1.5) Work break down:

2. Project manager contracts with the user who demands the system and write a project plan. (three days)
3. Deliver the draft of project plan documentation to writer to rewrite the documentation and rewrite the document. (three days)
4. Then gives documentation of project plan to SW analyzer to do more analysis to verify the SRS document requirements. Then delivers SRS document to writer. (twenty-six days)
5. SW designer gives the SRS document and start to design the diagrams and models that helps the programmer to implement the project. Then delivers the draft design document to writer. (forty-seven days)
6. The two programmers take a partition of the project to start an implementation. (sixty days)
7. Throw the implementation the inner tester make validate the system and delivers his report to writer (sixteen days)
8. After finish the project and throw the implementation phase the outside tester validate the system and write his document then deliver to writer. (sixteen days)
9. The final report is ready now. (nine days)

1.8) Project management approach:

Software Process Model: To solve an actual problems in an industry, software developer or a team of developers must integrate with a development strategy that include the process, methods and tools layer and generic phases. This strategy is often referred to a process model or a software developing paradigm. [] Our project follows the waterfall model. The steps of waterfall model are:  Requirement Definition  System and Software Design  Implementation  Integration and System Testing  Operation and Maintenance Figure (2.1): Waterfall model

Specification

(4) User Requirements Definition: The user requirement for this system is to make the system fast, flexible, less prone to error, reduce expenses and save the time.  Time can be saved by scheduling the exams, if it is available a question bank to store questions for different subjects.  A system can be given a mark by checking the students answers, and give the result as soon as students finish his exam.  A facility to generate a result chart as pre required without manual interface.  The system should have records of students and faculty that can be access to the system which can be used only for the authorized person.  The system should be more secure for management user records and more reliable to work at any conditions.

(4.1)The products and process features:

This system must be designed as user required. So, the complete requirement must be found:  Quick scheduling: The system helps the faculty member to generate an automatic exam instead of using papers. Which save a time for writing, checking and for input marks. Also, student can see the exam when he login as an individual to the system.  Immediate results and solutions: When the student finishes his exam, the system checks her answers and compared with the correct answer. And the system saves the incorrect and correct answers and calculates the mark of correct answers. Then give the total mark. And send a report for student to see where he is fault.  Easy to store and retrieve information: Rather to save the information on a papers or in separate sheets. There are a data base management to store and retrieve the information needed by the administrator or
