  12. Can you suggest another common characteristics of organisations?

  13. A complex but standardised method of operating.They are systematic, orThey have systems, or perhaps They are a system!

  22. Data, Information and Knowledge

  23. Knowledge Information Data

  24. Knowledge Information Your speedometer shows you are driving at 90kph. Data

  25. Knowledge You are driving at 90kph, and You are in a 50kph speed zone. Information Your speedometer shows you are driving at 90kph. Data

  26. You know you should slow down, because you are exceeding the speed limit by 40kph, with a probability that you will be caught and fined $230 and lose 6 points off your licence Knowledge You are driving at 90kph, and You are in a 50kph speed zone. Information Data Your speedometer shows you are driving at 90kph.

  27. Data • Gives us one or more pieces of data • By themselves, do not tell us anything particularly useful. • Examples: • Invoice 12345 is for $9,000 • ISYS2006 is a course code • The salary is $40,000

  28. Information • Two or more bits of related data • Where the relationship tells us more than the sum of the parts • Or it has been summarised or filtered in some process • Examples • Invoice 12345 is from IBM, for 3 new computers and the total is $9,000 • The average starting salary at Accenture for an IS graduate is $40,000 • There were 100 IS graduates from Sydney University in 2003

  29. Knowledge • Two or more pieces of information • That have been obtained from unrelated sources • And related using judgement or experience • Giving a new insight or understanding • That may have a degree of uncertainty • That could guide decisions or actions

  30. The definition of an Information System and its use within an organisation

  31. What is an Information System? • An information system (IS) is a pre-established set of inter-related components that collect, process, store, and distribute information, to support decision making and control in an organisation.Laudon & Laudon • Our primary interest in this course is on computer-based IS. • An IS is almost always a component in a broader system.
