The growth in popularity of OO programming led to many different systems and ideas about how to represent an Object Oriented architecture with diagrams both for documentation and planning of software.
The best predecessor to UML (called OMT) was described by it’s creators as “essentially an extended Entity-Relationship approach”. When UML was finally released as an official specification, the authors of OMT then distinguished UML as “addressing programming applications” while OMT “addresses programming database applications”

In 1989, Biggerstaff and Richter suggested in a paper that less than half of any typical system can be built with reusable software components. To summarize their paper, it was concluded that “the only way to obtain more significant gains in productivity and quality is to raise the level of abstraction of the components”.
