Dear Engineers,

When I write this message, I think I am writing to the best software developers in the world, or to those who are in the process of being one. I write to ask you a favor. I am a UMA PhD student and I study the use of formal and non-formal models in the software industry.

According to 9 investigations, UML is not being used as it should, but the developers use their own models, designed by them or by their companies. However, these investigations have not included professionals like you, so I want to ask you to help me by answering this survey:

If you have a Google account: https://docs.google.com/forms/d/e/1FAIpQLSdG4bhNWfU3vzSKwG-0j8NuGW47_xmSY1ft...

Reply without logging in: https://docs.google.com/forms/d/e/1FAIpQLSeNm99cxIyT65-5qR6ZCZoDNeFONTf_ODWb...

I also ask you to send this survey to other developers that you know and respect.

Please help me, I promise that your contributions will be recognized in the publications that are possible, therefore, as an optional field I have included the name and email. My biggest goal is to unify all non-formal models to create a modeling language that is the heritage of the industry, built by all of us. If you want to know more, you can write to me at ivan.arroyo@uma.es, ivandarioarroyo@gmail.com or arcouml@gmail.com !!THANKS
