2 © UCLES 2011 9713/13/M/J/11 For Examiner's Use Scenario 1 Question 1 Oslo Banking is a large banking organisation which offers a variety of services including loans, mortgages and insurance. The bank is currently undertaking a large advertising campaign. One of the ways it will advertise its services is by using posters. Karl is the manager of a small branch. He thinks the advertising will be more effective using flyers. The bank’s advertising department allows several of its team to work from home, where they produce advertising ideas. The initial designs are usually just hand drawn sketches. Karl would like to see these initial designs so that he can see the stages of development of the ideas. Workers are encouraged to send these using fax machines which have been purchased for them by the company. Because of the cold climate it is essential for these workers to have an efficient central heating system.

13 © UCLES 2011 9713/13/M/J/11 [Turn over For Examiner's Use Scenario 3 Questions 5, 6 Mrs Sharif is the head teacher of a large school. She has recently decided to upgrade the school’s computer system so that all teachers use ICT in their lessons. In addition, the system will enable student records, including test scores, calculated as percentages, to be stored efficiently. She has employed Jasvinder Sidhu to develop the new system. Jasvinder will examine all the existing documents which are used with the current student record system. He will need to interview Mrs Sharif as well as examine the way the current system works. He will then design the new system before developing it. After the new system has been created it will need to be tested. When the system has been implemented, Jasvinder will need to produce some program documentation.

UNIVERSITY OF CAMBRIDGE INTERNATIONAL EXAMINATIONS GCE Advanced Subsidiary Level and GCE Advanced Level MARK SCHEME for the May/June 2011 question paper for the guidance of teachers 9713 APPLIED ICT 9713/13 Paper 1 (Written A), maximum raw mark 80 This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the examination. It shows the basis on which Examiners were instructed to award marks. It does not indicate the details of the discussions that took place at an Examiners’ meeting before marking began, which would have considered the acceptability of alternative answers. Mark schemes must be read in conjunction with the question papers and the report on the examination. • Cambridge will not enter into discussions or correspondence in connection with these mark schemes. Cambridge is publishing the mark schemes for the May/June 2011 question papers for most IGCSE, GCE Advanced Level and Advanced Subsidiary Level syllabuses and some Ordinary Level syllabuses.

The format of the input and output can be determined… Each part of the system needs to be examined to see what specific inputs, outputs and processing are required For example: the input would be the details of the students the processing would be the calculation of the test scores/percentages the output would be lists of students and their test scores.
