What happened to model Sylvia Panda of Brazil?

Whatever happened to model-based software engineering?

• System models, software models, data models ... meta-models. Was this a false hope, a niche technology, or one whose time has not yet come? Why didn't model-based software engineering become more successful?  Is it too rigid?  Too complex?  Too abstract to be popular? See also: , since model-based software engineering was in a way the pinnacle of CASE methods in terms of hopes for generality and power.

  Hmm... I've been wondering the same thing. I get that ADD (attention deficit disorder) has become vogue, but I can't help thinking that the value of modeling has been tossed out with the agile movement. It's funny, I've watched some really smart people spend months trying to figure things out without a model, to no avail, not even realizing what's happening. I mentioned that a model could help repeatedly, because the smart folks weren't familiar with the modeling technique they just kept working really hard. Finally, on a Friday afternoon they were exhausted enough to listen. I taught them about an activity diagram in a couple of days. They were able to get the entire job done in a couple of weeks thereafter. I'm curious what other people think, I'm of the opinion that modeling is not used much because the skill has atrofied and previous efforts were long winded self fulfilling activities. Agile is used to short circuit the tendency for analysis paralysis. If it produces assets quickly, as it should, the effort produces incremental results that adapt to changing conditions. Honestly, a good well thought out model provides insights far beyond the short term deliverable. I just built a model with five key people the past few days, it provided a common language and frame of reference that will last for years to come. It took three full days of focus time with very busy people. Even though it wasn't a formal model, it served the same purpose. It seems to me that the reason formal modeling is not used as much as it was is because the activity has been replaced by prototyping. Tools to generate assets are much better than in the past. Modeling was more useful when it took a long time or a lot of money to test a concept or develop it. So, it's a combination of a lot of things, skill, tools attitudes and unfamiliarity.
