A graph of a series of successive observations of a particular step, procedure, or operation taken at regular intervals of time is a control chart. Control charts are used to monitor a process, track its performance over time, and help identify when the process is out of control or has changed. Pareto diagrams are used to identify the most frequently occurring quality problems or sources of defects, cause-and-effect diagrams are used to identify the root causes of a problem, fishbone diagrams are a type of cause-and-effect diagram, and learning curves show how the time required to complete a task changes as workers gain experience.
