Many companies deal with the challenge to introduce MBSE. As a consultant for MBSE I often ask my customer about their objectives to apply MBSE techniques. The answers are more or less the same: the systems are getting more complex and at the same time we must decrease costs and time-to-market and increase the quality.

These are good arguments to change development processes and to apply MBSE. However these arguments are not new. I would had heard the same arguments 20 years ago. Today something is different. There is an enormous pressure on the companies that require major changes.

We are at the beginning of a new era characterized by global cooperations, networking, and global markets with customers, users, and competitors from different cultures with completely different mindsets. We develop complex systems with complex development organizations for complex markets.

The methods & tools to develop these systems must follow the systems challenge curve. The curve for the methods & tools is below the system curve. The gap is filled by the intelligence of the engineers (“project heroes”). Of course we are always better than our methods & tools allow. But the gap is getting wider and wider. Many organizations already feel the pain from the gap.

I think there are two fundamental techniques to shorten the gap. Agile methods and Modeling. Agile methods focus on the – often home made – complexity of the organisation to develop a system. Modeling focus on the inherent complexity of the system itself. That’s why I believe that it is important for many companies to introduce MBSE.

    Dear Tim,

    Would you be kind enough to forward the call below for participation in our SURVEY on Model-Based Software Engineering (MBSwE)
    and the use of Auto-Generated Code (AGC) to members of your MBSE Community, Partners and affiliates?

    I am a member of the NASA MBSE Community of Practice at NASA IV&V and my research team is conducting a survey on
    Model Based Software Engineering with Auto-Generated Code. We will appreciate your support on this effor.

    Should you need further information or clarifications on what we are doing, please don’t hesitate to contact me.

    Thank you.

    Call for participation
    Model-Based Software Engineering (MBSwE) and the use of Auto-Generated Code (AGC) for safety-critical applications have become
    more and more popular. Typical areas include aerospace, automotive, nuclear, military, and many others. MBSwE with automated
    code generation is often considered to produce code with fewer bugs and much faster. The current focus towards autonomous
    systems poses new possibilities and challenges for MBSwE and automated code generation.

    We are evaluating experiences in the use of MBSwE/AGC at NASA and other relevant industries. This survey assesses the current
    state-of-the-practice, advantages and disadvantages, V&V practices, and certification issues for safety-critical systems that
    use MBSwE and/or execute code that is generated from models.

    We would appreciate it if you could participate in our online survey before March 31st, 2016.
    The survey is located at https://www.surveymonkey.com/r/mbsweandagc and we estimate that it would take about 30 minutes to complete.
    All responses are anonymous, unless you specifically choose to provide personal information and your email address.
    At completion, we will be happy to send a copy of our report to respondents who provide their email addresses during the survey or
    request the report by sending an e-mail to SurveyMBSwEandAGC@gmail.com.

    Please forward this call for participation to any and all of your colleagues and acquaintances with experience in this topic.

    Thank you in advance for participating in our survey.
