8.3+Developing+Information+Systems

=//**8.3 Developing Information Systems**//= The **success of a new system depends upon**: This topic introduces students to the **traditional method for developing systems**. Students must engage in project work, both individually and in teams, which **supports this understanding by:** Alternatives to this model are presented in the HSC course. Students may begin their project work at any time during the Preliminary course. A minimum of 40% course time is to be devoted to the integration of content into project work in both the Preliminary and HSC courses. It is also expected that a significant proportion of time will be devoted to integrated practical activities. || ** Outcomes ** //A student:// **P1.1** describes the nature of information processes and information technology **P1.2** classifies the functions and operations of information processes and information technology **P2.1** identifies and describes the information processes within an information system **P2.2** recognises and explains the interdependence between each of the information processes **P3.1** identifies and describes social and ethical issues **P4.1** describes the historical developments of information systems and relates these to current and emerging technologies **P5.1** selects and ethically uses computer based and non-computer based resources and tools to process information **P6.1** analyses and describes an identified need **P6.2** generates ideas, considers alternatives and develops solutions for a defined need **P7.1** recognises, applies and explains management and communication techniques used in individual and team-based project work **P7.2** uses and justifies technology to support individuals and teams ||
 * New information systems are created when **existing systems do not adequately meet the needs of users** of the information system, or when there is **a need that could be met by an information system**.
 * how well the problem is **//understood//**
 * how the system is **//designed//**
 * how it is **//tested//**, **//evaluated//** and **//maintained//** over time.
 * **planning**
 * **designing** and
 * **implementing** a series of discrete information systems.
