Understanding the problem

 ***Highlighted means changes to the 2008 syllabus
 

 Students learn about:

 Students learn to:

  • approaches to identify problems with existing systems, including:
    • interviewing/surveying users of the information system
    • interviewing/surveying participants
    • analysing the existing system by determining:
      • how it works
      • what it does
      • who uses it
  • requirement reports
  • requirement prototype - a working model of an information system, built in order to understand the requirements of the system
    • used when the problem is not easily understood
    • repetitive process of prototype modification and participants feedback until the problem is understood
    • can be the basis for further system development
 

 

  • apply appropriate techniques in understanding the problem
  • interpret a requirements report which includes:
    • the purpose of the systems
    • an analysis of an existing system
    • definition of extra requirements
  • diagrammatically represent existing systems using context diagrams and data flow diagrams
  • identify, communicate with and involve participants of the current system
  • create a requirements prototype from applications packages that provide:
    • screen generators
    • report generators
  • use a prototype to clarify participants understanding of the problem
 
Annotations:
***Minor changes have been made to the original dot points to tighten and clarify definitions of terms and concepts and to remove ambiguities.
***The term requirements prototype is introduced.
