Chapter 6 Flashcards
strategic management
the process of determining the strategic vision for the organization
IT governance
a structure of relationships and processes to direct and control the enterprise in order to achieve the enterprise’s goals by adding value while balancing risk versus return over IT and its processes.
IT governance Committee
aligns IT strategy with the business strategy
cascading strategy and goals down into the enterprise
providing organizational structures that facilitate the implementation of strategy and goals
insisting that IT control framework be adopted and implemented
measuring IT’s performance
group of senior managers selected to oversee the strategic management of IT
ISACA
information systems audit and control association
ISO
international organization for standardization
ITIL
information technology infrastructure library
System development life cycle
formal process that many organizations use to select, design, and implement IT systems systems planning systems analysis systems design systems implementation operation and maintenance
systems planning
the evaluation of long term, strategic objectives and the prioritization of the IT systems in order to assist the organization in achieving its objectives
systems analysis
a study of current system to determine the strengths and weaknesses and the user needs of that system
systems design
the creation of the system that meets user needs and incorporates the improvements identified by the systems analysis phase
systems implementation
the st of steps undertaken to program, test, and activate the IT system as designed in the system design phase
operation and maintenance
the regular, ongoing functioning of the IT system and the processes to fix smaller problems, or bugs, in the IT system
conceptual design
the process of matching alternative system models to the needs identified in the system analysis phase
evaluation and selection
process of assessing the feasibility and fit of each of these alternative conceptual approaches and selecting the one that best meets the organization’s needs
software selection
steps to decide which software to purchase
detailed design
the process of designing the outputs, inputs, user interfaces, databases, manual procedures, security and controls, and documentation of the new system
feasibility study(part of the planning)
technical feasibility - assessment of the realism of the possibility that technology exists to meet the need identified in the proposed change to the IT system
operational feasibility - assessment of the realism of the possibility that the current employees will be able to operate the proposed IT system
economic feasibility - assessment of the costs and benefits associated with the proposed IT system
schedule feasibility - schedule feasibility assessment of the realistic possibility that the proposed IT system can be implemented within a reasonable time
systems anlaysis
preliminary investigation - makes a go or no go decision
system survey - study of the current system to identify weaknesses to improve upon and strengths to be maintained
observation
watching the steps that employees take as they process transactions in the system
documentation review
the detailed examination of documentation that exists about the system to gain an understanding of the system under study
interviews
the face to face, verbal questioning of users
questionnaires
written questions of users
business process reengineering
fundamental rethinking and radical redesign of business processes to bring about dramatic improvements
systems design
we go through the process of purchasing the software we need and we fill out a request for proposal
request for proposal
process to solicit proposals
inhouse design
hiring a consultant and making the software in house
conceptual design
involves identifying the alternative conceptual design approaches to systems that will meet the needs identified in the system analysis phase
evaluation and selection
the process of assessing the feasibility and fit of each of the alternative conceptual approaches and selecting the one that best fits the organization’s needs
detailed design
to create the entire set of specifications necessary to build and implement the system
implementation
software programming, training employees, software testing, documenting the system, data conversion, systems conversion
parallel conversion
running both the old and the new system at the same time
direct cutover conversion
deleting the old system and starting the new one
phase in conversion
where the system is broken into parts and phased in over time through each part
pilot conversion
system is operated in one or a few sub units of the organization
user acceptance
means that when the manager of the primary users of the system is satisfied with the system, he will sign an acceptance agreement
post implementation review
a review of the feasibility assessments and other estimates made during the process
operations and maintenance
operating and maintaining the system
stewardship
the careful ad responsible oversight and use by management of the assets entrusted to management
SOX
says that the auditors cannot consult on systems development and design
