Business strategy

Grove, who ran Intel, defines it as the moment when a business's fundamentals shift so that the previous strategy stops working: a technology, a regulation or a competitor changes the rules. His thesis is that these points are recognised late, and that surviving them demands deliberate paranoia — questioning the business's assumptions before the market does.

Because it separates two things that are often conflated: the tools (kanban, jidoka, continuous improvement) and the culture that sustains them. Liker documents that companies which copied the tools without the underlying philosophy achieved temporary gains that later reversed. It is a case study in why management practices do not transplant cleanly.

Theranos illustrates how a convincing narrative, a prestigious board and a funding round can substitute for technical evidence for years. For anyone analysing companies, the value lies in identifying the signals the environment ignored: internal opacity, executive churn, and the absence of independent product validation.

The cases involve large companies, but the mechanisms — focusing resources, measuring what matters, deciding what not to do — scale down better than they scale up. What rarely transfers are the organisational structures and budgets, which presuppose a size most companies never reach.
