First and foremost, I have to say that while the book seems to paint Goizueta in a positive light, the author is incredibly neutral in their delivery. Many of the major flaws Goizueta made are precisely explained and are never brushed over. I highly recommend a read.
There were two main questions I had while reading this book, and I found answers to both.
**Question 1: Why did Coke buy Columbia Pictures, a business that seemingly has no synergies with Coke?**
The decision was mostly due to the ongoing Pepsi-Coke war. As Goizueta saw Coke's market share decline while Pepsi's increased, the mathematical side of him concluded that drastic action was necessary to prevent Coke from becoming a company of the past. Fearing the company's demise, Goizueta decided to diversify while they could. Columbia Pictures seemed like a viable option at the time. They also considered Disney but decided against it because it was a poorly run company, surviving mostly on its legacy copyrights (a situation Warren Buffett capitalized on, making terrific bets on both Disney and Coke, the latter of which still yields him dividends to this date).
**Question 2: Why did Coke change its formula?**
The author portrays Goizueta as an engineer countless times throughout the book, and this episode truly showed it. Here's my understanding of how engineers often think: they approach problems in a highly theoretical, number-driven way.
During Pepsi's blind taste test marketing campaign, people overwhelmingly chose Pepsi over Coke because Pepsi is sweeter. However, the campaign shouldn't be interpreted simply as "people pick Pepsi because it's better." As a former Pepsi CEO explained, it was all about fun. Pepsi's blind tests branded it as a more fun, lighthearted alternative to Coke, which was more established and widely seen as "the taste of America." Extrapolating the results as a purely scientific preference for one product over another is a very engineering-centric way to understand human choice.
New Coke was launched, as the author noted, after rigorous blind tests of various alternative formulas. The goal was to find a new drink that would consistently outperform Pepsi in these tests, and in that, they succeeded. The New Coke did perform better than Pepsi in a statistically significant way; Coke's own internal studies showed that 53% of people preferred New Coke over Pepsi, which stood at 47%. It was a small difference, but it was big enough to convince Goizueta.
But the real question is, how do you truly quantify preference scientifically? People preferred Coke not because it was unabashedly and categorically better than any alternative, but rather out of the comfort of yesterday. On the other hand, Pepsi was succeeding because it branded itself as something new, innovative, and the underdog. The entire product proposition was more symbolic than actual, and people often operate based on symbols, especially when it comes to preferences.
Why do some girls prefer pink? Why do many Asians prefer rice? Why do Americans watch American football while Europeans go nuts over soccer? It would be pointless to use a scientific study to quantify the health benefits of rice or the "watch-ability" of American football versus European soccer in America because, fundamentally, people make these choices out of inertia, norms, and comfort.
New Coke—as we now know—failed spectacularly, not because it tasted bad, but because it wasn't the product Coke buyers wanted. As I am typing this today, with Coke having long reverted to its original formula, Pepsi has seen a steady decline in its market share. (I should add, however, that PepsiCo is vastly more diversified today, so they aren't as worried as one might think.) Meanwhile, Coke has mostly retained its prior lead and continues to be the de facto soft drink choice for most people around the world.
(Overall, this was a very enjoyable read. I also learned more than I expected about Coke's struggles with its bottlers during Goizueta's reign and its many failed adventures outside of the soft drink world that I didn't even know about before.)
