How to Make a Flowchart: Symbols, Types, Steps, and Templates

When a process has too many steps, decisions, or handoffs, it becomes harder to explain and even harder to improve. A flowchart helps you lay everything out visually, so you can spot gaps, simplify confusing paths, and make the process easier for others to follow.

The good news is that learning how to make a flowchart is fairly straightforward once you know which symbols to use and how to connect them.

In this guide, we’ll walk through how to create a flowchart step by step, choose the right symbols, pick the right type for your process, and use examples and templates to build one faster. 

Need a visual guide to begin with? Here’s a short video with a step-by-step tutorial on how to create a flowchart on IdeaBoard.

Flowchart symbols you need to know before you start

You only need a few standard flowchart symbols to get started.

For most process flowcharts, these symbols are enough. Keep each shape’s meaning consistent throughout the diagram and use arrows to make the sequence easy to follow.

How to make a flowchart step by step

A clear flowchart starts with understanding how the process actually works. Get the scope, sequence, decisions, and handoffs right first. Then translate that logic into a visual structure that is easy to follow and update.

A flowchart software like MockFlow IdeaBoard can be useful throughout this process, especially when multiple people need to map, review, and refine the same workflow together.

You can get started in several ways:

1. Use a ready-made flowchart template to structure the diagram quickly.
2. Start with a blank canvas and build the flowchart from scratch.
3. Generate a flowchart with AI by describing the process, steps, decisions, and outcomes you want to visualize.

Here are the steps to follow:

Step 1: Define the process you want to map

Start with one specific process or workflow.

Clarify:

1. Where the process begins
2. Where it should end
3. Which actions belong in the flow
4. Which decisions change the path
5. Who is involved at different stages

A focused scope keeps the flowchart readable and prevents unrelated workflows from getting pulled into the same diagram. 

Deloitte's 2025 Global Human Capital Trends research found that respondents spend 41% of their daily time on work that does not contribute to organizational value. Mapping the process carefully can make unnecessary steps, repeated handoffs, and low-value activities easier to spot before they are carried forward. 

Step 2: Capture the process steps

In your flowchart software, open a canvas and list the process in the order it happens. Include the main actions first, then add important decisions, exceptions, and handoffs.

For example:

1. Customer submits a request
2. Request is reviewed
3. Approval decision is made
4. Customer is notified
5. Approved request moves to fulfillment

If the process already exists in a document, meeting notes, or another source, there is no need to reconstruct everything manually. IdeaBoard’s Mida AI can turn prompts, documents, or images into structured visual boards that can include flowcharts. This gives teams a useful starting point that can then be reviewed and corrected.

Step 3: Choose the right flowchart structure

Match the structure to what the process needs to communicate.

Use a process flowchart for a straightforward sequence. Choose a swimlane flowchart when ownership changes between teams. A decision flowchart works better when conditions create several possible paths.

Choosing the right format early makes the diagram easier to expand without having to reorganize it later.

Step 4: Apply the correct flowchart symbols

Turn each step into the appropriate flowchart shape.

Use rectangles for actions and diamonds for decisions. Mark clear start and end points, then add input or output symbols where information enters or leaves the process.

Keep labels brief and action-focused. “Review request” communicates more quickly than a full sentence explaining the same action.

Step 5: Connect each step and decision

Use arrows and connectors to make the direction of the process obvious.

Keep the main flow moving consistently from top to bottom or left to right. When a decision creates different outcomes, label each path clearly with terms such as “Approved” and “Rejected.”

If connectors begin crossing frequently, reconsider the layout before adding more detail. A reader should be able to trace any path without stopping to work out where it goes.

Step 6: Refine the flowchart on the canvas

Once the basic flow is mapped, improve the layout and fill any gaps.

Keep related steps close together. Give decision branches enough room to remain readable. Use visual styling only when it helps distinguish stages, responsibilities, or outcomes.

IdeaBoard can also support AI-assisted creation directly on the shared canvas. Its AI Prompt Box can be configured to generate outputs such as flowcharts and swimlane diagrams, while ready-made AI recipes include workflows for decision flowcharts and approval processes.

Teams that want flowcharts closer to the tools they already use can also explore IdeaBoard integrations with tools like Claude, Trello, VS Code, etc. rather than treating the diagram as an isolated file.

