Importance of Use Case Diagram in UML

The purpose of this diagram is to help the developers understand system management. It turns the concept into an illustration that mirrors the overall system function. This also determines the requirements of a system.

Furthermore, the diagram serves as the system analysis to identify, clarify, and organize the project’s needs. It works best with other unified modeling languages (UML) diagrams such as activity, class, sequence, deployment, and component diagrams.

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 hotel 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 hotel management.

  • Step 3: Analyze the use cases included

    To find out what the general use cases are, the information from the users needs to be evaluated.

    From the general use cases, you will see the sub-cases that are included. However, only include the processes that are relevant to the hotel management system. 

  • Step 4: Plot the Use Case Diagram

    To plot the diagram, you will need the users, use cases, containers (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 put in the use cases of the hotel management.

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