- Unit 1: Describe the basic concepts of information systemsASSESSMENT CRITERIA11
- 1.1The concepts of “systems” and “systems thinking” are explained and the types of systems (e.g., stable, simple, open, closed) are named
- 1.2The common characteristics of systems (e.g., subsystems, system boundaries, redundancy, entropy) are named and illustrated

- 1.9The phases in the systems development life cycle and the deliverables from each phase are described and the roles and responsibilities of the people involved in developing or maintaining systems.
- 1.10The diagrammatic representation of systems (e.g., data flow, diagrams, hierarchical charts) is explained.
- 1.11An individual’s right to privacy and the possible conflicts between these rights and the use of information systems (e.g., unwanted consequences of sharing information (junk mail) are described
- Unit 2: Identify basic issues that determine the way computer-based information systems are implementedASSESSMENT CRITERIA9
- 1.1The opportunities, advantages and risks of using computers in business are discussed.
- 1.2The advantages and disadvantages of purchasing versus developing application software are contrasted
- 1.3The methods, advantages and disadvantages of developing an information system (e.g., end-user computing, in-house development, prototyping, application development tools) are described.
- 1.4The procedures for determining the advantages and disadvantages of using software houses/bureaus to develop information systems (e.g., a request for quotation) are described.
- 1.5The changing role of the user in systems implementation (e.g., from a passive spectator to end-user computing and joint application development sessions) is described.
- 1.6The impact of computer/information technology on society (e.g., ethics, privacy, property rights/intellectual property) is described.
- 1.7The impact of computers/information technology on organisations and the work environments (e.g., change of culture, computer crime, human error and computer malfunction, quality of work life) is described.
- 1.8he impact of computers/information technology on information systems (e.g., increased value of information, risks, controls) is described.
- 1.9The impact of computers/information technology on current legislation (e.g., copyright and privacy laws) is described.
- Unit 3: Participate in conducting feasibility studiesASSESSMENT CRITERIA3
- 1.1The categories of systems feasibility (e.g., technical, economic, operational, schedule, legal) are named.
- 1.2Cost/benefit analyses of information systems are prepared.
- 1.3Using common techniques to make system selection evaluations (e.g., bench-mark tests, volume sizing, systems sizing) are assisted.
- Unit 4: Specify user information systems requirementsASSESSMENT CRITERIA5
- 1.1The functions of, and information required from a system which is to be implemented are specified.
- 1.2The characteristics required of the system which is to be implemented (e.g., availability, maintainability, usability) are suggested.
- 1.3The appropriate person-machine interfaces of the system are specified.
- 1.4The corporate information required for the company’s database which the system must provide is identified.
- 1.5The systems control requirements enabling the system to be audited (e.g., audit trail, levels/types of security) are suggested.
- Unit 5: Contribute to the implementation of information systemsASSESSMENT CRITERIA6
- 1.1Project team contribution in system implementation is conducted in a participative manner
- 1.2End-user computing facilities (associated with an information centre) are utilised to implement systems
- 1.3The types of testing and the goal of each type, which should be concluded before a system is installed is described
- 1.4Appropriate test data and test procedures which should be performed successfully before the user accepts a system are identified
- 1.5The steps in installing information systems, and who is responsible for each step (e.g., hardware acquisition, staff training, site preparation) are named
- 1.6The advantages and disadvantages of the types of systems conversion/methods of changeover (e.g., direct conversion, phased conversion, parallel conversion, pilot conversion) are named
- Unit 6: Conduct post-implementation reviews of information systemsASSESSMENT CRITERIA5
- 1.1Appropriate timeframes to follow different types of post-implementation review procedures (e.g., event-driven reviews, time-driven reviews) are determined
- 1.2The factors which must be considered during a post-implementation review (e.g., link between organization’s mission and the system, system’s performance, implementation costs) are named
- 1.3The actual performance of all system components with their expected performance (e.g., hardware, software, networks, procedures, personnel) are compared
- 1.4The success of the system (e.g., extent to which documented user requirements met) is measured
- 1.5A system’s benefits and costs are determined
- Unit 7: Identify types of system maintenance and describe techniques for maintaining and upgrading systemsASSESSMENT CRITERIA4
- 1.1The causes of changes which may need to be made to installed systems (e.g., new user request, technical enhancements, errors in design) are named
- 1.2The types of maintenance, and when each type is appropriate (e.g., patch, release) are identified and described
- 1.3The relationship between maintenance and design (e.g., good design, less expensive maintenance) is defined
- 1.4The financial implication of maintenance (e.g., increase in system’s age increases maintenance costs) is determined and described
