May/June 2010 Scenario 4

Questions 6 and 7 Ian Byun PowerPoint Presentation May/June 2010 Scenario 4

Dar Es Salaam High School has recently been formed by joining together six smaller schools. The head teacher wants to have a modern ICT system to administer staff and student records. She has decided to employ a systems analyst to look at the existing systems and recommend a new system. The system will need to produce hundreds of reports in one session and should be able to find individual records very quickly. Using the results of the analysis of the current system the analyst will need to design the new system. Once the system has been designed and developed, user and technical documentation will need to be produced. Scenario

Other than observation describe the methods that the systems analyst could use to research the current systems. Distribute written questionnaires to system users to complete Interview current system users face to face Examining documents used in the current system

The answers provided were generally vague descriptions with little reference to teachers and the school. It is surprising to see that despite teachers being the focal point of this scenario as being the ‘system users’ candidates often referred to ‘workers’ or ‘employees’ thereby implying that everybody would be interviewed or given questionnaires rather than the staff concerned. Some candidates were able to answer the question well. Examiners report

Design four different items that the systems analyst will need to include at the design stage. Using the scenario of Dar Es Salaam High School, explain the factors that will influence the choice of each item.

Candidates were able to score highly on the part of the question which asked for items of design but, despite being told in the question to refer to the scenario, candidates frequently gave general answers not related specifically to the scenario when explaining the factors. Examiners Report

Produced specifically for systems analyst/programmers. Helps when the system needs further development/upgrading or improvements Helpful should any errors occur in the system and system needs amending to get rid of these errors Explain the purpose of technical documentation

This was the part of the question which most candidates found straightforward with many scoring high marks. Examiners Report

Systems documentation Provides a detailed overview of the whole system. Test data/plans so that systems analyst can see the results of these Can use this data again to check if errors have been successfully removed Program documentation Produced for program code that has been written Description of the software/purpose of the software Input and output data formats Program flowcharts/algorithms Describe the two types of technical documentation including details of the contents of each one

Examiners Report This part of the question enabled candidates to score some marks with many getting quite high marks. It was, however, the question which was left unanswered by a substantial number of candidates.

After the system has been developed it will be evaluated. Describe how test results are recorded and explain how they affect this evaluation ,[object Object]

Comparisons will be made of the actual results with the expected results
