What are Flowcharts?

Flowcharts are diagrams of user flows and tasks in processes. Designers use these versatile tools to visualize the interactions in designs and present easy-to-understand maps of designs to stakeholders. They connect labeled, standardized symbols with lines to show everything users might do in interactive contexts.

“You cannot understand good design if you do not understand people; design is made for people.”

Map out New Designs and Evaluate Existing Ones using Flowcharts

In user experience (UX) design, designers use flowcharts mainly to plot how users move through an interface, such as an app, to achieve their goals (e.g., to purchase clothes online). They describe the relationships between pages/screens and show all interactive possibilities—the starting points, actions required, moments of decision and endpoints—as users encounter and use interfaces. They also aim to account for the various factors that impact users’ interactions (e.g., busy environments). Since flowcharts are highly visual, they’re valuable reference points throughout projects. Flowcharts have a standardized set of:

  • Symbols – e.g., typically, a rectangle represents an app screen or webpage, a line with an arrow represents the direction users move through a user flow, and a diamond represents a decision point where users must choose an option (so, it’s crucial to show all the directions users can go); and

  • Conventions – e.g., you present data from left to right and top to bottom.

As paper or digital deliverables, flowcharts represent interactive sequences at two levels:

  1. User flows – Overviews of the complete process of steps which users might take through a whole app, service or website (e.g., from accessing a webshop’s landing page to confirming purchases).

  2. Task flows – Specific aspects of the above (e.g., just the checkout process).

You can use flowcharts especially effectively to:

  1. Visualize interactions for ideation and exploration – to:

    1. Account for all possible interactions (at the start of the design process, to shape user flows).

    2. Evaluate your design’s efficiency – anytime during or after development: e.g., you can spot a user flow which takes too many steps to complete, or a dead end that will likely confuse users (e.g., if they find an item is out of stock and don’t know what to do next).

  2. Present to stakeholders:

    1. Internal stakeholders can examine flowcharts whenever you need approval/buy-in before you can proceed to prototyping (although time and resource constraints might suggest you just prototype instead).

    2. External stakeholders (e.g., clients) can understand your project’s scale and scope when you use a flowchart to help explain how your UX deliverables will ultimately appear.

Paper flowcharts work best here, as your design team can easily erase and redraw these while bouncing ideas around.

Create Flowcharts that Capture Realistic Experiences and All Possibilities

You can dissect even the most complex processes into concise, attractive flowcharts on paper or choose from an array of software to create digital flowcharts with varying features (e.g., real-time collaboration, drag-and-drop functionality). Popular flowcharting UX tools include LucidChart, Microsoft Visio and OmniGraffle.

To accurately reflect what your users experience via a flowchart, it’s best to define:

  1. Your users and their needs through UX research.

  2. What you want your solution to help users do.

  3. The tasks and subtasks from point of entry to goal completion: From a point of entry (e.g., when a user Googles and finds your site), you can break each task (e.g., purchasing tickets) into 4–8 subtasks (from clicking an app to completing checkout).

  4. Decision points: Discover the critical times users must think about their activities, and how they’ll form impressions of your product/design.

  5. Various paths users can take: Map out task sequences so users can complete actions easily and without wondering how to use your product/design. (In seamless experiences, users shouldn’t have to think about your product/design itself.)

Your best flowcharts will show you empathize with users at each stage corresponding to their customer journey maps.

Wireflows are alternatives to flowcharts. You need wireframing skills to make these. In a wireflow, you connect the wireframes of various pages according to how users will interact with them. So, you’ll have a more realistic-looking, concrete solution to ideate with and spot potential usability problems. However, wireflows tend to be better for showing more simple designs—e.g., websites with few pages—and they can vary in fidelity, or sophistication. Also, in dynamic solutions where users can interact in more complicated workflows, flowcharts may be better due to limitations in space or resources. Plus, there’s a risk of overinvestment (especially earlier on) if your high-fidelity wireflow gets discarded.

Overall, always approach flowcharts with a designer’s eye for visuals. When you diagram tasks thoughtfully for users’ contexts, you can better plan how to help them move as easily as possible from start to finish in each process. Your solutions will therefore more likely resonate with users.
