Ishikawa Diagram Quiz

An Ishikawa diagram, also known as a fishbone diagram, is a visualization tool used to identify and analyze the potential causes of a specific event or problem. Its purpose is to outline the different steps in a process, demonstrate where quality control issues might arise, and determine which resources are required at specific times.

The Ishikawa diagram was created by Kaoru Ishikawa in the 1960s.

Causes are usually grouped into major categories to identify and classify the sources of variation.

An Ishikawa diagram resembles a fish skeleton, with the 'ribs' representing the causes of an event and the final outcome appearing at the head of the skeleton. It visually represents the relationship between causes and outcomes.

The common uses of the Ishikawa diagram are in product design and quality defect prevention to identify potential factors causing an overall effect.

The two main types of control charts are Shewhart individuals control chart and CUSUM (or cumulative sum control chart).

Control charts are used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions by analyzing the presence of data that differs from the conventional trend or deviates from the control limit line.

Control charts are a statistical process control tool used to determine if a manufacturing or business process is in a state of control.

Control charts are also known as Shewhart charts or process-behavior charts.

Distribution-free control charts are designed to monitor process parameters without any knowledge of the underlying process distributions, and they are becoming increasingly popular due to the availability of advanced techniques for monitoring incoming data streaming.
