A fishbone-structured diagram for a process, used as a brainstorming tool to help understand or improve the process. The main bone represents the process (e.g., interviewer training), and bones coming off of the main bone are pre-identified factors (e.g., training materials) that may affect the quality of the process. From there, potential causes (i.e., lack of resources and time) and effects (i.e., poor quality materials) can be discussed and solutions identified. Also known as a ‘fishbone’ or ‘Ishikawa’ diagram.
