A hotel management system use case diagram is used to describe the behavior of the hotel management system. It shows the relationships between users and how they interact with the system.
Moreover, the hotel management system use cases include the project functions using use cases, actors, and their connections. This explains the complex functions of a system.

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.
Hotel Management System Use Case Diagram
The use case diagram example has two main illustrations. These illustrations describe the system’s general and specific processes using include and extend.
Hotel Management System General Use Case
The general use case diagram for hotel management systems shows the main functions of the system. It is a high-level basis for specific use cases.
The general use case is the most common application of a use case diagram. The use case diagrams show the main parts of the system and how information moves between them.
Include and Extend in Use Case Diagram
The terms “include” and “extend” are used to describe the following diagrams. Include explains that sub-use cases are part of a process, whereas extend is the opposite.
Manage Customers Use Case Diagram
This process shows where the admin requires the customer’s basic information. It serves as the basis for the transaction applied or requested by the customer.
As you can see, the customers’ information should be encoded into the system. The system then monitors its details to validate them and then saves the data.
Manage Hotel Rooms Use Case Diagram
This use case allows the admin to manage the hotel or inn rooms’ information as well as their availability. It enables the management to avoid conflict between customers. It is also to improve the customer service of the hotel.
Monitor Hotel Transaction Records Use case Diagram
This process explains how the admin or users handle the services that they offer to their customers because it is an essential part of the hotel management system.
This transaction information and status were used to determine what type of transaction has been accessed by the customer and to prepare for the request or to achieve the desired service by the customer.

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.
Conclusion
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.

How to read a use case diagram
A use case diagram has 3 main elements: actors (stick figures outside the system), use cases (ovals inside the system boundary), and relationships between them.
- Actor. A role played by a human or external system that interacts with the system.
- Use case. A specific goal the actor accomplishes with the system.
- System boundary. The rectangle around the use cases marks what is inside vs outside.
- Association. Line between an actor and a use case they perform.
Use case relationships
- Include. Dashed arrow with “<<include>>” — one use case ALWAYS calls another (e.g., Login is included in Place Order).
- Extend. Dashed arrow with “<<extend>>” — an optional add-on to a base use case (e.g., Apply Discount extends Place Order).
- Generalization. Solid arrow with hollow triangle — one actor or use case is a specialized form of another.
Common capstone mistakes to avoid
- Too granular. Do not create a use case for each button. Focus on business goals like “Manage Inventory.”
- Missing actors. Every use case must be associated with at least one actor.
- Confusing include vs extend. Include is mandatory; Extend is optional.
- System actors as human. External payment gateways, email servers, etc. are actors too.
- No system boundary. Missing rectangle is a common panel critique.
Where the use case diagram fits in Chapter 3
- Section 3.1 (System Overview) or 3.2 (Functional Requirements).
- List each use case with a brief description in a table alongside the diagram.
- Reference each use case when explaining the workflow in later sections.

Frequently asked questions
What is a use case diagram used for in BSIT capstone?
A use case diagram shows what the system does from the user’s perspective: actors, use cases, and their relationships (include, extend, generalization). It goes in Chapter 3 and communicates the functional requirements of the system.
What tool should I use to draw the use case diagram?
Free options: draw.io (browser-based, saves to Google Drive), Lucidchart free tier, PlantUML (text-based, version-controllable), StarUML (30-day trial then reduced feature set), Visual Paradigm Community Edition. Paid options: Microsoft Visio, Lucidchart pro, Enterprise Architect. For BSIT capstones, draw.io is the most commonly used free tool.
How detailed does the use case diagram need to be for capstone defense?
Panel members expect the diagram to match the actual system implementation. Include every major class/use case/entity relevant to the system. Omit trivial helper classes. Every diagram element should have a clear justification. Aim for 1-2 diagrams that fully cover the system, not many partial ones.
Should I use black-and-white or colored diagrams?
Black-and-white is standard for capstone documentation to match the thesis format. Use color only if it improves clarity (e.g., grouping subsystems). Ensure text is readable at printed size (10pt minimum for labels).
Where does this diagram go in the capstone documentation?
Chapter 3 (System Design and Methodology) typically holds all UML diagrams. Introduce each diagram with a 1-paragraph description explaining what it shows and how to read it. Reference specific elements in the surrounding text so panel members can follow the design rationale.
