2 © UCLES 2011 9713/13/O/N/11 For Examiner's Use Scenario 1 Question 1 East African Media Ltd, based in Nairobi, owns the African Times newspaper. It has built a new printing plant in Mombasa, many kilometres away. The company also has a factory which manufactures the paper used to produce the newspaper. This is situated next to the printing plant. Many of its reporters work in towns such as Nakuru, Naivasha and Kisumu which are far away from the editor’s office in Nairobi. East African Media Ltd uses the latest technology to print the newspaper. In order to print the paper in Mombasa it requires the use of facsimile transmission. The company uses satellite communications to fax a newspaper for printing.

5 © UCLES 2011 9713/13/O/N/11 [Turn over For Examiner's Use Scenario 2 Questions 2 and 3 Teachers at the International School in Paris use both formative and summative assessment. Formative assessment is the use of test results by the teacher to inform the students of their progress. Summative assessment is the use of the final test result by the teacher to indicate the students’ level of achievement. The teachers use ICT to carry out testing of students. The teachers like to stay in touch with other international schools and they do this using video conferencing because these schools are very far away. They often share documents such as schemes of work and lesson plans.

It currently has personal and payroll details of all its staff. On the new system human resources staff will need to be able to access records quickly. The payroll system will run using all the data on a weekly basis. The master payroll file is sorted in worker number order.

14 © UCLES 2011 9713/13/O/N/11 For Examiner's Use Scenario 4 Questions 6 and 7 Alexandria Bank has changed its banking operations and most of its customers now use its online banking facility. In this system customers are asked to type in three characters from their password in order to gain access to their accounts. When the bank created its online banking system, it employed a number of website developers. Each of the website developers was responsible for a particular aspect of the website. A manager, Wissam, became responsible for coordinating the project and used time management software.

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 October/November 2011 question papers for most IGCSE, GCE Advanced Level and Advanced Subsidiary Level syllabuses and some Ordinary Level syllabuses.

Advantage – One from: If there is a problem with the new system still have the old system as a backup unlike direct changeover Workers can be trained gradually unlike direct changeover Phased implementation – involves implementing one part of the new system whilst other parts continue using old system Advantage – One from: Cheaper than parallel running as you don’t employ two complete sets of workers If there is a problem with the new system still have bulk of old system to fall back on unlike direct changeover. Workers can be trained gradually unlike direct changeover Pilot running – involves running new system in one branch of the organisation whilst old system still operates in other branches Advantage – One from: Cheaper than parallel running as you don’t employ two complete sets of workers (if not mentioned before) If there is a problem with the new system it only affects one branch unlike other methods Other branches can learn from the mistakes made in first branch to have the new system unlike other methods Direct changeover – involves replacing the old system with the new system all in one go. Advantage – One from: Cheaper than parallel running as you don’t have to employ two sets of workers (if not mentioned before) Quicker as there is no delay waiting for bugs to be fixed unlike other methods benefits of the new system become apparent immediately unlike other methods [8] (d) Four from: Compare actual test results with expected results Discuss with managers how successful the new system has been in meeting the original objectives/requirements specification. Get information about how easy the system is to use (questionnaires/interviews) See if the users have accepted/are happy to work with new system (observation) Observe how long it takes to complete a certain task Record any extensions to the system that users have said they would like [4]
