Feasibility Study.

Extracts from this document...


Feasibility Study Technical Feasibility: It is technically possible to design a script remarking system because computers can be used to sort, search and update data input using a database management system such as Microsoft Access. The current hardware of the United Kingdom Awarding Body is sufficient, as all they will need to run the system is a computer (preferably with 64Mb RAM, 10Gb hard disk drive, 3.5"/1.4Mb floppy disk drive and a 8Mb or higher graphics card), a standard keyboard and mouse, a printer and a visual display unit to run the system effectively and efficiently. Economic Feasibility: It is economically feasible to design and use this script remarking system because fewer people would need to be employed to do the work of remarking a script and producing the reports manually and more work can be done in a shorter time span, therefore also saving on overheads such as light and heating as well as employee wages, Legal Feasibility: It is legally feasible to use this script remarking system because all the data used will be used for the specific purpose of remarking the candidate's script and nothing else. The data will not be kept longer than necessary and at the candidate's request; the data may be destroyed after a certain period of time. The data is also secure as both administrators and clerical staff need to have their group name and passwords to log into the system successfully, but also the system database password, without both of these, the data cannot be accessed. ...read more.


Clerical staff using the remark system will need to input the data required via forms using a keyboard and (or) a mouse. This will automatically update the queries in place, which will update the reports. The reports will then be outputted using a printer.

Buttons were fixed and a simple yet attractive colour scheme was chosen for the interface. Also there was difficulty in producing a suitable formula to calculate the original grades from the original marks and the re-mark mark and the re-mark grades. After consultation with a tutor, a solution was found and the following formula was devised: IIF(Expression), True, False. Afterwards, the grading formula was designed and is as follows: Grades:IIf([Original_Mark]>=[A],"A",IIf([Original_Mark]>=[B],"B",IIf([Original_Mark]>=[C],"C",IIf([Original_Mark]>=[D],"D",IIf([Original_Mark]>=[E],"E","U"))))). A re-mark grading formula was also considered and implemented and is as follows: Remark_Grade: IIf([Re-mark_Mark]>=[A],"A",IIf([Re-mark_Mark]>=[B],"B",IIf([Re-mark_Mark]>=[C],"C",IIf([Re-mark_Mark]>=[D],"D",IIf([Re-mark_Mark]>=[E],"E","U"))))). Effectiveness: The system re-grades papers and produces reports on the papers that are re-graded when candidate information is inputted via the candidate information input form. Usability: The system is easy for the users to use the interface, it has buttons which open files and forms and have a simplistic design and are attractive to use. Maintainability: The system will be easy to maintain because of its simplicity and will be easy to manipulate to accommodate new requests for different types of information without changing how the system runs excessively. Maintenance Perfective maintenance: For the perfective maintenance, the admin staff can change the queries that create the reports to get the desired results. I.e. changing a query so that the 'Scripts requested by a selected centre' report shows a different centre. Adaptive maintenance: For the adaptive maintenance, staff could use new hardware to help reduce clerical errors. Staff could use OCR and MCR scanners to read the scripts information instead of inputting them manually and therefore reducing human errors. 1 ...read more.
