How to make a process flow diagram in LetDraw

From a blank canvas to a shared process map in a few minutes, right in your browser.

  1. Pick a starting point

    Start blank, or open the Flowchart or User Journey template from the template gallery.

  2. Add lanes

    Draw a frame for each team, role or phase. Frames work as lanes and keep their steps together when you move them.

  3. Add and connect steps

    Drop process and decision shapes from the flowchart library and connect them with arrows that stay attached.

  4. Review and share

    Collect feedback with comments, edit together in real time, or export the process map as PNG, SVG or PDF.

Beyond boxes and arrows

Workflow diagrams and customer journeys in one process diagram tool

  • Customer journey template with phases and satisfaction scores
  • Frames as lanes for teams, roles or phases

What people map

A process map for every team

From a three-step approval to a cross-team operating procedure.

Approval workflows

Show who signs off on what, and where requests go when the answer is no.

Customer journeys

Follow a customer from first visit to support, and mark the moments that feel good or bad.

Cross-team handoffs

Give each team its own lane so handoffs between sales, support and billing are easy to spot.

Standard procedures

Document recurring work once, keep it in a shared workspace and update it as the process changes.

Incident response

Lay out who does what when something breaks, so the next on-call engineer is not guessing.

Process improvement

Draw today's process and the improved one side by side, and use version history to see how it evolved.