Step 7: Review the flow with the people involved

Trace every possible path from start to finish and check whether the diagram reflects the real process.

Look for:

1. Missing actions
2. Decisions that lead nowhere
3. Unclear handoffs
4. Duplicate steps
5. Unaccounted exceptions
6. Labels that need extra explanation

The people who work with the process should review it before the flowchart is finalized. But it becomes a challenge when the people involved work across locations. Gallup's 2026 hybrid-work data shows that 24% of hybrid employees identify decreased collaboration with their team as a challenge. 

IdeaBoard supports remote collaboration with real-time feedback directly on the board, including voice and video comments, which can help reviewers explain a missing step or provide context without separating the discussion from the diagram.

The final flowchart should make the process easy to understand at a glance while still capturing the decisions and handoffs that matter.

Flowchart types, examples, and templates to get you started

The right flowchart type depends on what you need to show. Some are better for simple sequences, while others help clarify ownership, decisions, or data movement. Here are a few examples that show how different flowchart types work. 

1. Process flowchart

Use a process flowchart when you want to show a sequence of steps from start to finish. It works well for repeatable processes such as approvals, onboarding, order handling, or issue resolution.

For instance, a sales process flow could look like this:

Start → Identify prospect → Qualify lead → Schedule sales call → Prepare proposal → Close deal → End

2. Workflow flowchart

A workflow diagram is useful when you want to show how work moves through a series of tasks. It is especially helpful for spotting delays, unnecessary steps, or unclear handoffs.

For example, an operations workflow might follow:

Receive request → Review request → Assign task → Complete task → Quality check?

1. Yes → Approve completion → Update records → Notify requester → End
2. No → Update records → Notify requester → End

3. Swimlane flowchart

Use a swimlane flowchart when several people or teams are involved in the same process. Each lane represents an owner, making responsibilities and handoffs easy to see.

Example of an employee onboarding swimlane flow:

HR creates record → Hiring manager confirms requirements → IT prepares access → Employee completes documents → HR verifies completion

4. Decision flowchart

A decision flowchart works best when the process depends on conditions or choices. Decision symbols create branches such as “Yes” or “No,” making it useful for troubleshooting, qualification, or approval flows.

Here’s an example flow for a support request:

Start → Review support request → Can the issue be resolved immediately?

1. Yes → Resolve issue → Notify customer → End
2. No → Escalate request → Specialist reviews issue → Resolve → End

5. Data flowchart

Use a data flowchart when the focus is on how information moves between users, systems, or processes. It helps clarify where data comes from, where it goes, and how it is handled along the way.

For an online order, the flow could look like:

Customer submits order → Order system receives details → Payment processor confirms payment → Fulfillment system receives order → Customer gets confirmation

FAQs

1. How detailed should a flowchart be?

A flowchart should include enough detail to understand the process without making the diagram difficult to scan. If one part requires many additional steps or branches, create a separate subprocess flowchart for it.

2. Do flowchart decisions always have to be Yes or No?

No. A decision can have several outcomes as long as every branch is clearly labeled and covers the possible results. Yes/No works well for simple decisions, while more complex processes may need labels such as “Approved,” “Needs revision,” or “Rejected.”

3. How do you make a flowchart with IdeaBoard?

To make a flowchart with IdeaBoard, start by outlining the process steps and identifying any decisions or possible outcomes. Add each step to the board, connect the elements in the correct order, and label decision branches clearly. Use the board’s collaborative features to review the flowchart with your team, refine the logic, and keep the final version easy to update.

4. Can AI generate a flowchart from text?

Yes. AI flowchart maker tools can turn a written process, prompt, or document into an initial visual structure with steps, decisions, and connectors. The generated flowchart should still be reviewed to confirm that the logic matches the actual process.

5. What is the difference between a flowchart and a process map?

A flowchart focuses on the sequence of actions and decisions within a process. A process map usually provides broader context, such as responsibilities, inputs, outputs, and how different parts of the process interact.

6. How do you keep a flowchart up to date?

Update the flowchart whenever the underlying process, responsibilities, systems, or decision rules change. Keeping it in an editable shared workspace also makes ongoing reviews and revisions easier.
