How Big Things Get Done

Introduction: Why Large Projects Fail and How to Succeed

California voters approved a high-speed rail to connect Los Angeles and San Francisco for $33 billion in 2008. Fourteen years later, the project serves as a cautionary tale of poor planning and premature execution. Costs have ballooned toward $100 billion, and the current plan only covers a short inland segment. This failure illustrates a common pattern where big dreams are launched in a rush of excitement but eventually stall under the weight of delays and rising expenses.

The world of large-scale projects is governed by a disheartening reality known as the Iron Law of projects. Data from over 16,000 projects across 136 countries reveals that only 8.5 percent of projects meet their original goals for both cost and schedule. Even more shocking, a mere 0.5 percent actually achieve what they set out to do on time and within the intended budget. A primary reason for these failures is that project risks are fat-tailed, meaning there is a much higher probability of extreme, disastrous outcomes than most planners realize.

A completely different approach was taken during a massive school-building project in Nepal. Bent Flyvbjerg, who served as the planner, helped oversee the construction of twenty thousand schools in remote areas. While such international aid projects often fail, this one finished eight years ahead of schedule and on budget. The buildings were so well-designed that they survived a major earthquake years later, proving that careful preparation yields better results than a rushed start.

Two universal forces drive the outcome of any project: human psychology and political power. Psychology refers to the human tendency toward over-optimism and poor judgment, while power involves the political maneuvering and personal interests that can derail a plan. These forces often lead people to think fast and act slow, resulting in projects that drag on for years. The longer a project takes to complete, the longer its window of vulnerability remains open to unexpected events like economic shifts or pandemics.

To succeed, leaders must do the exact opposite: think slow and act fast. The Empire State Building is a perfect example of this disciplined approach. Before construction began, the architects meticulously planned every detail, essentially finishing the building on paper down to the exact number of rivets. This preparation allowed the actual building process to move like a high-speed assembly line, finishing under budget and ahead of schedule.
