The persistent belief that "this time will be different" is often the single greatest threat to any project's success,

and Part of The Bias Files, Adele Ashcombe's insightful book explores why every plan inevitably runs late and

over budget.

Optimism shifts from a motivating force into a blind spot when initial projections fail to account for inherent

uncertainties, turning hopeful estimates into unrealistic expectations. *Behind Schedule, Over Budget* is not a

project management manual, a cost-cutting guide, or a time-saving hack. Instead, it unpacks the psychological

roots of optimism bias and reveals how unchecked hope systematically sabotages even the most

well-intentioned endeavors.

Through illuminating real-world examples - from architectural marvels to literary ambitions and startup

ventures - you will explore:

- The Illusion of Certainty: Why confidently stated timelines, like those surrounding the Sydney Opera

House's completion date, rarely survive first contact with reality.

- Hidden Renovation Costs: How seemingly minor project adjustments, such as a kitchen remodel, quickly

snowball into significant budget increases due to unforeseen complications.

By understanding these predictable patterns of thought, *Behind Schedule, Over Budget* equips you with the

awareness to challenge unrealistic projections, build in necessary buffers, and foster more honest conversations

about risk-ultimately leading to projects grounded in practicality rather than wishful thinking. Learn to

recognize optimism bias in yourself and others, mitigating its damaging effects before they derail your next

undertaking. Pick up *Behind Schedule, Over Budget* now and start building a future where projects finish

closer to reality, not further from it.
