to market, increasing process.
What is cloud computing? What are the advantages and disadvantages of using a cloud?
: Cloud computing provides a means for applications to be hosted and run for other companies by a provider. Advantages include less need for internal information technology staff, gaining access to applications faster than internal development, and achieving lower-cost access to corporate-quality applications. Some concerns are reliability, security and compliance with government regulations.

What are the advantages and disadvantages of an ERP system?
The benefits of the enterprise solutions approach include a single repository of data for all aspects of a business process and the flexibility of the modules. A single repository ensures more consistent and accurate data, as well as less maintenance. The modules are flexible because additional modules can be added as needed once the basic system is in place. There are disadvantages to enterprise solutions software. The systems are very complex, so implementation can take a long time to complete. Organizations typically do not have the necessary expertise in-house to implement the systems, so they must rely on consultants or employees of the software vendor, which can be very expensive. In some cases, organizations must change how they do business in order to benefit from a migration to enterprise solutions.
