SUMMARY:Your Pipeline Is Fast… But Is Your System Right? From Spec-First
  to Simulation-Driven Software Engineering - Marc Hornbeek

DESCRIPTION:DevOps has made pipelines fast\, automated\, and highly reliab
 le. We deploy more frequently than ever before. Yet systems still fail in 
 production\, not because we cannot deliver quickly\, but because we often 
 build the wrong behavior.\n\nSpec-first approaches\, user stories\, and ev
 en modern testing practices validate assumptions too late. By the time gap
 s\, edge cases\, and unintended interactions are discovered\, teams are al
 ready deep into rework\, defect cycles\, and operational risk.\n\nThis tal
 k introduces Simulation-Driven Software Engineering (SDSE) as the next ste
 p beyond spec-first thinking. Instead of relying on static requirements\, 
 SDSE enables teams to create executable behavioral simulations before code
  exists. These simulations model real-world conditions\, including failure
 s\, timing\, and complex interactions across systems.\n\nDrawing on real-w
 orld experience\, this session shows how simulation can expose hidden assu
 mptions early\, align stakeholders on actual system behavior\, and dramati
 cally reduce defects and rework.\n\nThe goal is not to slow down DevOps\, 
 but to enhance it.\n\nBecause a fast pipeline only delivers value when it 
 delivers the right system.
