A spaghetti diagram is a quick and easy tool used to trace the path of an item, activity, or person through a process. It helps identify wasteful or unnecessary steps in the workflow and opportunities to improve the process’s effectiveness. Below is an example of a spaghetti diagram of the layout of an admin office. It maps how members of staff move around the office. This simple data, captured quickly on just one working day, helped to redesign the office to save time, make the workplace safer and staff feel less frustrated.
