The Payroll Management System Use Case Diagram is one of the methods used to show the processes involved in payroll system. It depicts the system’s supposed structure and behavior.
Additionally, the diagram consists of processes (use cases) and users or “actors”. It uses defined symbols to describe the overall flow of the system.

What is a Use Case Diagram?
The use case diagram for payroll management system shows the sample behavior of the software. It includes the project functions using use cases, actors, and their connections.
Moreover, the diagram assists you to define and organize project needs. This also provides a clear picture of the user and system relationships. Therefore, this diagram depicts the complex functions of a system including how the user reacts to it.
Importance of UML Use Case Diagram
Helping the developers and businesses with system management is one of the importance of the UML use case diagram. It includes the procedures from the viewpoint of users.
Furthermore, the diagram serves as the system analysis to identify, clarify, and organize the project needs. This diagram works best with other UML Diagrams for Payroll Management System. Other UML diagrams include activity, class, sequence, deployment, and component diagrams.
Payroll Management System Use Case Diagram
The use case diagram example for payroll management system has two main illustrations. These illustrations describe the system’s general and specific processes using include and extend.
Payroll Management System General Use Case Diagram
The general use case diagram shows the main functions of the system. It is based on the transactions done in managing payrolls.
The general use case is the most common application of a use case diagram. The use case diagrams depict the system’s main components as well as the flow of information between them.
Use Case Diagram for Payroll Management System using Include and Extend
The use case diagram using include and extend is used to elaborate the proceeding diagrams. The terms include and extend in the use case diagram are known as indicators.
The label include indicates that the sub-processes of the main processes must be included to complete the task. Extend, on the other hand, declares that the sub-processes can only be performed when needed.
Monitor and Manage Employee Use Case Diagram
This is where the system admin (employer/user) manages their employee’s information and status. In this process, they were able to assign the field of work of their employee and monitor their outputs and workloads.
Monitor and Release Salary Record Use Case Diagram
The illustration of this process includes assigning job departments to the employee, job title, and salary rate. The employee will be informed of his/her function as part of the company or establishment.
Manage Services and Bonuses Use Case Diagram
This process allows the admin to have the salary rates given to their employees. The information is based on the performance of the employees. This function also saves important information and calculates the fair salary for all.
You can add more to this illustration and it is up to you how will you create your diagram. But make sure to have precise information and consider the included use cases.

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.
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 stereotype — one use case ALWAYS calls another (e.g., Login is included in Place Order).
- Extend. Dashed arrow with extend stereotype — 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.
- Missing actors. Every use case must be associated with at least one actor.
- Confusing include vs extend. Include is mandatory; Extend is optional.
- 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.
