PragmaDev to Present the Results of Its On-Line Survey on Software Modeling Technologies and Their Usage

Share Article

PragmaDev survey showed that while UML is the most used modeling technology today, it is also intended to decrease by 17% in the coming year. The third most popular modeling technology Matlab is also intended to decrease by 15% so that among the top three modeling technology, SDL is the only one with an intended increase.

2011 modeling technologies and habits survey
This on-line survey took place in February 2011 and gathered 160 participants, most of them out of our existing contacts. The raw results of our survey on modelling technologies can be found here, and the following information is a summary of the survey. Feel free to use this information as long as you quote it is coming from PragmaDev.

Modeling technologies
The top three modeling technologies are UML, SDL, and Matlab. Even though UML is the first modeling technology to be quoted, it is also interesting to state that most of the respondants do not know if they are using a profile or not.

Modeling usage
Modeling technologies are mostly used for documentation but the answers also show a strong usage of models for simulation, verification, code generation, and test. We believe it was difficult for the respondants to distinguish between the different answers such as We do simulation or We do model checking, and We generate skeletons or We generate all the code. So we applied a filter in order to feel the kind of usage for each of the top three modeling technology, and this is what came out:

  • UML users mostly do documentation (56%),
  • Matlab users mostly do simulation (57%),
  • SDL users mostly do code generation (40%).

Upcoming technologies
This is probably one of the most interesting result we get out of this survey, and that gives an idea of the current trends on the modeling market. The key trends are:

  • UML is decreasing by 17%,
  • Matlab is decreasing by 15%,
  • SART is increasing by 121% (but the number of respondants is very small),
  • SysML is increasing by 86%,
  • AADL is increasing by 52%.

Upcoming hot topics
Last question of the survey was about which topic will get the focus in the coming year. Top three answers are:

  • System modeling,
  • Software modeling,
  • Testing.
