How to use this tool

Walk through step by step, click Start Process to begin the workflow from the beginning, then use Next Step to advance. When a decision gateway is reached, choose the appropriate branch before continuing.

Jump directly to any step, click any task, gateway, or event in the diagram to navigate there instantly: no need to start from the beginning. The SOP panel updates immediately and Back / Next work from that position.

Read the SOP card, the right-hand panel shows the current task's standard operating procedure, owner, inputs, and outputs.

Print or reference, use Print SOP to print the active step, or switch to Reference mode for a filterable index of all SOPs.

Search, the toolbar search bar finds any task or SOP keyword instantly and jumps to that step.
