June 2010 - Exam Question Paper 11 Damon Tauroa-Rauhihi

Scenario 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.

Question 6a. Other than observation, describe the methods that the systems analyst could use to research the current systems. [3]

Answer 6a. Distribute/Hand out written questionnaires to system users (to complete) Interview current system users face to face Examining documents used in the current system

Question 6b. Describe 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. [8]

Examiner Report Candidates generally struggled with this question. (a) There seemed to be a lack of knowledge regarding this topic. A number of candidates were unable to answer the question preferring instead to assume the Analysis section had been completed and wrote about design instead. (b) Candidates were not able to score well on this part of the question, which asked for validation checks regarding a 12 digit candidate ID number, giving generalised answers without going into detail regarding the ID number.

Question 7a. Explain the purpose of technical documentation. [2]

Answer 7a. Two from: Produced specifically for systems analysts/programmers. Helps when the system needs further development/upgrading/improvements. Helpful should any errors occur in the system and system needs amending to get rid of these errors.

Question 7b. Describe the two types of technical documentation including details of the contents of each one. [8]

Answer 7b. Eight from: Systems documentation ....provides a detailed overview of the whole system. Test data/test plans so that systems analyst can see the results of these/test results. Can use this data again to check if errors have been successfully removed. The results of the systems analysis/DFD diagrams. What is expected of the system/purpose of the system. Overall design decisions such as the choice of hardware and software/file, input and output structures. Systems flowcharts. Program documentation ....produced for program code that has been written. Description of the software/purpose of the software. Reasons for choosing those pieces of existing software that were used instead of the programmer having to write code. Input and output data formats. Program flowcharts/algorithms. Program listing – this will be a complete copy of the code used and annotation explaining what each module of code does. Notes that will help any future programmer to make modifications to the system.

Question 7c. After the system has been developed it will be evaluated. Describe how test results are recorded and explain how they affect this evaluation. [3]

Answer 7c. Three from: (A table) showing the type of test, test data, expected results, actual results and a comment on the results. (One mark for three column headings, two marks for 5 column headings.) Test results will help the systems analyst to make judgements. Comparison will be made of the actual results with the expected results. If the results are not as expected system will need to refined. Comments in the comparison table contribute to the evaluation.

Examiner Report This question was answered in a variable manner with some quite diverging scores. (a) This part of the question elicited the weakest responses of the whole paper with very few candidates appearing to know what live data is. (b) This part of the question was much better answered with marks being gained by most candidates. Quite a number of candidates gained marks for describing the methods but failed to extend their scores by comparing the methods. (c) Candidates found this a difficult question to answer. Many just described evaluation without describing the methods an analyst might use to see how easy the system is to use.
