Syllabus outcomes

P1.1Describes the nature of information processes and information technology

P1.2Classifies the functions and operations of information processes and information technology

P2.1Identifies the information processes within an information system

P2.2Recognises the interdependence between each of the information processes

P3.1Identifies social and ethical issues

P4.1Describes the historical developments of information systems and relates these to current and emerging technologies

P5.1Selects and ethically uses computer based and non-computer based resources and tools to process information

P6.1Analyses and describes an identified need

P6.2Generates ideas, considers alternatives and develops solutions for a defined need

Students learn to:

1.Understand the problem

(a)Describe some of the reasons for developing a new information system.

(b)Outline the stages of the traditional system development cycle.

(c)Understand a problem—clear problem statement.

(d)Describe a preliminary investigation:

data collection: compare and contrast methods of data collection (interviews, surveys, observation, measurement).

write a requirement report about the needs of the new system.

(e)Carry out a survey and interview to collect data.

(f)Describe and construct a project plan—create a Gantt chart.

2.Making decisions

(a)Make decisions from the data gathered in the preliminary investigation—constraints on the solution.

(b)Describe and write a feasibility study to judge the appropriateness of a solution—economic, technical, schedule and organisational.

(c)Explain a detailed analysis—organisational charts, analysis report, design specifications.

(d)Identify the stages in the development of a new information system—Case study: A1 Designs.

3.Designing solutions

(a)Interpret and construct design tools to describe the information processes:

context diagram: process, data flow, external entity.

data flow diagram (DFD): process, data flow, data store, external entity.

system flowchart: standard flowcharting systems.

(b)Describe the methods of system design using the feasibility study and the analysis report:

external and internal specifications.

information technology: software packages, custom software.

technical specifications.

text data and beta test.

documentation: user documentation.


(a)Describe the implementation of a new information system.

(b)Describe and compare different methods of the conversion from an old system to a new system:

direct conversion.

parallel conversion.

phased conversion.

pilot conversion.

(c)Understand the importance of training participants to use the new system—training specialists, technical support staff.

5.Testing, evaluating and maintaining

(a)Describe the role of maintaining an information system—computer operators.

(b)Explain the importance of testing a solution.

(c)Explain the importance of evaluating a solution.

(d)Identify the stages in the development of a new information system—Case study: A1 Designs.

6.Social and ethical issues

(a)Explain the difference between machine-centred systems and human-centred systems.

(b)Describe the social and ethical issues related to the work environment:

ergonomics: RSI, CTS.

furniture design: desk, chair.

information technology: screen, keyboard, mouse, software design.

environmental factors: lighting, climate, noise.

(c)Describe the social and ethical issues related to the impact of systems on work:

job design, work pressure, information overload.

use of skills: multiskilling, deskilling.

meaningful work.

nature of the workplace.

social relationships
