Concept 11 Because open source software is free, it is impossible to make money with it.

Concept 12 Today's system analysts only have a few languages to choose from when creating applications. Concept 13 A component of outsourcing is development of applications outside of the organization. Concept 14 The first administrative information system was developed in the United States by J. Concept 16 When an organization outsources to a company, the company fires the employees of the original organization.

Concept 17 Companies outsource their information systems because they want to reduce their time to market. Concept 18 The city of Grand Rapids Michigan outsourced its computing center in order to better manage its employees. Concept 19 Malaysia is in the bottom ten of countries that organization's use for outsourcing.

Concept 20 If a company chooses to not to outsource their information technology, their only other option is to build the systems in-house. Concept 22 site. Concept 23 Intuit is an example of an IT services firm. Concept 24 Microsoft is the best known software company in the world.

Concept 25 When software companies develop prepackaged software it is called off-the-shelf systems. Concept 26 Oracle is a software company known for productivity software. Concept 29 An example of cloud computing is salesforce. Concept 30 Due to security concerns, cloud computing has experienced decreased growth in recent years. Concept 31 Large organizations do not use open-source software due to a lack of support and maintenance options.

Concept 32 Managed reuse is a less expensive method of managing software reuse.

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.

Synthesis 34 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 downloadd and not built in-house. Synthesis 35 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: The leading software firms and their specialties include: Synthesis 37 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. Synthesis 38 Which of the following is a function of an IT service firm? Concept 39 Which of the following is a firm that specializes in cloud computing?

Concept 41 software solutions consist of a series of integrated modules. Concept 42 Which firm is best known for its ERP software solution? Concept 45 Which solution enables a firm to integrate all parts of a business process into a unified information system? Concept 46 If an organization is using applications rented from a third party vendor running in a remote location, they are most likely using what type of software system?

Concept 47 Why is open source software different than the other types of software? A Companies make money by offering maintenance contracts. B It is available via the Internet. C The source code is free. D Only major corporations offer it. Concept 49 measures the difficulty of loading the software and making it operational.

A Conduct a security background check of the cloud computing organization B Involve the organization's security experts C Clearly define requirements D Perform a risk assessment Answer: Concept 53 Which of the following is NOT an example of open-source software? Concept 54 When an organization has the resources and a system must be built from scratch, an organization should choose what type of software?

Software sources can be categorized as information technology firms, packaged software providers, vendors of ERP software, cloud computing, open source, and the organization itself.

Synthesis 57 Briefly describe why systems development is more difficult now than it was in the past. There was a time, not too long ago, when no systems analysts and no symbolic computer programming languages existed.

Yet people still wrote and programmed applications for computers. Even though today's systems analyst has dozens of programming languages and development tools to work with, systems development is even more difficult now than it was 60 years ago.

Then, as well as even more recently, certain issues were decided for you: If you wanted to write application software, you did it in-house and wrote the software from scratch. Today there are many different sources of software and the focus is no longer exclusively on inhouse development. Instead, the focus will be on where to obtain the many pieces and components that will be combined into the application system.

Code will be written to mainly make all the different pieces work together. Synthesis 58 What are enterprise resource planning systems?

How do they differ from traditional approaches? Identify three enterprise resource planning system vendors. Enterprise resource planning systems integrate individual traditional business functions into a series of modules so that a single transaction occurs seamlessly within a single information system rather than several separate systems. ERP modules focus on business processes rather than on business functional areas.

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 inhouse 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.

Synthesis 60 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. Synthesis 61 Describe the advantages of a company using cloud computing?

Cloud computing is rapidly growing. There are many advantages to engaging in cloud computing. Taking the cloud computing route has its advantages. The top three reasons for choosing to go with cloud computing, all of are 1 freeing internal IT staff, 2 gaining access to applications faster than via internal development, and 3 achieving lower cost access to corporate-quality applications.

Especially appealing is the ability to gain access to large and complex systems without having to go through the expensive and time-consuming process of implementing the systems themselves in-house. Getting your computing through a cloud also makes it easier to walk away from an unsatisfactory systems solution.

Other reasons include cost effectiveness, speed to market, and better performance.

Concept 65 refers to the tasks the software can perform and the mandatory, essential, and desired system features. Concept 67 How does an organization rank criteria for choosing off the shelf software? A Look at cost and then go from there. B Importance depends on the organization's requirements. C The organization chooses the cheapest option. D It does not matter the criteria order as long as ease of installation is considered.
