Fichas del conjunto (24)
- 1Information Technology (IT)- the technology involved in capturing and manipulating data
- includes the hardware, software, peripherals, communications media and protocols of systems - 2Information Systems (IS)- the united set of business systems designed to achieve a certain purpose. Comprised of IT as well as people, business processes and context.
IS = IT + Organisation + People - 3The Organisational Learning Curve (Gibson & Nolan (1974)) 6 Stages of Growth
- 4The Hierarchy of Data (Ackoff (1981))
- 5IT Investment Pyramid
- 6Value Creation from IS* Managers must understand how information can be used for best interests of organisations
* Managers must recognise how IS integrates across all org functions
* Managers must recognise the rapid pace of tech change so that emerging opportunities are spotted early
* Managers must have a balanced view of the business and IS to anticipate changes in competitive landscape and then to deploy IS resources appropriately to exploit new business opportunities - 7IS Risks ...if given inappropriate management attention, understanding, and/or support* IS fails to support business goals
* IS fails to support organisational systems
* A misalignment between business and organisational strategy - 8Why Information Systems (IS) MatterCapital Management (investment costs)
Foundation of doing business (business survival)
Productivity Level
Strategic opportunity and advantage - 9Business Drivers of IS1. Operational Excellence
2. New products, services, and business models
3. Customer and supplier intimacy
4. Improved decision-making
5. Competitive Advantage
6. Survival - 10The Problem-Solving Approach 4 Step Model
- 11Problem-Solving Approach Integrated Framework for Describing & Analysing Information Systems (IS)
- 12Approaches to Systems AnalysisTraditional Approach

- 15Object-Oriented Approach
- 16Definition of "Connectivity" in relation to ERDshows the connection between the entities

Due Process - 20Strategic Information Systems Planning (SISP) should achieve these 4 goals:1) aligning investment in IS with business goals
2) exploiting IT for competitive advantage
3) directing efficient and effective management of IS resources
4) developing technology policies and architectures - 21Trailing Edge Technologiesolder than 5 years, still viable, older software requires older hardware to run,
hardware is very expensive to maintain, older programs are harder to modify, older data structures are not
easily turned into information, the software development backlog problem - 22Bleeding Edge Technologieslatest innovations (6 months to 2 years old), relatively expensive but has
potential for great cost savings due to productivity improvement, high risk due to its instability, complex- not
properly understood or applied, unavailability - 23Leading Edge Technologiesstable but new 1 - 5 years old, popular amongst major portion of the industry
segment, cost effective, hence cannot lag behind, possesses low risk, availability of experts - 24—
