“I Thought You Meant…”: The Hidden Assumptions Breaking Your Business

The most expensive failures in business rarely come from bad strategy and instead come from assumptions no one ever said out loud.

Maartje van Krieken looks at how unspoken assumptions quietly undermine decision making, weaken business alignment, and slow execution long before problems show up on a dashboard. She reframes assumptions as hidden requirements for success and explains why shared language often masks very different realities. Teams leave meetings believing they agree, yet they move forward with conflicting interpretations that later surface as friction, stalled progress, or blame. How often does alignment exist in theory but not in practice?

Drawing on disaster management, Maartje offers a more resilient approach to leadership under pressure. Operational resilience depends on naming what is believed to be true, revisiting assumptions on purpose, and treating course correction as competence rather than failure. AI, she cautions, does not remove assumption risk and can deepen it when clarity is missing. The real work lies in making assumptions visible, defining tripwires, and updating decisions as reality shifts. The question for leaders is simple: are you managing the plan, or managing the assumptions holding it together?
