What Is a System Flowchart?
A system flowchart is a visual representation of how data moves through a system, showing the steps, decisions, and outcomes involved in a process. It helps to break down complex systems into clear, easy-to-follow diagrams, making it easier to understand, analyze, and improve them.
Think of a system flowchart as a roadmap that shows how information flows from one point to another—whether in a business, a computer system, or a manufacturing process. System flowchart is one of the widely known types of flowcharts that is used to illustrate the connections between different parts of a system, including inputs (such as user actions or data entry), processes (where the system does something with the data), and outputs (such as a report, an approval, or a completed action).
Unlike general flowcharts that focus on basic step-by-step tasks, system flowcharts go deeper, often showing:
- How data is processed and stored (e.g., files, databases)
- How different components interact (e.g., user inputs, software operations, external devices)
- The logical flow of information within an entire system
System Flowchart Symbols
System flowcharts use specific symbols to represent different steps in a process. These symbols help break down complex systems into an easy-to-understand visual format. Here are the most commonly used ones:
- Start and end symbol (Oval) – Represents the beginning or end of a system process.
- Process symbol (Rectangle) – Shows an action or step where something happens in the system.
- Input/output symbol (Parallelogram) – Represents data entering or leaving the system, such as user input or displayed results.
- Decision symbol (Diamond) – Indicates a decision point where the process splits based on Yes/No or True/False conditions.
- Connector symbol (Circle or Arrow) – Connects different parts of the system flowchart to maintain a clear and organized flow.
How to Create a System Flowchart
Creating a system flowchart might seem technical, but it’s simply about mapping out how a system works in a clear, visual way. Follow these steps to build one:
Step 1. Define the system process
Start by asking: What process do you want to map? It could be anything from how a company processes orders to how a banking system handles transactions. Clearly defining the process will help you decide what details to include in your system flowchart.
For example, if you’re mapping an online payment system, the process could be:
- A customer enters payment details
- The system verifies the information
- The payment is processed
- A confirmation email is sent
Step 2. Identify inputs and outputs
Inputs are what goes into the system, while outputs are the results produced. Think of them as the starting and ending points of the flowchart.
For an online payment system:
- Inputs: Payment details, customer information
- Outputs: Payment confirmation, receipt email
Clearly identifying these elements helps ensure your system flowchart accurately reflects how data moves through the system.
Step 3. Choose appropriate symbols
System flowcharts use specific symbols to represent different steps. Some key ones include:
- Oval – Start or end of a process
- Rectangle – A process or action step
- Diamond – A decision point (Yes/No, Approved/Rejected)
- Parallelogram – Inputs and outputs (e.g., user input, report generated)
Choosing the right symbols keeps your system flowchart clear and easy to follow.
Step 4. Connect components logically
Now, start linking everything together using arrows to show the flow of information. The connections should be logical and follow the natural order of steps in the process.
For instance, in an order processing system, the arrows might flow like this:
- Customer places an order (input)
- System checks inventory (decision)
- If in stock → Process payment
- If out of stock → Notify customer
- Order is confirmed (output)
Each step should flow naturally to the next without confusion.
Step 5. Review and refine the flowchart
Once your flowchart is complete, take a step back and review it:
- Is the process easy to follow?
- Are the symbols used correctly?
- Are there any missing or unnecessary steps?
Ask someone unfamiliar with the system to look at it. If they can understand it easily, your system flowchart is on the right track!

When to Use System Flowcharts
A system flowchart is useful whenever you need to understand, explain, or improve how a process works. It helps break down complex systems into simple, visual steps. Here are some key situations where a system flowchart is the best tool to use:
1. Designing or improving a process
If you’re creating a new system or updating an existing one, a system flowchart helps you map out the steps and find ways to make it more efficient.
Example: A business improving its online checkout process can use a system flowchart to see where customers might drop off and make changes to simplify the experience.
2. Troubleshooting and fixing issues
When a system isn’t working correctly, a system flowchart can help pinpoint the problem by showing where data flows smoothly and where it gets stuck.
Example: If an ATM isn’t processing withdrawals properly, a system flowchart can help track where the issue occurs—whether in user authentication, account balance checks, or transaction approvals.
3. Explaining how a system works
System flowcharts make it easier to train employees, teach students, or present ideas to teams by providing a clear, step-by-step visual of how a system operates.
Example: A teacher explaining how online banking transactions work can use a system flowchart to show students how money moves from one account to another.
4. Automating tasks and workflows
Before automating a business or software process, you need to understand how each step connects. A system flowchart helps identify repetitive tasks that can be automated.
Example: A company handling customer support can use a flowchart to map out how inquiries are processed and decide where chatbots can handle simple questions automatically.
5. Ensuring compliance and accuracy
Many industries require strict documentation of processes for legal or regulatory reasons. System flowcharts help businesses ensure they follow rules and avoid mistakes.
Example: A healthcare provider can use a system flowchart to track patient data handling, ensuring compliance with privacy laws like HIPAA.

System Flowchart vs Data Flow Diagram
A system flowchart focuses on showing the sequence of steps in a process. It maps out how a system works, highlighting actions, decisions, and the flow of tasks. It’s great for visualizing how a process is carried out step-by-step within a system.
A data flow diagram (DFD), on the other hand, focuses specifically on how data moves within a system. It shows how information enters, is processed, and flows between different parts of the system. DFDs are ideal for understanding how data is handled rather than the tasks being performed.
In short, a system flowchart is about the steps in a process, while a data flow diagram is about how data flows through the system. Both diagrams can complement each other, with system flowcharts providing a process overview and DFDs showing data movement in detail.
System Flowchart vs Program Flowchart
A system flowchart shows the overall process of a system, including all its components and how they interact. It maps out tasks, decisions, inputs, and outputs, providing a high-level view of how the system operates as a whole. It’s used to visualize and improve processes in systems like businesses or organizations.
A program flowchart, on the other hand, is specifically for programming and software development. It focuses on the sequence of operations within a program or algorithm, showing how the program executes step by step. It’s useful for developers to understand the logic of the program, like loops, conditions, and data processing.
In short, a system flowchart represents a complete system’s workflow, while a program flowchart is more focused on how a program or software executes its tasks.
