Objectory Systems was a software company based in Sweden that was instrumental in the development of Object-oriented program design. Founded in 1987 by Ivar Jacobson, the company developed Objectory, an object-oriented development method which was an extension of what is known as the Ericsson Approach , a modeling language developed at Ericsson. This language featured state charts with activity diagrams, as well as sequence diagrams.
In 1991, Ericsson purchased a substantial amount of the stake in Objectory Systems. As a result, Objectory Systems became known as Objectory AB— a subsidiary of Ericsson. In 1995, Rational Software Corporation acquired the subsidiary.
