Key Flowchart Symbols and Their Meanings
Before diving into the steps of creating a flowchart, it’s essential to understand the common symbols used and their respective meanings. These symbols are standardized to ensure consistency and clarity across different flowcharts.
- Oval (Terminator): Represents the start or end of a process.
- Rectangle (Process): Indicates a step or activity in the process.
- Diamond (Decision): Represents a point where a decision needs to be made, usually with a yes/no or true/false outcome.
- Parallelogram (Input/Output): Represents data entering or leaving the process.
- Arrow (Flow Line): Connects symbols and indicates the direction of the process flow.
- Circle (Connector): Used to connect different parts of the flowchart, especially when it spans multiple pages.
- Document: Represents a document or report.
- Data (Database): Represents data stored in a database.
- Delay: Represents a waiting period.
- Off-Page Connector: Similar to a connector but specifically used to connect different pages of a flowchart.
Step-by-Step Guide to Creating a Flowchart
Here’s a comprehensive guide on how to create effective flowcharts, covering everything from initial planning to final review.
Step 1: Define the Process
Before you start drawing symbols and connecting lines, it’s crucial to clearly define the process you want to represent. Ask yourself the following questions:
- What is the purpose of the process? What are you trying to achieve with this process?
- What are the inputs to the process? What data, materials, or resources are required to start the process?
- What are the outputs of the process? What is the final product or result of the process?
- Who are the stakeholders involved? Who is responsible for each step of the process? Who will be affected by the process?
- What are the boundaries of the process? Where does the process start and end?
Clearly defining the process will help you stay focused and ensure that your flowchart accurately reflects the actual workflow.
Example: Let’s say you want to create a flowchart for the “Order Processing” process in an e-commerce business. The purpose is to fulfill customer orders efficiently. The inputs are customer order details, payment information, and product inventory. The outputs are shipped orders and updated inventory records. The stakeholders are the customer, sales team, warehouse staff, and shipping department. The process starts when the customer places an order and ends when the order is delivered.
Step 2: Identify the Steps
Once you’ve defined the process, the next step is to identify all the individual steps involved. Break down the process into smaller, manageable tasks or activities. List these steps in the correct sequence, from the beginning to the end.
Consider using a simple list or outline to organize the steps. This will help you ensure that you don’t miss any important details.
Example: For the “Order Processing” process, the steps might include:
- Customer places order
- System verifies payment
- Inventory is checked
- If inventory is sufficient, proceed to step 5. If not, notify the customer.
- Order is picked and packed
- Shipping label is generated
- Order is shipped
- Customer receives order
- Inventory is updated
Step 3: Choose a Flowchart Tool
There are many different tools available for creating flowcharts, ranging from simple drawing programs to specialized flowchart software. Choose a tool that suits your needs and technical skills.
Here are some popular options:
- Microsoft Visio: A powerful and versatile diagramming tool with a wide range of flowchart templates and symbols. It’s a good option for complex flowcharts and professional use.
- Lucidchart: A web-based diagramming tool that offers real-time collaboration features and a user-friendly interface. It’s a great choice for teams working remotely.
- Draw.io: A free and open-source diagramming tool that can be used online or offline. It’s a simple and straightforward option for basic flowcharts.
- Google Drawings: A free, basic diagramming tool integrated with Google Workspace. It’s suitable for simple flowcharts and collaboration within Google Drive.
- Microsoft Word/PowerPoint: While not dedicated flowchart tools, Word and PowerPoint can be used to create basic flowcharts using their built-in shapes and connectors.
- Miro/Mural: These are collaborative whiteboarding platforms that are also useful for creating flowcharts as part of brainstorming sessions.
Consider the following factors when choosing a flowchart tool:
- Ease of use: How intuitive is the tool? Can you easily create and connect shapes?
- Features: Does the tool offer the symbols and templates you need? Does it support collaboration and version control?
- Cost: Is the tool free or paid? What is the pricing structure?
- Platform: Is the tool web-based, desktop-based, or both?
- Integration: Does the tool integrate with other software you use?
Step 4: Draw the Flowchart
Now it’s time to start drawing the flowchart using your chosen tool. Follow these guidelines to ensure clarity and consistency:
- Start with the Terminator symbol (Oval): Place an oval at the top of the page to represent the start of the process. Label it “Start” or the initial event that triggers the process.
- Add Process symbols (Rectangles): For each step you identified in Step 2, draw a rectangle and write a brief description of the activity inside the rectangle. Position the rectangles in the order in which the steps occur.
- Add Decision symbols (Diamonds): If a step involves a decision, use a diamond shape. Write the question or decision point inside the diamond. Draw two or more flow lines (arrows) emerging from the diamond, each labeled with a possible outcome (e.g., “Yes,” “No,” “True,” “False”).
