2 9713/12/O/N/14 © UCLES 2014 Scenario 1 Questions 1, 2, 3, 4, 5, 6 and 7 White Nile Foods in Cairo manufactures pre-packed meals. • The ingredients of the meals are mixed in a large-scale food mixer. • The mixture is then moved to the production line where individual containers are filled and a lid and label are placed on each container. • The containers are then moved to the refrigeration plant for storage prior to transportation. A systems analyst has been hired to investigate the current system with a view to designing a new computerised system. Part of the design of a new system involves specifying the required hardware and software. At 15 second intervals the current status of the system, including the temperature of the mixture, will be output to a printer. If they go ahead with computerising the process, in order to keep the same number of workers employed, many workers will have to work part-time. The company would like to use ICT to produce advertising materials to publicise its new range of products.

3 9713/12/O/N/14 © UCLES 2014 [Turn over 1 Three methods of researching the current system would be the use of questionnaires, interviews and observations. For each statement below, tick the most appropriate answer. (a) A drawback of using a questionnaire would be: ✓ Responses can be machine readable As the questionnaires would be anonymous, system users might exaggerate their responses Users can take them away and complete them in their own time It is quicker to collate data [1] (b) A drawback of using interviews would be: ✓ System users might not answer honestly and give the answers they think the interviewer wants to hear Questions can be tailored to suit the individual Supplementary questions can be asked It is possible to make sure that all users’ opinions are collected [1] (c) A drawback of using observations would be: ✓ You can see the system first hand The observer will get a good overall view of the process System users might behave differently if they know they are being watched Users do not have to spend time away from work [1]

4 9713/12/O/N/14 © UCLES 2014 2 Tick four ways in which the inputs, outputs and processing in the existing system would be established by the systems analyst. ✓ Identify who the manager is Identify the sources and volume of input data and collection methods Identify the input documents currently in use Determine how much each worker is paid Determine the frequency of the addition and deletion of records Identify the colours used in the company logo Identify the manual and computer procedures necessary to achieve the current output Identify how many workers there are Identify the manufacturer of the packaging Determine the location of the food mixer [4]
