The 7 Basic tools for Quality Management



 

Cause-and-effect diagram
 (also called Ishikawa or fishbone chart): Identifies many possible causes for an effect or problem and sorts ideas into useful categories.


Check sheet:
 A structured, prepared form for collecting and analyzing data; a generic tool that can be adapted for a wide variety of purposes.


Control charts:
 Graphs used to study how a process changes over time.


Histogram:
 The most commonly used graph for showing frequency distributions, or how often each different value in a set of data occurs.


Pareto chart:
 Shows on a bar graph which factors are more significant.


Scatter diagram
: Graphs pairs of numerical data, one variable on each axis, to look for a relationship.


Stratification
: A technique that separates data gathered from a variety of sources so that patterns can be seen (some lists replace "stratification" with "flowchart" or "run chart"; the latter is within the description of a scatter diagram).
