3 Problem Description & Purpose The problem facing the Computer Science Department is a complex and lengthy manual grading process, which they currently utilize. This process requires professors and TA s to manually process grades, which takes considerable time and adds unnecessary paperwork. The purpose of the Garnet Computer & Information Sciences Grading System is to replace the current inefficient paper process with a fully automated computer grading system. This will create more time for professors to focus on lectures and increase the level of ease with which they can recall student's grades. Statement of Scope The Garnet Computer & Information Sciences Grading Systems (GCISGS) project is intended to replace current manual grading processes with a reliable software grading system. The grading system will aid Professors/Instructors, TA s, and the department chair to administer grades to students. The functionality of the system will allow addition and removal of courses, grades, and grading categories as well as producing statistical data based on current grades. It will also allow users with sufficient access rights to view current grading information. Historical data will not be kept within the system, but professors are given the option of saving current semester data to their computer system. This statement of scope represents the basis for development of the GCISGS project and is subject to revision based on evolution of the system as it is developed. System Benefits The tangible benefits of the system are as follows: Inexpensive to implement reduced operating costs over extended period of time are far greater then software production cost. Reduced operating costs reduces the number of staff needed, and eliminates the use of paper and other consumable goods. Saves time fast learning curve and easy to use. Saves money reduced operating costs and increased work efficiency. Increases work capacity users will be able to get more work done, in a timely manner. The intangible benefits of the system are as follows: Ease of use Easy to understand point and click interface. Better information organization stored in a single database enabling more efficient work. Flexible different access permissions available for different users. Connects across different platforms system can work on, almost any, existing computer system. Puts users in control of their data users can easily add, change and delete data, depending on their permissions. Greater physical and data security password protected secure system, with backup. Boosts morale increases productivity and efficiency. Page 1 of 14
