How to draw a Use Case Diagram?

Time needed: 2 minutes

Here’s the complete guide on how to draw a use case diagram for payroll management system.

  • Step 1: Familiarize Use Case Diagram Symbols

    For beginners, you need to familiarize first with use case symbols to be used.

  • Step 2: Determine the system processes

    The next step is to determine the system’s processes. They will be the use cases of your project.

    You may ask the users about the typical activities done in payroll management.

  • Step 3: Analyze the use cases included

    The gathered information from the users needs to be evaluated to know the general use cases.

    From the general use cases, you will see the sub-cases that are included. But, only include the useful processes related to the payroll management system.

  • Step 4: Plot the Use Case Diagram

    To plot the diagram you will need the users, use cases, container (scope), and their indicators (association). You will base the flow of use cases on the evaluated information from the users.

    Your first move is to place the users involved.

    Next, put the container in the plotted diagram to separate the objects (users and system) scope.

    Then place the use cases of the payroll management.

    Finally, you need to map out the association of the use cases to show the interactions between the user/s and the system.


The UML use case diagram represents the methodology used in system development. It helps developers know the possible inputs that the project should process and perform.

Furthermore, you will discover the needed processes and connect them to the other UML Diagrams. The diagram is also applicable in modeling the software’s use cases (processes). It captures the system’s flow from one process to the next.
