Key takeaways

  • An industry's value chain lists every step from raw material to the final customer.
  • Unit economics asks one question: does one unit (one order, one customer, one store, one seat, one flight) make money after its own costs, and how many units are needed to cover everything else?
  • A supply chain moves materials from suppliers to customers. Its job is to meet demand on time at the lowest total cost, which includes transport, inventory and the cost of running out.
  • Industries differ in where each dollar of sales goes (materials, people, research or machines), so a margin that is healthy in one industry can be a warning sign in another.
  • A business model answers two questions: who pays, and for what. The same product can be sold in very different ways, and each way has its own numbers to watch.
By the end you will be able to
  • Draw the value chain of any industry and find where the profit concentrates
  • Choose the natural unit of a business and calculate contribution, breakeven, CAC, LTV and payback
  • Explain lead times, inventory, working capital, the bullwhip effect and total landed cost
  • Judge whether a margin is good by comparing it with the right industry benchmark
  • Name the main business models and the metric that matters most in each
  • Run a 10-minute industry scan using free annual reports and earnings calls
