Cross-factor analysis of software modeling practices versus practitioner demographics in the embedded software industry

Software-intensive embedded systems have evolved to be essential tools of our lives. To cope with growing complexities in embedded software industry, software modeling and model-driven engineering (MDE) have become popular for design, development and testing of these systems. However, the usage of models in embedded software industry and the relevant practices usually vary since challenges, requirements and purposes differ among systems as well as among sectors. To understand the state-of-the-practice of software modeling in embedded systems industry, we designed and conducted a world-wide survey, which accepted 627 responses from 27 different countries. The goal of this paper is to present our work built on this survey to better understand and characterize the cross-factor analysis of software modeling versus practitioner demographics, e.g., degree of using software modeling versus target sectors of the products.
