Key ideas in Business Logic: Clear Thinking About Money

  • A spike in sales occurring alongside an ad campaign does not prove the campaign caused the surge
  • External events, such as competitor outages or seasonal demand, often explain sudden revenue changes
  • Attributing revenue to your own actions without checking for alternative explanations leads to wasted budget
  • Studying only successful companies creates a skewed picture because failed attempts with identical traits are excluded from view
  • A trait shared by winners cannot be credited with their success if many losers shared the exact same trait
  • Sound business logic requires looking at both successes and failures within a cohort
  • Financial projections that show explosive revenue without rising costs depend on hidden operational assumptions
  • Growing without marketing spend assumes unpaid organic growth or referrals will do the heavy lifting
  • Uncovering unstated premises reveals the true operational risks hidden behind attractive charts
  • A real business strategy defines clear, observable conditions that would prove its core hypothesis wrong
  • A claim that reinterprets every failure as proof that 'the market isn't ready' cannot be tested or improved
  • Persuasive delivery, charm, and storytelling ability have no impact on the underlying unit economics of a product
  • A business that loses money on every customer sale cannot survive on executive enthusiasm alone
  • Evaluating a proposal requires stripping away presentation style to analyze the basic math of costs and pricing
  • Money already spent cannot be recovered regardless of what you do next
  • A venture is only worth continuing if future returns exceed future costs
