A Guide To User Flow Diagrams

As a product manager, you’re responsible for ensuring that you create a functional product with an intuitive user journey. To help you accomplish this, you can use a user flow diagram to visualize how users interact with your product in each stage. This will allow you to see the way users move through your product and come to a better understanding of the user decision-making process.

User flow diagrams also enable you to streamline navigation, remove pain points, and create a more engaging experience.

In this article, you will learn what a user flow diagram is, the different types of user flows, and how you create and implement them within your team.

What is a user flow diagram?

A user flow diagram is a visual representation of a user’s journey through your product. It shows the sequence of actions that a user takes from their initial interaction all the way through to their end goal.

User flow diagrams are usually used by product managers and UX designers to better understand and improve the user experience. The diagrams help to identify pain points and areas of confusion to make informed decisions about functionality.

3 types of user flow diagrams

According to the NN Group, user flows can be represented in three ways:

Wireflows

Wireflows are a visual representation of the screens in an app, alongside their user interactions. They can vary from very low fidelity (see example below) to high fidelity screens with arrows linking them. Wireflows provide an overview of all the interactions on a screen, where they lead, and any decision points:

Flowcharts

A flowchart is “a diagram of the sequence of movements or actions of people or things involved in a complex system or activity (Oxford Languages).” It shows a user’s journey through an application, including business logic and alternate flows. They can be used to map out flows inside an application, but also to map business processes:

Key components of a flowchart

When creating a flowchart for a product, use the following elements:

Task diagrams

Task diagrams are similar to flow charts, but they represent a single task within a larger path. Because of this, you can think of a task diagram as a subset of a flowchart. A task diagram utilizes the same components as a flowchart.

Benefits of user flow diagrams

User flow diagrams allow you to:

Describe how the user interacts with the product

A user flow diagram shows how the user interacts with the product to achieve a goal. You can use flows to understand existing applications, especially when you want to create a new product or a new feature.

Avoid missing steps or inconsistencies in the process

User flow diagrams help you identify any inconsistencies or dead ends early in the process. By mapping out your user flow (either through a wireflow or through a flowchart), you make sure you don’t have any dead ends.



Gain shared understanding and validation

User flow diagrams are very useful for validating your concepts and aligning stakeholders.

The development team can better understand your concept and determine your interactions on the page. Subject matter experts can review your process and ensure that everything is in the correct order with the right conditions.

Identify pain points

You can also use user flow diagrams to analyze situations and identify pain points and improvement opportunities. At any point in the journey you might notice that users consistently pause over a particular issue, or that they need more assistance to progress forward.

User flow diagram example

Now let’s walk through an example to better understand how you can create a user flow diagram in practice. Say you want to define the user flow for an application that allows friends from different banks to split bills, facilitating a seamless and secure money transfer. The steps would look like:

  1. Define the user persona
  2. Determine the user goal
  3. Set the entry point
  4. Map out the steps the user takes to achieve the goal
  5. Revisit and identify alternate flows
  6. Sketch the wireframes and add arrows for the interactions
  7. Communicate the results

1. Define the user persona

You should conduct user research and base your persona on actual data and pain points.

For this scenario, you’re looking at an individual who frequently shares expenses with friends and wants a convenient way to split bills, even if their friends are at different banks.

2. Determine the user goal

The user’s goal here is to initiate a bill split with a friend from a different bank and transfer the funds securely.

3. Set the entry point

In this case, the entry point would be to open the app. The user would trigger this because they need to split a bill.

4. Map out the steps the user takes to achieve the goal

To achieve the goal, the user will need to navigate through the following:

  • Open the app and navigate to the split bill feature
  • Enter the total amount of the bill to be split
  • Select the option to split with a friend from a different bank
  • Enter the friend’s bank account details, such as bank name, account number, and routing number
  • Verify the entered bank account details for accuracy
  • Confirm the split and initiate the fund transfer
  • Receive a confirmation of the successful transfer

5. Revisit and identify alternate flows

Once you map out the flow, try to come up with any alternative steps that could come into play, such as:

  • Friend verification — After entering the friend’s bank account details, the app could prompt the user to verify the friend’s identity to ensure the accuracy of the information. This verification step can be done through various means, such as sending a verification code to the friend’s registered email or phone number
  • Error handling for incorrect bank details — If the user enters incorrect bank account details for their friend, the app can provide an error message specifying the issue and offer suggestions on how to correct the information. This may involve prompting the user to double-check the account number, routing number, or bank name
  • Request confirmation from a friend — In specific scenarios, the app might send a request to a friend at a different bank, asking them to confirm the bill split. The friend would receive a notification or message with the details of the split and an option to accept or decline the request. This step adds an extra layer of confirmation and consent from the friend before proceeding with the transaction

6. Sketch the wireframes and add arrows for the interactions

To create a wireflow, you want to sketch the wireframes at this stage. After you have all the screens, use arrows to show their interactions.

While a UX designer can provide more detail, here are the screens we could have for this flow:

  • Split bill feature in the app’s main menu
  • Bill split form with an input field for the total amount
  • Friend selection screen with an option to choose a friend at a different bank
  • Bank account details entry screen with fields for bank name, account number, and routing number
  • Verification screen showing the entered bank account details for confirmation
  • Confirmation screen with a success message and transaction details

7. Communicate the results

Once the flow is complete, you can share it with your stakeholders to receive feedback. Try to identify areas of improvement and work to optimize the user experience.

The user flow diagram for this example would look like:

Tools for creating user flow diagrams

There are a variety of tools to help you create user flows. Here are a few that also have free versions:

Final thoughts

User flow diagrams are powerful tools to help you validate concepts and identify pain points. They allow you to fail fast with minimum effort and ensure that you build the right thing for your users.

By using user flow diagrams, you can:

  • Describe how the user interacts with the product
  • Avoid missing steps or inconsistencies in the process
  • Gain shared understanding and validation
  • Identify pain points

You can follow the example included in this article to build out a user flow diagram for your own product.
