PragmaDev Expects UML Modeling Usage to Decrease Again

PragmaDev UML modeling survey

PragmaDev released the results of their recent UML survey. According to their research, UML modeling technology usage is expected to decrease for the third year in a row. However, the effective usage of UML has been slightly growing from 65% in 2011, to 70% in 2012, up to 71% this year. These two trends mostly indicate UML has reached peaked and is about to start its decline.

The top three modeling technologies are UML, Matlab, and SDL (equal with SysML). UML is the first modeling technology to be quoted, and the SDL share is decreasing a bit compared to previous years probably due to the fact that respondent profile has changed. Out of the 13 diagrams in UML, the top 4 are: class diagram, sequence diagram, state chart, and use case diagram.

The usage of each modeling technology confirms UML is mostly used for documentation, SysML, SDL, and Matlab models are used for simulation.
