Affinity
Diagram ('KJ' diagram)
A diagram that is used as a method of sorting qualitative
data, which usually comes in the form of short phrases or sentences (eg.
'Customers are unhappy with delivery delays'). It is often done with
Post-it Notes, although the original method used 3" x 5" cards. It
is a great method of working as a group to sort out issues and fuzzy
situations. It is also useful for sorting such as customer comments from
surveys. Building an Affinity Diagram is often known
as 'doing a KJ', after its originator, Kawakita Jiro (this is in order of
surname, given name, as in the Japanese tradition).
