Assembly Computers’ Components Information System for an Industry

 (ACISI)

Scenario:

      The system analysist visited a computer company for developing a new information system for the maintenance department, which help the company in purchasing hardware components, following up the assembly process.

   The following is a summary of the interview with the users and stakeholders, the manager wants to purchase the required components, so he informed the head of the “maintenance department” to prepare the required information.

      The maintenance department distributes the works to four internal units, unit-1, unit-2, unit-3, and unit-4, sequentially are responsible of the following main issues System unit, Motherboard, Accessories, Monitor. Each unit should do its activity and entering data related to it. The operations in the company as follows:

Unit-1 fixes different components of the system unit. Unit -2 check the motherboard and fix its parts. Unit -2 check the motherboard and fix its parts. Unit -3 connects the required accessories with CPU. Unit -4 connects the Monitor with the system unit. Unit -4 connects the Monitor with the system unit.

The maintenance department prepared orders list of components that required assembling the computer (PC). The maintenance department check the system unit, so it needs to check first the monitor connection and the keyboard settings.

  The maintenance department check the system unit, if it’s not work, so you need to check the power supply, as well as the setting of the operating system.

-Answer the following:

A- Create a use case diagram that includes at least the following:

         a.   Four use cases.                                                                  

         b.   Three actors.                                                                       

         c. Relationships between the Actors and Use cases.            

B- Includes at least one of the following two use cases:                         

      a. <<Include>> use cases.

      b. <<Extend>> use cases
