Organizations need to be agile in todays dynamic business landscapes. This calls for other software development approaches and tools. What we need is Model Driven Development. The Mendix platform increases business agility through Model Driven Development.

1. Business Agility through
Model Driven Development

2. “It’s not the strongest who survive,
nor the most intelligent, but the
ones most adaptable to change.”
- Charles Darwin

3. Increasingly, the stability of an enterprise
is rooted in its ability to be dynamic, to
move fast and change quickly.
- James McGovern

4. If you want to make enemies,
try to change something.
- Woodrow Wilson

5. Enterprise Systems, I mean. And not just a
little bit, either. Orders of magnitude
wrong. Billions and billions of dollars worth
of wrong. Hang-our-heads-in-shame
wrong. It’s time to stop the madness.
- Tim Bray

6. Software change
 For every 25% increase in complexity in the
tasks to be automated, the complexity of the
software solution itself rises by 100%!
 Complexity slows change
 Version 3 will take a magnitude longer than
version 1
 What the users think they want will change as
soon as they see what we develop.

organizations and software?

21. Summary
 Enterprises need to be agile
 Software becomes too complex to change
 Dynamic enterprises and software can be aligned
by:
– Providing short feedback cycles
– Involving domain experts in software development
– Using a ubiquitous language
 That’s why we need:
– Domain-Specific Languages
– Service-Oriented Business Applications
– Model Execution
