About this talk

§  Goal of the study: ●  An EXPLORATORY study●  to understand and characterize ●  the state of the practice ●  in software modeling and MDE practices ●  in the embedded software industry ●  and to identify to what degree, why and how software modeling is

used in this domain.§  We conducted an online opinion survey in 2015§  A paper is sent to a journal and is under review

§  A joint work with:●  Onur Demirors, İzmir Institute of Technology, Turkey●  Deniz Akdur, ASELSAN, A.S., Turkey

§  Motivation:●  Deniz is working in ASELSAN which develops HW/SW (embedded

software) for the defense industry

Background: MBE versus MDE, MDA and MDDModel-Driven Development (MDD)

...treats models as the primary artifact of the development process. Usually, in MDD, code is automatically generated from models.

Model-driven engineering (MDE)

...encompasses all the other tasks of the software engineering (SE) process such as testing and maintenance, and thus, MDE is considered a superset of MDD.

Model-Based Engineering (MBE)

... is a process, in which software models still play an important role although they are not necessarily the key artifacts of the development.

Model-Driven Architecture (MDA)

MDA is the OMG’s particular vision of MDD and thus relies on the use of OMG standards.

Research questions and research method§  We used the Goal, Question, Metric (GQM) methodology, which is

popular in empirical software engineering§  Based on the study’s goal, we raised the following research questions

(RQs):●  RQ1: What is the current state of modeling in the embedded software industry?●  RQ2: What is the current state of MDE and its adoption in the embedded

software industry? ●  And few other RQs

§  We designed the survey with 27 questions:
