The Longitude Board denied John Harrison his prize not because his clock failed, but because they feared his masterpiece was an unreplicable "one-off." They needed a solution that could be mass-produced for the entire fleet. This shows how large organizations prioritize scalable systems over individual, bespoke brilliance, even if the latter is technically superior.

In early WWII, different US Army battalions created their own custom jackets, leading to a logistical nightmare of incompatible, limited-edition gear. This illustrates how decentralized innovation without a unifying strategy results in inefficiency and chaos.

Frank Kendall was shocked to find that major decisions on new military programs were often made "by the seat of our pants" based on a four-star general's preference. This lack of rigorous, data-driven operational analysis leads to suboptimal investments and wasted billions, a problem he tried to fix by elevating the analysis organization.

Leaders invest heavily in flawed products because their personal effort creates an emotional attachment, a cognitive bias known as the IKEA effect. They rationalize this by citing outliers like Steve Jobs, ignoring the vast majority who fail with this "strategy."

The need to liquidate millions of overproduced M43 jackets after WWII created the modern surplus industry. These stores made scientifically tested, high-performance clothing available to everyone, effectively becoming the "Walmart before Walmart" for functional apparel.

At NeXT, Steve Jobs' perfectionism became a trap. His constant tinkering with product design caused massive delays, increased costs, and made technology less novel by the time it was ready. This highlights the danger of pursuing a perfect vision at the expense of execution.

Named after a doctor whose life-saving hand-washing theories were rejected, the Semmelweis reflex describes the tendency to ignore new evidence that conflicts with existing paradigms. Accepting the new idea would force an admission of past error, which is psychologically difficult. This is a crucial barrier to overcome when selling new ideas internally.

The US simply imitated the wool overcoats of dominant European armies. This resulted in uniforms ill-suited for the wet, muddy conditions of trench warfare, demonstrating the danger of blind imitation without considering the specific use case.

The US military's intensive research for a single "perfect jacket" concluded that no such thing exists. The real breakthrough was a modular system of layers—a liner, a shell, and a parka—that could be adapted to any environment, revolutionizing apparel design.
