After Wirecard AG (Wirecard) collapsed in 2020, the financial technology (fintech) company, revealed as an elaborate fraud, came to be known as Germany’s Enron as investigators confirmed many of the concerns that had been raised by whistle-blowers and journalists. For instance, they confirmed that the company was using round-tripping to inflate revenues and that escrow accounts in Southeast Asia did not exist. Auditors had raised concerns for years, but then signed off on the company’s financial statements. What were the responsibilities of regulators and auditors with regard to the company, and what red flags should they have paid attention to?

The case describes the challenges faced by Ford and other automobile manufacturers in an era of declining oil reserves and volatile fuel prices. The Ford diesel decision seems to reflect classic thinking constrained by mental models that were developed in a different world. Diesels constitute over 50 per cent of automobile sales in Europe, because fuel is extremely expensive there. If fuel gets extremely expensive in the United States, one would expect diesels to become more attractive. Yet Ford seems to be stuck in the old mental model that says Americans don't like diesels. Ford can't prove in a PowerPoint presentation that there is a big market for small diesels - mostly because there are few small diesels available to U.S. consumers. But that traps them into a position where they will never lead the industry or innovate outside of current market and technology conditions.

Discusses the introduction of a completely new beverage to the U.S. market. New Century Brewing, which is owned by one of the founders of Boston Beer Co., is a small brewer that outsources production to third-party brewers. It has two products, a light craft beer sold in upscale shops and restaurants, and a caffeinated beer, which is oriented toward younger drinkers mainly between 21 and 25 years of age. Moonshot, created by the legendary masterbrewer, known as the "father of light beer," became the first caffeinated beer in the world. The company follows a differentiation strategy that attempts to appeal to a small niche of customers traditionally ignored by large brewers. Shortly after the introduction of each of its products, large competitors introduced similar products. Nevertheless, Moonshot has a first-to-market advantage that could potentially be leveraged.
