Panel 5 of the Tree swing cartoons

A tree swing cartoon or tire swing cartoon is a humorous graphical metaphor that purports to explain communication pitfalls in the division of labor in the development of a product.[1][2] It depicts how different departments implement or describe a tire swing attached to a tree, and how different it is from what the customer actually intended. It has also been used to illustrate the waterfall model of software development.[3]

The original version appears to be from the early 1970s, possibly 1973.[4][5][6] Many variants of it appeared later in several books on education, software engineering and management.[7]
