Answer: FALSE 4) An organization may move to outsourcing for political reasons. Answer: TRUE 5) Reducing time to market is one reason for outsourcing. Answer: TRUE 6) A company may consider outsourcing if it feels that its core mission does not involve managing an information systems unit and that it might achieve more effective computing by turning over all of its operations to a more experienced, computer-oriented company. Answer: TRUE 7) Hiring a company to run your applications on your own computers is an example of outsourcing. Answer: TRUE 8) Outsourcing is an alternative analysts need to be aware of.

Answer: Facilitated reuse 115) ________ is the software reuse approach that mandates reuse and measures its effectiveness, as well as mandates that assets be designed for reuse as they are being designed for specific applications. Answer: Designed reuse 116) What is outsourcing? Identify two outsourcing arrangements. Identify two reasons for outsourcing. Answer: 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 a management information systems unit. -31 117) Briefly identify six sources of software. Answer: Software sources can be categorized as hardware manufacturers, packaged software producers, custom software producers, enterprisewide solution providers, application service providers, and in-house developers. Hardware manufacturers are among the largest producers of software. Although, generally not a source of application software, hardware manufacturers are good choices for system software and utilities. Packaged software producers are potential sources of application software. These companies develop software to run on different computer platforms. Custom software producers help firms develop custom information systems for internal use. Custom software producers are often selected when the task requires custom support and the system cannot be built internally. Enterprisewide solutions 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. Enterprisewide solutions are recommended for complete systems that cross functional boundaries. Application service providers are organizations that host and run computer applications for other companies, typically on a per-use or license basis. ASPs are recommended when the supported task is generic, buying and installing the system locally would be too expensive, or for instant access to an application. In-house developers develop the system internally. This method is chosen when resources and staff are available and the system must be built from scratch. 118) What are enterprise resource planning systems? How do they differ from traditional approaches? Identify three enterprise resource planning system vendors. Answer: 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. SAP AG, Oracle, and PeopleSoft, Inc. are three ERP vendors. -35 119) What is cloud computing? What are the advantages and disadvantages of using a cloud? Answer: 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. Page Ref: 35-36 120) Identify the most common criteria for choosing off-the-shelf software. Which two criteria would be among the most important? Answer: The most common criteria are cost, functionality, vendor support, vendor viability, flexibility, documentation, response time, and ease of installation. Cost involves comparing the cost of developing the same system in-house to the cost of purchasing or licensing the software package. Functionality refers to the tasks the software can perform and the mandatory, essential, and desired system features. While vendor support identifies the amount of support the vendor can be expected to provide, vendor viability examines the vendor's marketplace strength. Flexibility refers to the flexibility of customizing the software. The documentation criterion examines issues relating to the user's manual, technical documentation, and cost of acquiring additional copies of the documentation. Response time questions the length of time it takes the software package to respond to the user's requests in an interactive session and how long it takes the software to complete running a job. The ease of installation criterion examines the difficulty of loading the software and making it operational. Vendor support and viability will be among the most important. -39 121) What is software reuse? Briefly describe four approaches to software reuse. Answer: Reuse is the use of previously written software resources, especially objects and components, in new applications. Ad hoc, facilitated, managed, and designed are four approaches to reusing software. With the ad hoc approach, individuals find and develop reusable assets on their own; few, if any, organizational rewards for reusing assets exist. With the facilitated approach, developers are encouraged to practice reuse, but are not required to do so. The managed approach mandates the development, sharing, and adoption of reusable assets. The designed approach mandates reuse, measures its effectiveness, and requires assets to be designed for reuse. -43 122) Identify six sources of software. Briefly describe the internal staffing requirements. Answer: Hardware manufacturers, packaged software providers, custom software providers, enterprise-wide solution vendors, application service providers, and in-house development are sources of software. When software is acquired from hardware manufacturers, the internal staffing requirements vary. When acquiring software from packaged software producers, some IS and user staff are needed to define requirements and evaluate software packages. When choosing custom software, internal staff may be needed, depending on the application. When application service providers are used, ideally internal staff requirements will not be needed. When enterprise-wide solutions are used, some internal staff are necessary, but mostly consultants are needed. If systems are developed in-house, internal staff are necessary, though staff size can vary. 123) How can a company validate purchased software information? Answer: Information about the software can be obtained from the vendor in the form of marketing literature, an RFP, and software documentation. The company can use and test the software on a trial basis; speak with current users of the software, and use independent software testing and abstracting services. -41 124) For each reuse approach, briefly describe its process and policies. Answer: The ad hoc approach does not have a process or policies. The facilitated approach uses incentives, an asset check-in process, and limited review before publication. The managed approach includes a reuse-adapted process, mandated with specific goals; reuse reviews and asset documentation, packaging, and certification guidelines, and specified metrics. The designed approach includes some domain analysis, reuse-oriented architecture, and specific steps to design for and with reuse. -43
