Maturity of Software Modelling and Model Driven Engineering: a Survey in the Italian Industry

Background: The main claimed advantage of Model-driven engineering is improvement in productivity. However, few information is available about its actual adoption during software development and maintenance in the industry. Objective: The main aim of this work is investigating the level of maturity in the adoption of software models and of Model-driven engineering in the Italian industry. The perspective is that of software engineering researchers. Method: First, we conducted an exploratory personal opinion survey with 155 Italian software professionals. The data were collected with the help of a web-based on-line questionnaire. Then, we conducted focused interviews with three software professionals to interpret doubtful results. Results: Software modelling is a very relevant phenomenon in the Italian industry. Model-Driven techniques are used in the industry, even if (i) only for a limited extent, (ii) despite a quite generalized dissatisfaction about available tools and (iii) despite a generally low experience of the IT personnel in such techniques. Limitations: Generalization of results is limited due to the sample size. Moreover, possible self-exclusion from participants not interested in modelling could have biased the results. Conclusion: Results reinforce existing evidence regarding the usage of software modelling and (partially of) Model-driven engineering in the industry but highlight several aspects of immaturity of the Italian industry.
