Question | Answer |
---|---|
change management | Managing the process of implementing major changes in information technology, business processes, organizational structures, and job assignments to reduce the risks and costs of change and optimize its benefits |
conversion | Managing the process of implementing major changes in information technology, business processes, organizational structures, and job assignments to reduce the risks and costs of change and optimize its benefits |
cost benefit anaylsis | Identifying the advantages or benefits and the disadvantages or costs of a proposed solution |
data conversion | Converting data into new data formats required by a new business application and its software and databases. Also includes correcting incorrect data, filtering out unwanted data, and consolidating data into new databases and other data subsets |
documentation | A collection of documents or information that describes a computer program, information system, or required data processing operations |
economic feasibility | Whether expected cost savings, increased revenue, increased profits, and reductions in required investment exceed the costs of developing and operating a proposed system |
end user development | Whether expected cost savings, increased revenue, increased profits, and reductions in required investment exceed the costs of developing and operating a proposed system |
feasibility study | A preliminary study that investigates the information needs of end users and the objectives, constraints, basic resource requirements, cost/benefits, and feasibility of proposed projects |
functional requirements | The information system capabilities required to meet the information needs of end users. Also called system requirements |
Human factors feasibility | Hardware and software capabilities that can affect the comfort, safety, ease of use, and user customization of computer-based information systems |
Implementation process | activities are needed to transform a newly developed information system into an operational system for end users. |
Intangible | The nonquantifiable benefits and costs of a proposed solution or system. |
Postimplementation review | The primary objectives associated with systems maintenance are to correct errors or faults in the system, provide changes to effect performance improvement, or adapt the system to changes in the operating or business environment. |
Project management | enforce a project plan that includes job responsibilities, timelines for major stages of development, and financial budgets |
Legal/political feasibility | includes a thorough analysis of any potential legal ramifications resulting from the construction and implementation of the new system |
Logical model | can be thought of as a blueprint of the current system that displays only what the current system does without regard to how it does it |
Operational feasibility | assessment focuses on the degree to which the proposed development project fits with the existing business environment and objectives with regard to development schedule, delivery date, corporate culture, and existing business processes |
Organizational analysis | is an important first step in systems analysis |
Prototyping | rapid development and testing of working models |
Systems analysis and design | The overall process by which information systems are designed and implemented within organizations |
Systems approach | uses a systems orientation to define problems and opportunities and then develop appropriate, feasible solutions in response |
Systems development life cycle | (1) investigation, (2) analysis, (3) design, (4) implementation, and (5) maintenance. |
Systems implementation | involves hardware and software acquisition, software development, testing of programs and procedures, conversion of data resources, and a variety of conversion alternatives |
Systems maintenance | (1) corrective, (2) adaptive, (3) perfective, and (4) preventive |
Systems specifications | formalize the design of an application’s user interface methods and products, database structures, and processing and control procedures |
System testing | involve testing and debugging software, testing Web site performance, and testing new hardware. An important part of testing is the review of prototypes of displays, reports, and other output |
Systems thinking | to understand a problem or opportunity is one of the most important aspects of the systems approach. Management consultant and author Peter Senge calls systems thinking the fifth discipline |
Tangible | favorable results, such as the decrease in payroll costs caused by a reduction in personnel or a decrease in inventory carrying costs caused by reduction in inventory |
