Block 2 Flashcards
Creating conditions for success in IT systems
organisation
Where technology is located to form the IT system, and how activities are organised.
participation
Involvement of users at each stage of systems design – Technical and organisational aspects.
emancipatory
An approach to systems development helping to overcome human well-being constraints (physical, psychological, social conditions or forces).
critical
Approaches looking at issues of power and provide tools to reshape society and put power in the hands of the disadvantaged.
agency
Capacity for action to human beings on a common-sense basis.
captology (CAPT)
Computers As Persuasive Technologies; Refers to the study of computers as persuasive technologies.
persuasive technology
Technologies designed to change people’s attitudes and behaviours.
method
A particular procedure for accomplishing or approaching something.
methodology
The study of methods involving the analysis and assessment of methods to select appropriate methods to achieve planning success.
IS methodology
The study of the methods by which IS projects of all kinds are accomplished.
waterfall
Comprising of several stages: Feasibility study, system investigation, system analysis, system design,implementation, and review and maintenance. Each stage in sequence.
Operational Research
A method of approach whereby looking at the whole system first and considering whether altering the factors directly involved in the problem posed will affect other parts of the system.
Systems Development Life Cycle (SDLC)
A procedural interpretation of the logical stages considered necessary to ensure a successful IS innovation. (Another label for Waterfall Cycle).
Soft Systems Methodology (SSM)
An approach to organisational process modelling and can be used for both general problem solving and in the management of change. Used in situations whereby the actual problem to be addressed cannot be agreed upon but the decision makers will arrive at accommodations over what kind of changes are to be made.
SCRUM
A presentation of AGILE - A lightweight framework designed to help small close-knit teams of people to develop complex products.
multi method (Multi methodology)
To utilise more than one methodology or part thereof, from different paradigms, within a single invention.
agile
Like MV3 whereby the focus of analysis and design is on the needs of users, but the user group is expected to consist of specialist IS developers.
dependability
A quality of being able to be counted on or relied upon (it can be considered in terms of reliability, availability, safety, security and maintainability).
reliability
The probability over a given time that a system will continue to function correctly as required by the user. Trustworthy and consistently performing well.
availability
The probability that at any given time the system will be functioning correctly or able to be used as intended.
safety
A judgement of how likely the system will cause damage to people, property of the environment.
security
A judgement of the resilience of the system to accidents or deliberate attempts to cause malfunction.
maintainability
Maintainability is a measure or a judgement of how easy it is to keep the system in good working order.
redundancy
Additional spare capacity that can be used in the event of failure (or part failure).
