My provocative message at the panel was that: Modeling is dead! In the sense we cannot expect We should move to Un-Modeling Practices, that is: remove modelling as a tool for everybody, using modelling tools as experts, and let people enjoy only the little bit they deserve, without forcing MDD frameworks, which are usually not easily accepted Modeling should be used under the hood and each actor should be shown the proper tool (including programmers, who are not easily buying the model-driven approaches at all) This will not be possible until language and tool designers will be software engineers only (just think at the terrible modelling tools we are able to build). I think all this poses extremely complex challenges to the modelling and software engineering community. It's up to us to keep up with these challenges, or become obsolete (aka. remain a very small niche in the software development world).

1. UN-MODELING
Because modeling is dead.
Marco Brambilla

2. Disclaimers
(coming up also from the discussion with other panelists
Bran Selic, Mark Van Den Brand, and the audience)
Yes, modeling is good
Yes, you can use modeling for communicate
Yes, everyone is “naturally” modeling when
thinking and working
Yes, we must educate people to modeling
And yet…

3. The modelers
Objective of every modeler
Evangelization
Rejoicing with modeling adoptions

4.  17 years of WebML
 IFML standardization @OMG
 30+ years teaching modeling
 A (grown-up) startup
 Plenty of research projects
Our struggle

5. Lessons learned
Just one
Don’t try to educate the “market”

6. Lessons learned
So..
Forget and give up modeling?

7. Lessons learned
Not really, but embrace
UN-MODELING
The practice of using modeling as an expert and let
people enjoy only the little bit they deserve.

8. Example 1: Mobile IFML

9. COMO App creator
 Wizard, component-composer based
 One simple message

10. Example 2: BPM

11. From BPM to PPM

12. Take home message
 Being a modeler is hard
 Harder than in the past
 The challenge is not to show off modeling,
is to hide it

13. BE A MODELER
and up with modeling!
