CONCEPTS/SKILLS
To identify at least 5 information system problems with regards to recording, storing
and retrieval of organisational information at an organisation
To gather data about the organisation system
To design an interface for the new system
To program a computerised system
To test the system
Demonstrate how the the system works
Dimensions/Criteria to be assessed
Describing the problem at the organisation
Producing clear interfaces
Using a programming language of choice to program a system
Demonstrating the system
Objectives to be assessed
To identify 5 information system problems at an organisation
To design an interface that is user friendly to solve the problem
To program a system with the designed interface
To demonstrate the programmed system of its functionality
CALA CONTEXT
It has been observed that most organisations do not have competent and modern information systems to use
when recording, storing and retrieval of organisational information. The teacher has decided that learners use a
programming language of choice and database software to make a system that can be used in such organisations

Background
It has been observed that most learners’ programmers do not have accurate skills to identify real world
problems and design the correct system for an identified problem in school computer labs.
The teacher has decided to let the learners to identify problems in organisations and design real world
systems to solve such problems using programming language of choice.
The learner is required to identify problem from an organisation of choice and come up with a computerised
or automated solution using programming language.
CALA TIP
Show innovation and creativity in the designing of interface and coding the system using programming
language of choice addressing the problem identified.
