Q

5 Approaches to Building Information Systems

A

Traditional Systems Life-Cycle, Prototyping, End-User Development, Application Software Packages and Outsourcing

30
Q

Oldest method of building Info Systems, divided into formal stages maintaining formal division of labor b/t end users and information systems specialists.

A

Traditional Systems Life-Cycle

31
Q

Method of Info System building that builds experimental system rapidly and inexpensively for end users to evaluate a working but preliminary version of IS. Once approved it serves as a template for final system.

A

Prototyping

32
Q

Steps in Prototyping:

A

(1) Identify user requirements (2) Develop initial prototype (3) Use prototype (4) Revise and enhance prototype

33
Q

Advantages and Disadvantages of prototyping?

A

Adv: more likely to fulfill end-user requirements, often used for end user interface design and useful if uncertainty in requirements or design solutions. DisAdv: Can gloss over essential steps, may not accommodate large numbers of data or users, and may not undergo full testing or documentation

34
Q

Method of Info System building that uses fourth-generation languages to allow end-users to develop systems with little or no help from technical specialists

A

End-User Development

35
Q

End-User Development IS building greatest challenge?

A

Managing the process and standards

36
Q

End-User Development IS Advantages?

A

More rapid completion of projects and high-level of user involvement and satisfaction

37
Q

End-User Development IS Disadvantages?

A

Not designed for processing-intensive applications, inadequate management and control, testing, documentation, and loss of control over data

38
Q

Method of Info System building that saves time, money and many offer customization features that modify it to meet requirements without destroying integrity of software?

A

Application Software Packages

39
Q

Application software packages: Detailed list of questions submitted to packaged-software vendors, Used to evaluate alternative software packages based on weights of the criteria

A

Request for Proposal (RFP)

40
Q

Application software packages: Evaluation criteria include several factors, including functions provided by the package, hardware and software resources, vendor quality, cost, etc.

A

Software Package Evaluation

41
Q

Method of Info System building chosen if a firm doesnt want to use its internal resources to build or operate information systems, they ______ the work to an external organization that specializes in providing these services.

A

Outsourcing

42
Q

2 Types of external outsoucing?

A

Domestic and Offshore Outsourcing

43
Q

Advantages of Outsourcing?

A

Allow org flexibility in IT needs

44
Q

Disadvantages of Outsourcing?

A

Hidden Costs, Opening up proprietary business processes to 3rd party.

45
Q

Types of Outsourcing:

A

Cloud and SaaS providers & external vendors.