- Add Input/Output symbols (Parallelograms): If a step involves data entering or leaving the process, use a parallelogram. Label the parallelogram with the type of data being input or output (e.g., “Customer Order,” “Shipping Label”).
- Connect the symbols with Flow Lines (Arrows): Use arrows to connect the symbols and indicate the direction of the process flow. Ensure that the arrows clearly show the sequence of steps.
- Use Connectors (Circles): If the flowchart is large or complex, use connectors to link different parts of the diagram. Label the connectors with the same identifier to indicate that they are connected.
- End with the Terminator symbol (Oval): Place an oval at the bottom of the page to represent the end of the process. Label it “End” or the final outcome of the process.
Example: Here’s how the “Order Processing” flowchart might look:
Start (Oval)
|
V
Customer Places Order (Rectangle)
|
V
System Verifies Payment (Rectangle)
|
V
Inventory Checked (Rectangle)
|
V
Is Inventory Sufficient? (Diamond)
/ \
Yes No
| |
V V
Order Picked and Packed (Rectangle) Notify Customer (Rectangle)
| |
V V
Shipping Label Generated (Rectangle) End (Oval)
|
V
Order Shipped (Rectangle)
|
V
Customer Receives Order (Rectangle)
|
V
Inventory Updated (Rectangle)
|
V
End (Oval)
Step 5: Review and Refine
Once you’ve drawn the initial flowchart, take some time to review and refine it. Ask yourself the following questions:
- Is the flowchart accurate? Does it accurately represent the actual process?
- Is the flowchart complete? Are all the steps and decisions included?
- Is the flowchart clear and easy to understand? Are the symbols and labels clear and concise? Is the flow of the process easy to follow?
- Is the flowchart consistent? Are the symbols and labels used consistently throughout the diagram?
- Are there any areas for improvement? Can the process be simplified or streamlined?
Get feedback from others who are familiar with the process. They may be able to identify errors or suggest improvements that you missed.
Make any necessary revisions to the flowchart based on your review and feedback.
Step 6: Finalize and Share
Once you’re satisfied with the flowchart, finalize it and share it with the relevant stakeholders. Save the flowchart in a suitable format (e.g., PDF, PNG, JPG) and distribute it electronically or print it out.
Consider storing the flowchart in a central location where everyone can access it easily. This will ensure that everyone is working with the same version of the diagram.
Regularly review and update the flowchart as the process changes. This will ensure that the diagram remains accurate and relevant over time.
Tips for Creating Effective Flowcharts
Here are some additional tips to help you create flowcharts that are clear, concise, and effective:
- Use consistent symbols: Stick to the standard flowchart symbols to avoid confusion.
- Keep it simple: Avoid adding unnecessary details or complexity. Focus on the essential steps and decisions.
- Use clear and concise labels: Use short, descriptive labels that accurately describe the activity or decision.
- Maintain a consistent flow direction: Generally, flowcharts flow from top to bottom or left to right. Stick to one direction to avoid confusion.
- Avoid crossing flow lines: If possible, avoid crossing flow lines. If you must cross them, use a small arc to indicate that the lines are not connected.
- Use color strategically: Use color to highlight different aspects of the process, such as different departments or roles. However, avoid using too many colors, as this can make the flowchart difficult to read.
- Test the flowchart: Walk through the flowchart with someone who is not familiar with the process to see if they can understand it.
- Use swimlanes for cross-functional processes: If the process involves multiple departments or roles, use swimlanes to visually separate the steps performed by each group.
- Consider hierarchical flowcharts: For very complex processes, consider using a hierarchical flowchart, where the main flowchart provides an overview and sub-flowcharts provide more detail for specific steps.
- Document assumptions: If you’ve made any assumptions about the process, document them on the flowchart or in a separate document.
Common Flowchart Mistakes to Avoid
Here are some common mistakes to avoid when creating flowcharts:
- Overly complex flowcharts: Trying to include too much detail in a single flowchart can make it confusing and difficult to understand. Break down complex processes into smaller, more manageable flowcharts.
- Inconsistent use of symbols: Using different symbols for the same type of activity or decision can lead to confusion. Stick to the standard flowchart symbols.
- Missing steps or decisions: Failing to include all the necessary steps or decisions can make the flowchart inaccurate and incomplete.
- Unclear or ambiguous labels: Using vague or ambiguous labels can make it difficult to understand the meaning of each step or decision.
- Lack of a clear start and end point: Every flowchart should have a clear start and end point, indicated by the Terminator symbol.
- Ignoring feedback: Failing to get feedback from others and incorporate it into the flowchart can result in a less effective diagram.
- Not updating the flowchart: Processes change over time, so it’s important to regularly review and update the flowchart to ensure that it remains accurate and relevant.
- Using flowcharts for everything: Flowcharts are great, but they are not always the best tool for the job. Consider alternative visualization methods, such as process maps or swimlane diagrams, if they are more appropriate.
