The arrow diagramming method is a way of making a plan to accomplish something. It starts by writing down a goal and then breaking it into smaller steps. For each of the smaller steps, you draw an arrow from the step before it to the next step. This helps show the different parts of the plan and how they go together. The arrows help you see which steps need to happen first, which come next and which come last. By working through the steps one at a time, it's easier to remember the whole plan and get it done.
